The Ultimate Car Suspension Tools Guide For Beginners

Car Suspension Tools Guide main 1

Ever hit a pothole and heard an unpleasant clunk from somewhere beneath your car? Perhaps your steering feels slightly loose, there’s a knocking noise when driving over speed bumps, or your mechanic has mentioned worn suspension bushes on your latest MOT.

Problems like these can be frustrating, particularly when you’re unsure what’s causing them or how complicated the repairs might be.

Your car’s steering and suspension systems work together to keep the vehicle stable, absorb bumps and maintain tyre contact with the road. Unfortunately, many of the components involved are tightly fitted, difficult to access or subjected to considerable mechanical forces. Even a relatively straightforward repair can become challenging without the appropriate equipment.

That’s where specialist tools make a difference.

This beginner-friendly car steering and suspension tools guide explains the equipment used for common repairs, including ball joint removal tools, split hub spreaders, strut wrenches, coil spring compressors and suspension arm levers.

You’ll learn what each tool does, when you might need it and how to choose suitable equipment for the job. We’ll also cover important safety considerations, common suspension problems and practical advice for anyone building a home garage toolkit.

Whether you’re learning to maintain your own vehicle or starting out as an apprentice mechanic, understanding these tools is a useful first step towards tackling suspension repairs with greater confidence.

Quick Answer: What Tools Do You Need for Car Suspension Repairs?

The specialist tools required for car suspension repairs depend on the vehicle and the components being replaced. Common examples include:

  • Split hub spreaders: Release struts and certain ball joints from split-clamp mountings.
  • Ball joint separators and presses: Separate or remove tightly fitted suspension joints.
  • Coil spring compressors: Control spring compression during applicable suspension repairs.
  • Strut nut sockets and wrenches: Help remove specialist strut fasteners while holding the damper shaft.
  • Suspension arm levers: Provide controlled leverage when positioning suspension arms.
  • Specialised hub nut sockets: Fit high-torque hub and driveshaft fasteners.
  • Bush and bearing removal kits: Press fitted bushes and bearings in or out of their housings.

You’ll also need suitable vehicle lifting equipment, correctly rated axle stands, appropriate hand tools and a torque wrench.

Understanding Car Steering and Suspension Systems

Before choosing your tools, it helps to understand the components you’re working with.

A car’s steering system controls the direction of the wheels, while its suspension manages movement between the wheels and the vehicle body. They perform different jobs, but the two systems are closely connected.

When you turn the steering wheel, accelerate, brake or drive over uneven ground, numerous components work together to keep the tyres in contact with the road.

Problems with any of these components can affect handling, stability and tyre wear.

How Does a Car’s Suspension Work?

Most modern passenger cars use independent suspension, allowing the wheels on the same axle to move with a degree of independence.

Although designs vary, you’ll regularly encounter two common arrangements.

car supsension tools guide 2

MacPherson Strut Suspension

MacPherson strut suspension is widely used on modern cars, particularly at the front.

The arrangement combines a telescopic shock absorber with a structural strut assembly, commonly surrounded by a coil spring. A lower control arm helps locate the wheel, while the steering knuckle connects the suspension to the hub and steering components.

Its compact design makes efficient use of space, which is particularly useful in front-wheel-drive vehicles.

However, replacing components can involve separating tightly clamped struts, controlling spring tension and removing fasteners that are difficult to access.

Typical tools used on MacPherson strut suspension include:

  • Split hub spreaders
  • Strut nut sockets and wrenches
  • Coil spring compressors
  • Suspension arm levers
  • Ball joint removal tools

Workshop tip: Before ordering any specialist suspension tool, establish whether your vehicle uses a split-clamp strut mounting or a conventional bolted arrangement. The removal method, and therefore the tools required, can differ considerably.

Double Wishbone Suspension

Double wishbone suspension uses upper and lower control arms to locate the wheel assembly.

The arrangement gives manufacturers considerable control over wheel geometry as the suspension moves. You’ll encounter variations on performance vehicles, larger cars and some SUVs.

Repairs frequently involve working with:

  • Upper and lower ball joints
  • Control arm bushes
  • Suspension arm mountings
  • Coil springs and shock absorbers
  • Specialist fasteners and alignment components

Unlike a typical MacPherson strut arrangement, the spring and damper may be separate components. Their positioning also varies between vehicles.

This is particularly important when dealing with spring-loaded suspension arms, where releasing the wrong mounting can allow stored energy to act on components unexpectedly.

Why Do Suspension Repairs Need Specialist Tools?

You can complete plenty of routine vehicle maintenance with a decent socket set, spanners and screwdrivers.

Suspension work is different.

Components are often pressed, clamped or tapered together to withstand substantial forces during everyday driving. Add years of exposure to rain, road salt and corrosion, and removing them can become surprisingly difficult.

Three problems are particularly common.

1. Tight or seized fittings

Ball joint pins, steering joints and strut mountings can remain firmly seated even after their retaining fasteners have been removed. Applying excessive force with an unsuitable tool risks damaging the components you’re trying to separate.

2. Restricted access

Suspension components sit close together, often surrounded by brake pipes, driveshafts, wiring and other vulnerable parts.

A conventional socket or spanner might not fit, while specialist tools are designed to access the fastener or component without unnecessary dismantling.

3. Stored mechanical energy

Coil springs can store enough energy to cause serious injury if released uncontrollably. Some suspension configurations can also place considerable loads on control arms and other components.

This makes identifying the suspension arrangement and following the manufacturer’s repair procedure essential.

Safety note: Suspension work affects vehicle handling and roadworthiness. This guide explains tool selection and general repair considerations; it is not a substitute for vehicle-specific workshop instructions or training. Spring compression and other safety-critical operations should be carried out by competent people using approved equipment.

7 Essential Car Steering & Suspension Tools Explained

car supsension tools guide 7

Not every repair requires all seven tools covered below.

If you’re replacing a track rod end, for example, you might need a suitable joint separator but have no reason to touch a coil spring compressor. Replacing a complete MacPherson strut assembly could involve an entirely different combination of equipment.

Understanding these differences will help you avoid buying unnecessary tools or attempting to improvise with unsuitable ones.

1. Suspension Split Hub & Ball Joint Spreaders

A split hub spreader is designed to open certain split-clamp mountings in steering knuckles or hub carriers, allowing components such as suspension struts to be removed.

It’s particularly useful on vehicles where the base of the suspension strut fits inside a clamped opening rather than being secured by conventional mounting bolts.

How Does a Split Hub Spreader Work?

Imagine trying to pull a tightly fitted metal tube out of a clamp.

Even after removing the clamp bolt, the two surfaces may continue gripping one another. Trying to force them apart with an oversized screwdriver can damage the clamp or surrounding components.

A split hub spreader works by carefully expanding the slot by the small amount needed to release its grip, provided the mounting is designed for that method.

This allows the component to be separated with less risk of damage than uncontrolled hammering or levering.

When Would You Use One?

Split hub spreaders are commonly used during:

  • MacPherson strut removal and replacement
  • Certain steering knuckle repairs
  • Suspension damper replacement
  • Removal of compatible split-clamp ball joint mountings

Not all steering knuckles use this design, so always check the vehicle’s repair instructions before selecting a spreader.

Recommended Jawel Tools Product

Suspension Split Hub & Ball Joint Spreader

A specialist spreading tool intended for compatible suspension and hub mountings where controlled expansion is required.

Practical tip: Clean the area around the clamp before attempting removal. Built-up rust and dirt can conceal the retaining arrangement or prevent the strut from moving freely. Never force a clamp beyond the vehicle manufacturer’s specified limits.

2. Ball Joint Removal Tools & Presses

Ball joints connect suspension and steering components while allowing movement through different angles.

You’ll commonly find them connecting control arms to steering knuckles and within steering linkages, where joints such as track rod ends allow movement while transmitting steering forces.

Because many of these joints use tapered pins secured inside matching tapered holes, removing them can take considerably more effort than simply undoing a nut.

This is where a ball joint removal tool becomes useful.

Different Types of Ball Joint Removal Tools

car suspension tools guide 3

There are several designs, each intended for a particular task.

Fork-Type Ball Joint Separators

Often called pickle forks, these have a forked wedge that fits between the joint and its mounting.

They’re useful for separating stubborn joints but can damage rubber dust boots, making them less suitable when the joint needs to be reused.

Screw-Type Ball Joint Separators

These tools use a threaded mechanism to apply controlled pressure against the joint pin.

A correctly sized separator can reduce the need for impact, although poor positioning or excessive loading can still damage the joint or its surrounding components.

C-Frame Ball Joint Press Kits

These use a rigid frame and interchangeable adapters to press compatible ball joints into or out of their housings.

They’re particularly useful for certain press-fit ball joints, but they serve a different purpose from separators used to release tapered pins.

Feature Fork Separator Screw-Type Separator C-Frame Press
Main Purpose Separate tapered joints Separate tapered joints Remove/install compatible press-fit joints
Operating Method Wedge and impact Threaded pressure Pressing force
Dust Boot Damage Risk Higher Generally lower with correct use Depends on application
Common Use Joint replacement Controlled joint separation Press-fit ball joint replacement

Which Type Should You Choose?

The correct choice depends on what you’re actually removing.

For separating a tapered track rod end or ball joint pin, a screw-type separator may be appropriate. When replacing a press-fit ball joint within a control arm, you’ll usually need a suitable press and matching adapters.

It’s worth checking whether replacement of the complete control arm is recommended for your vehicle. Some modern suspension components have integrated ball joints that aren’t intended to be replaced individually.

Recommended Jawel Tools Product

Lower Control Arm & Ball Joint Removal Tool — Sealey VS3849

This specialist tool appears in the Jawel Tools product range and is intended for lower control arm and ball joint removal applications.

Before purchasing, check its specific application against your vehicle, as suspension joint designs and tool fitment vary.

Explore the Jawel Tools Ball Joint Removal Tools category for more options.

Workshop tip: If a ball joint dust boot is already split, inspect the condition of the joint itself rather than assuming the problem can be solved by fitting a replacement boot. Water and road grit can enter through damaged rubber and accelerate wear.

3. Coil Spring Compressors

A coil spring compressor is used to control the compression of a suspension spring during certain repair procedures.

On many MacPherson strut assemblies, the spring remains under considerable load even after the assembly has been removed from the vehicle. The spring must therefore be safely restrained before components such as the upper spring seat or retaining hardware can be removed.

This makes spring compressors among the most safety-critical tools used in suspension servicing.

What Types of Coil Spring Compressors Are Available?

Portable threaded spring compressors

These typically use threaded mechanisms and gripping jaws to compress compatible coil springs.

They’re relatively compact and can be useful for occasional workshop applications, provided the design is suitable for the spring and the manufacturer’s instructions are followed.

Professional bench or floor-mounted compressors

Often found in busy automotive workshops, these provide a dedicated setup for spring compression.

Depending on the equipment, they may incorporate adjustable spring supports, guarding and additional restraint systems.

Hydraulic or air-operated compressors

These use powered mechanisms to apply the required force, reducing the amount of manual effort involved.

They still require correct spring positioning, compatibility checks and appropriate safety precautions.

Essential Coil Spring Compressor Safety

A compressed suspension spring can release energy extremely violently if the equipment fails or becomes disengaged.

Before any compression work:

  1. Identify the correct repair procedure. Establish how the spring is retained and whether compression is required for the particular vehicle.
  2. Check tool compatibility. Confirm that the compressor is suitable for the spring’s shape, dimensions and load.
  3. Inspect the equipment. Damaged threads, worn jaws, bent components or missing retaining devices are reasons to stop.
  4. Follow the compressor manufacturer’s instructions. This includes approved lubrication, positioning, restraints and permitted drive tools.
  5. Keep clear of the spring’s potential release path. Never position yourself where an uncontrolled spring or compressor component could strike you.
  6. Do not release spring-retaining fasteners until the spring load has been safely controlled and verified.

Never assume an impact wrench is safe to use on a spring compressor. Some compressors prohibit powered impact tools because they can overload or damage the mechanism.

Likewise, an improvised ratchet strap should not be treated as a substitute for an approved spring restraint system.

For anyone inexperienced with coil spring compression, having the work performed by a trained mechanic with suitable professional equipment is the safer option.

Recommended Jawel Tools Products

Jawel Tools stocks several spring compressor options, including:

  • Coil Spring Compressor 3pc with Safety Hooks — Sealey AK384
  • Coil Spring Compressor 1000kg 2pc — Sealey AK3841

  • Professional Coil Spring Compressor Set 2500kg — Sealey RE229
  • Hydraulic Coil Spring Compressor 1000kg — Sealey VS7011

Different compressors have different spring compatibility requirements and rated capacities. A higher load rating alone does not make a compressor suitable for every type of spring.

Browse the Coil Spring Compressors category to compare the available equipment.

Worth knowing: You won’t always need to compress a spring to replace a worn suspension component. For example, a complete preassembled strut and spring unit may be installed without dismantling its spring assembly, depending on the vehicle and replacement part.

However, a complete strut assembly must still be removed and refitted according to the vehicle manufacturer’s procedure.

4. Strut Nut Sockets & Strut Wrenches

Strut nut sockets and wrenches are designed to help remove or refit fasteners on suspension strut assemblies.

One problem frequently encountered during strut repairs is the shock absorber piston rod rotating when you attempt to turn its retaining nut.

You can sometimes feel the nut becoming loose, only to discover that the entire shaft is rotating with it.

A conventional socket doesn’t necessarily provide a way to hold the piston rod stationary.

How Do Strut Nut Sockets Work?

Specialist strut tools often use a hollow socket or offset wrench arrangement that allows the technician to hold the damper shaft while turning the retaining nut.

Depending on the vehicle, the shaft may require:

  • An Allen or hexagonal key
  • A Torx bit
  • A two-point holding tool
  • A manufacturer-specific strut socket

The tool must fit both the retaining nut and the shaft’s holding feature.

It’s worth noting that some strut designs require dedicated manufacturer’s tools or procedures. A universal strut wrench won’t necessarily fit every vehicle.

Why Not Just Use an Impact Wrench?

An impact wrench might remove certain strut fasteners, but it isn’t automatically the correct tool for every shock absorber.

Some damper manufacturers specifically warn against allowing the piston rod to rotate or using impact tools on their assemblies.

Potential problems include internal damper damage and incorrect tightening.

For final assembly, use the specified tightening method and torque value. Never grip the polished piston rod with pliers or a pipe wrench, as surface damage can compromise the damper seal.

Workshop tip: Before attempting to loosen any strut top fastener, identify whether you’re dealing with a mounting fastener or the central spring-retaining nut. They have different functions, and accidentally releasing a spring-retaining nut under load can cause serious injury.

5. Suspension Arm Levers & Pry Bars

Suspension arms are designed to move as the vehicle travels over uneven surfaces, but that movement can make some repairs awkward.

For example, when separating a strut from its lower mounting or positioning a control arm, the suspension’s bushes and geometry may resist the movement needed to remove or refit a component.

A suspension arm lever provides additional mechanical advantage, helping a mechanic move a compatible suspension arm in a controlled manner.

Why Use a Specialist Suspension Arm Lever?

A conventional pry bar can provide leverage, but maintaining pressure while simultaneously positioning a component can be difficult.

Depending on the vehicle, a second person might otherwise be needed to assist.

Specialist suspension arm levers are designed to help with these situations, allowing more controlled positioning and, in certain designs, hands-free operation.

They can be particularly useful during:

  • MacPherson strut removal
  • Lower control arm replacement
  • Certain ball joint repairs
  • Suspension assembly positioning
  • Reinstallation of compatible components

However, the tool must be positioned according to the manufacturer’s instructions.

Incorrect leverage can damage brake pipes, ABS wiring, driveshaft joints or suspension bushes.

Hands-Free Suspension Arm Levers

Hands-free versions are particularly useful when the technician needs both hands available for another part of the job.

Rather than continuously holding a pry bar, a suitable hands-free lever can maintain the required positioning while components are aligned or handled.

This doesn’t mean the tool makes every suspension repair a one-person operation. Additional support may still be required, especially when dealing with heavy hub assemblies.

Workshop tip: If a suspension arm won’t move as expected, don’t automatically apply more force. Check whether another component is restricting movement, whether the suspension is still loaded and whether the manufacturer’s procedure calls for a different method.

6. Specialised Hub Nut Sockets

Hub nut sockets are designed to fit the large fasteners used on wheel hubs, driveshafts and related assemblies.

These fasteners often require substantial tightening torque and may be secured using a locking or staking arrangement.

As a result, you might find that an ordinary socket set doesn’t include the correct size or design.

What Makes Hub Nut Sockets Different?

Depending on the application, specialist hub nut sockets may feature:

  • Larger socket sizes
  • Deep profiles for protruding shafts
  • Heavy-duty construction
  • Specific internal profiles
  • Vehicle-specific engagement features

Some are manufactured for use with impact equipment, while others are intended for particular hand-tool applications.

Choosing the correct profile is essential. A socket that almost fits can easily round a large fastener, turning a routine repair into a much bigger job.

When Are They Needed?

Hub nut sockets can be required when working on:

  • Driveshaft removal
  • Wheel hub replacement
  • Certain wheel bearing repairs
  • Steering knuckle replacement
  • CV joint servicing

They’re less likely to be needed for a straightforward shock absorber replacement unless the vehicle’s repair procedure also requires driveshaft or hub disassembly.

Browse the Specialised Suspension Sockets category.

Workshop tip: Never assume two vehicles from the same manufacturer use identical hub nut sizes or tightening specifications. Verify the exact model, production year, drivetrain and fastener design before beginning the repair.

Many hub nuts are single-use components. Where specified, fit a new nut and follow the correct torque-and-angle tightening procedure.

7. Suspension Bush & Wheel Bearing Removal Kits

Suspension bushes and wheel bearings are designed to fit securely inside control arms, hub carriers and other suspension components.

Some are pressed into their housings, which makes removal difficult without the right equipment.

A bush or bearing removal kit uses a mechanical or hydraulic pressing arrangement to extract compatible components and install their replacements.

What Does a Suspension Bush Removal Tool Do?

Suspension bushes are commonly made from rubber bonded to metal sleeves or other flexible materials.

They allow controlled movement while helping isolate vibration between suspension components and the vehicle body.

Over time, the material can crack, deteriorate or separate from its mounting.

When replacement is necessary, a suitable bush removal tool applies pressure in a controlled direction to remove the old bush without unnecessarily damaging the surrounding housing.

Some tool kits can also install replacement bushes.

However, not all bushes are designed to be replaced separately. On certain vehicles, the complete suspension arm must be replaced.

How Do Wheel Bearing Puller Kits Work?

Wheel bearing tools perform a related but distinct task.

Depending on the bearing arrangement, they may use threaded rods, receiving cups, sleeves and suitable adapters to push the bearing out of its housing.

A compatible installation tool then applies force to the correct bearing race or mounting surface.

Pressing against the wrong part of a bearing can damage a new component before the vehicle has even left the workshop.

Some modern hub assemblies are supplied as complete bolt-on units and don’t require conventional bearing pressing equipment.

Choosing the Right Kit

Check the following before purchasing:

  • Vehicle make, model and year
  • Bush or bearing dimensions
  • Whether the component is pressed or bolted into place
  • Tool adapter compatibility
  • Required pressing capacity
  • Manufacturer’s removal and installation procedure

For particularly stubborn press-fit components, a workshop hydraulic press may be more appropriate than a portable threaded kit.

Suspension Bush Removal Tools

Wheel Bearing Tools

Workshop tip: Before removing a suspension bush, check its orientation. Some bushes have directional markings, voids or specific installation positions. Fitting one incorrectly can alter suspension behaviour or shorten its service life.

Quick Reference: Suspension Problems & the Tools You Might Need

A knocking noise or unusual steering behaviour can have several possible causes.

The following table provides a starting point for understanding which specialist tools may be involved once the actual fault has been diagnosed.

Symptom or Repair Problem Possible Cause Relevant Tool
Clunking over speed bumps Worn ball joint, bush or anti-roll bar link Ball joint separator or bush removal kit
Strut stuck inside the hub carrier Tight or corroded split-clamp mounting Split hub spreader
Damper shaft rotates when loosening a retaining nut Shaft not being held stationary Strut nut socket or wrench
Suspension arm difficult to position Bush resistance or suspension geometry Suspension arm lever
Worn or damaged coil spring Spring requires replacement Compatible coil spring compressor
Excessive play in a wheel bearing Worn bearing or hub assembly Bearing removal/installation equipment, where applicable
Damaged suspension arm bush Deteriorated bush material Suitable bush removal and installation kit
Driveshaft hub nut difficult to remove High-torque or seized fastener Correctly sized hub nut socket

Important: These are possible explanations, not confirmed diagnoses. A clunking noise, for example, could originate from several different suspension or steering components. The fault should be accurately identified before any parts are removed or tools purchased.

Essential Supporting Tools for Suspension Repairs

The seven specialist tools we’ve covered can make specific jobs easier, but they don’t replace a properly equipped basic toolkit.

Before working on a vehicle’s suspension, you’ll need equipment for safe lifting, correct fastening and inspection.

Trolley Jacks & Axle Stands

A trolley jack is used to raise a vehicle at an approved lifting point, while correctly rated axle stands provide support at the appropriate manufacturer-specified locations.

A hydraulic trolley jack must never be treated as the sole support for a vehicle when anyone is working underneath it.

Choose equipment suitable for the vehicle’s weight, lifting points, ground clearance and required working height.

Browse the Jawel Tools ranges:

If you’re working on a low-slung car, a low-entry trolley jack may be necessary to reach its designated lifting point.

car supsension tools guide 5

Socket Sets, Spanners & Torque Wrenches

Many suspension repairs involve high-load fasteners that must be tightened accurately.

A good selection of metric sockets, spanners, extension bars and appropriate specialist bits will cover many common fastening tasks.

However, final tightening is just as important as removal.

Suspension mounting bolts, wheel bolts, hub nuts and ball joint fasteners may all have specific torque requirements. Some additionally require angle tightening or must be replaced after removal.

A calibrated torque wrench with the correct operating range is essential for these applications.

A common mistake: Tightening a suspension bush pivot bolt while the suspension hangs at full extension can preload certain bonded rubber bushes. Where required, these fasteners must be finally tightened at the manufacturer’s specified suspension position or ride height.

Always follow the vehicle-specific procedure.

Penetrating Oil, Cleaning Tools & Suitable Lighting

Not every useful workshop tool is expensive or complicated.

A wire brush can help remove loose corrosion around accessible fasteners, while a suitable penetrating lubricant may assist with seized fittings where its use is permitted.

Good lighting is equally valuable, especially when identifying hidden mounting bolts, damaged dust boots or retaining clips.

Keep lubricants away from braking surfaces and other components where contamination could cause problems.

Replacing a MacPherson Strut: Understanding the Repair Process

Replacing a MacPherson strut is a useful example of how several specialist suspension tools can be involved in one job.

Although the general principle is similar across many cars, the exact procedure varies considerably between manufacturers and suspension designs.

Some vehicles use split-clamp mountings, while others use bolted connections. Brake hoses, ABS wiring, steering linkages and driveshaft arrangements also affect how the assembly can be removed.

For that reason, the following is an overview of the repair stages and associated tools, rather than a universal dismantling procedure.

Step 1: Identify the Suspension Layout and Required Parts

Before removing anything, establish which strut assembly is fitted and whether you’re replacing the complete assembly or an individual component.

Check the manufacturer’s workshop documentation for:

  • Required replacement parts and fasteners
  • Special tools
  • Suspension support requirements
  • Tightening specifications
  • Wheel alignment considerations

At this stage, you can identify whether a split hub spreader, suspension arm lever or specialist strut wrench will be needed.

Step 2: Prepare and Support the Vehicle

The vehicle must be positioned on suitable firm, level ground and raised using the correct lifting equipment.

Manufacturer-approved lifting and support points should be used, with appropriately rated axle stands or a suitable workshop lift.

The suspension and hub assembly may also require independent support to prevent excessive movement or strain on associated components.

Step 3: Identify and Release the Lower Strut Mounting

On vehicles with a split-clamp mounting, a compatible hub spreader may be used as part of the manufacturer’s strut release procedure.

Other vehicles may use a conventional bolted arrangement.

The surrounding brake hoses, wiring and driveshaft must be protected from excessive movement or loading.

Step 4: Position the Suspension Components

A compatible suspension arm lever may help position the control arm or hub assembly during the work.

However, the correct approach depends on the vehicle’s suspension geometry, spring loading and support requirements.

Using a lever incorrectly can damage suspension components or allow unexpected movement.

Step 5: Remove and Refit the Strut Assembly

The strut must be supported and handled according to the manufacturer’s instructions.

If the complete replacement assembly is supplied with its spring and mounting components already installed, dismantling the spring assembly may not be necessary.

If individual strut components require replacement, additional specialist procedures may be involved.

Step 6: Spring Compression and Component Replacement

Where a spring must be removed from a strut assembly, the work involves potentially dangerous stored energy.

Only competent personnel using a suitable, correctly rated compressor and the prescribed restraint method should perform this operation.

The precise compression, disassembly and reassembly sequence must come from the spring compressor and vehicle manufacturers’ instructions.

A generic online guide cannot safely establish the correct process for every spring, strut and top mounting design.

Step 7: Reassembly, Torque Checks and Alignment

Once the assembly is refitted, all disturbed fasteners and associated components must be checked in accordance with the vehicle’s repair instructions.

This may include:

  • Replacing specified single-use bolts or nuts
  • Tightening fasteners to their required torque or torque-and-angle specification
  • Checking the position of brake hoses and electrical wiring
  • Confirming correct spring and suspension component seating
  • Carrying out required wheel alignment checks

Suspension repairs aren’t finished simply because all the bolts have been refitted.

The vehicle must be inspected for correct operation and roadworthiness before being returned to service.

Steering & Suspension Problems: What Can Fail an MOT?

Suspension wear isn’t only a matter of comfort.

A defective spring, worn joint or insecure mounting can affect how safely a vehicle steers, brakes and handles.

In the UK, the MOT inspection includes checks on suspension components such as springs, shock absorbers, arms, joints and bushes.

According to the Driver and Vehicle Standards Agency’s MOT Inspection Manual, Section 5.3, suspension defects can be classified as Minor, Major or Dangerous, depending on the type and severity of the fault.

Examples of Suspension Defects

Suspension Problem Possible MOT Classification
Fractured or seriously weakened suspension spring Major
Insecure spring with visibly loose fixings Dangerous
Shock absorber with severe leakage affecting function Major
Shock absorber with negligible damping effect Major
Excessively worn suspension joint or bush Major
Suspension joint or bearing likely to become detached Dangerous
Suspension component excessively corroded Major
Suspension component fractured or likely to fail Dangerous

The precise classification depends on the condition found and the applicable MOT inspection criteria.

Not every visible sign of deterioration automatically results in a failed MOT.

For example, the DVSA explains that slight fluid seepage leaving a film on a shock absorber isn’t itself grounds for rejection. Similarly, some suspension bushes are designed to allow noticeable movement.

This is why identifying actual wear or defects matters more than simply replacing anything that looks old.

Can You Drive with a Damaged Suspension Component?

It depends on the fault, but any noticeable deterioration in steering control, unusual wheel movement or suspected structural suspension damage should be treated seriously.

A worn anti-roll bar bush and a ball joint at risk of separation present very different levels of danger.

If you’re unsure whether the vehicle is roadworthy, have it assessed by a qualified mechanic rather than continuing to drive it.

How to Choose the Right Suspension Tools for Your Car

A common beginner’s mistake is choosing tools based entirely on appearance.

A product might look identical to the one used in a YouTube repair video, but a small difference in the mounting arrangement or component dimensions can make it unsuitable.

Before purchasing suspension tools, consider these four factors.

1. Vehicle Compatibility

Check the exact make, model, year and applicable vehicle variant.

Engine size, drivetrain and suspension configuration can all influence which components and tools are fitted.

For vehicle-specific equipment, check the manufacturer’s application list wherever available.

2. The Job You’re Undertaking

Replacing a track rod end requires different tools from changing a MacPherson strut spring or pressing a wheel bearing out of its housing.

Start with the repair procedure, then establish which tools it actually requires.

This avoids buying an expensive kit that doesn’t solve the problem.

3. Tool Quality and Durability

Professional mechanics often choose equipment capable of regular use, but occasional DIY users should still prioritise correct fit, appropriate ratings and reliable construction.

A poorly manufactured puller or press can damage the component being repaired or fail under load.

With safety-critical tools such as spring compressors, compatibility, certification where applicable, inspection and proper operating instructions matter considerably more than the purchase price alone.

4. Buy Individual Tools or a Complete Kit?

An individual specialist tool may be the most cost-effective choice for a single known repair.

A more comprehensive kit could make sense when:

  • You maintain several different vehicles
  • You regularly undertake suspension work
  • You’re equipping a professional workshop
  • You need multiple interchangeable adapters

Whichever option you choose, consider whether replacement parts and suitable adapters are available.

Frequently Asked Questions

Can I Repair Car Suspension with Ordinary Sockets and Spanners?

Some suspension repairs can be completed using conventional hand tools, but others require specialist equipment. Jobs involving compressed coil springs, tightly fitted ball joints, split-clamp strut mountings or press-fit bearings may need purpose-designed tools. Always check the vehicle manufacturer’s instructions before beginning.

What’s the Difference Between a Ball Joint Separator and a Ball Joint Press?

A ball joint separator is generally used to release a tapered joint pin from its mounting. A ball joint press is designed to remove or install compatible press-fit joints within a suspension component. Although the terms are sometimes used interchangeably, the tools perform different tasks.

Do You Need a Coil Spring Compressor to Replace a Shock Absorber?

Not always. The answer depends on the suspension design and whether you’re replacing a complete assembly or individual components. Some shock absorbers are separate from their springs, while certain replacement struts are supplied as complete assembled units. Spring compression may be required when dismantling a loaded strut assembly.

Why Is My Suspension Knocking Over Bumps?

Knocking noises can come from worn ball joints, control arm bushes, anti-roll bar links, strut mounts or other loose suspension components. Several faults can produce similar sounds, so a proper inspection is needed before identifying the cause and choosing the correct repair tools.

Do I Need Wheel Alignment After Replacing Suspension Parts?

Wheel alignment is often recommended or required after replacing components that affect wheel geometry, including certain control arms, steering joints and strut assemblies. The precise requirement depends on the vehicle and the work performed. Incorrect alignment can cause uneven tyre wear, pulling to one side and poor handling.

Can a Beginner Replace a MacPherson Strut?

Some experienced DIY mechanics can replace a complete MacPherson strut assembly with suitable equipment and manufacturer-specific instructions. However, dismantling a spring-loaded strut assembly introduces significant risks. Beginners without the necessary training should leave spring compression and other unfamiliar safety-critical procedures to qualified professionals.

What Suspension Tools Should a Beginner Buy First?

Start with the equipment required for the job you intend to carry out, rather than buying every specialist tool available. Suitable lifting equipment, axle stands, a comprehensive socket set and a torque wrench are common foundations. Add vehicle-compatible suspension tools only when the repair procedure calls for them.

Get the Right Steering & Suspension Tools at Jawel Tools

Steering and suspension repairs become considerably more manageable when you understand the components involved and choose the correct tools for each task.

A split hub spreader can help release a tightly clamped strut, while a suitable ball joint separator makes removing tapered joints more controlled. Specialist wrenches, suspension arm levers and bearing removal kits all have their place, depending on the repair.

However, using the right tools is only part of the job. Safe working practices, accurate diagnosis, vehicle compatibility and correct reassembly are just as important.
