Track Rod End replacement & repair made easy

What is a track rod end replacement?

The track rod end is a crucial part of your vehicle’s steering system. It connects the steering rack to the steering knuckle on each front wheel, helping translate your steering wheel input into movement of the wheels. The track rod end contains a ball joint that allows for smooth pivoting as the suspension moves, ensuring the wheels can steer and absorb road movement at the same time.

If a track rod end fails, your vehicle’s steering may become loose, less responsive, or even dangerous to control, particularly when cornering or driving at speed.

During a track rod end replacement, a mechanic will first lift the vehicle and remove the front wheels to access the steering components. The faulty track rod end is then disconnected from the steering knuckle and unthreaded from the track rod. A new track rod end is fitted in its place and securely tightened to the correct torque.

Are the track rod end and ball joint the same?

While the track rod end and the ball joint are similar in design and both use a ball-and-socket mechanism, they serve different purposes and are located in different parts of the vehicle. The track rod end is a component of the steering system, connecting the steering rack to the steering knuckle to allow the wheels to turn. The ball joint, on the other hand, is typically part of the suspension system, connecting the control arms to the steering knuckle. It allows the suspension to move up and down while maintaining steering control. So while they function in similar ways, they are not the same part and serve different roles in how your vehicle handles and rides.

How do I know my track rod ends need replacing?

One of the primary reasons for needing a track rod end replacement is an MOT failure or advisory, often linked to the rubber boot becoming damaged or worn. This boot is designed to protect the internal components from water and road debris, and when it fails, the part is more susceptible to damage.
However, other signs could indicate wear in the track rod end, including:

• Steering wheel vibrations
• Clunking noises when driving over bumps or turning
• Uneven tyre wear or tyres wearing out faster than usual
• Steering that feels loose or unresponsive

If you're experiencing any of these issues, it may be time to have your track rod end inspected or replaced.

What happens during a track rod end replacement?

The track rod end replacement is a common repair for maintaining your vehicle's steering system:
First, the mechanic ensures that the car is safely parked on a level surface, with the parking brake engaged and the engine turned off. This step ensures safety while the vehicle is worked on. The mechanic will then:

• Lift the Vehicle: The mechanic raises the front of the vehicle and removes the road wheel to access the track rod ends and other steering components.

• Inspect the Track Rod End: The mechanic inspects the track rod end and tie rod for any signs of wear, movement, or damage. This is done to confirm that the track rod end is the source of the issue.

• Remove the Faulty Track Rod End*: The mechanic carefully removes the old, worn-out track rod end from its position on the steering assembly, ensuring no damage is done to other parts. As this is a component that is open to the elements and frequently covered in road debris and water, it is not uncommon for the track rod end to be seized in position. There are cases where some heat is required in order to undo the retaining nuts and also for a ball joint splitter to be used to prise the part out of the steering knuckle.

• Install the New Track Rod End: A new track rod end is installed, making sure it is properly aligned and securely fastened.

• Tighten Components: The mechanic ensures all components are tightened to the manufacturer’s specifications to guarantee everything is properly secured.

• Reassemble the Vehicle: The road wheel is reattached, and the vehicle is carefully lowered back to the ground.

Once the replacement is complete, the mechanic may test the steering to ensure the new track rod end is functioning as it should. Replacing the track rod end helps keep your steering system in top condition, ensuring your vehicle remains safe to drive.

What causes track rod end wear?

Track rod ends wear out over time due to a combination of regular use, road conditions, and exposure to the elements. They contain ball joints that move constantly as you steer and as the suspension moves, which naturally leads to wear. Common causes include:

• Potholes and rough roads: Repeated impacts can strain or damage the joints.
• Water, dirt, and road salt: These can enter the joint if the protective rubber boot is damaged, leading to corrosion and accelerated wear.
• Age and mileage: Like many moving parts, track rod ends simply wear down over time, especially on high-mileage vehicles.
• Lack of lubrication (in some types): Some track rod ends are sealed units, but if the seal breaks or they’re not properly lubricated, the joint can deteriorate faster.

Should track rod ends be replaced in pairs?

Generally, yes. If one has worn out, the other may not be far behind, especially if both have been exposed to the same driving conditions. Replacing them in pairs can help ensure balanced steering performance and even tyre wear.

Can you drive on damaged track rods?

We would strongly advised not to drive with damaged or worn tie rods (which include the track rod ends). Damaged tie rods can cause loose, unpredictable steering and significantly affect your ability to control the vehicle! In severe cases, a completely failed tie rod can cause a total loss of steering, which is extremely dangerous. If you suspect a problem, it’s best to have your vehicle inspected and repaired as soon as possible.

What does this repair cover?

Unless otherwise stated, the quote for your track rod end(s) to be replaced will cover:

• The cost of the track rod end(s)
• Coming to you
• Fitting of the parts
• Disposal of the old parts (unless you request to keep them)
• VAT (if applicable)
• 12 months parts and labour warranty

What the quote will not cover: After any repair work on suspension and steering, the wheel alignment should be checked and adjusted accordingly. This is most important after a track rod end replacement as it is the main component used to adjust the tracking. Therefore, whilst a track rod end can be changed by a mobile technician, you will then need to take the vehicle as soon as possible to a tyre centre to have the wheels aligned.

How much does it cost to replace a track rod end ball joint in the UK?

The cost to replace a track rod end (which includes the ball joint) typically ranges from £90 to £150 in the UK, depending on your vehicle’s make and model. This price usually covers both parts and labour.
If a wheel alignment is required after the repair (which is often recommended), that could add an extra £30–£50 to the total cost.

Can a mobile mechanic perform a track rod end replacement?

Due to the complicated nature of this job, a mechanic would likely rather perform the track rod end replacement in a garage. With ClickMechanic, you can take advantage of free collection and delivery services to a nearby garage, as long as the car is drivable. It is also possible for a mobile mechanic to complete the job; however, it depends on the mechanic and you will then need to take the vehicle as soon as possible to a tyre centre to have the wheels aligned.
