28 November 2025 (updated) Track Rod End: Function, Symptoms & MOT Failures
Track rod ends may seem insignificant, but if they go bad, the outcomes range from minor steering difficulties to serious safety risks. If the steering seems inaccurate or there is uneven tyre wear or knocking noises when turning, this humble part could be to blame. Let’s explore what a track rod end does, how to spot symptoms of wear, and how it could affect your MOT test result.
What is a track rod end?
A track rod end is a pivoting joint that connects the steering rack to the front wheels. It plays a crucial role in translating steering input into directional movement while compensating for suspension travel.
Each front wheel typically has one track rod end, attached to the outer end of a tie rod. The ball joint design allows for vertical and horizontal movement without disconnecting the wheel from the steering mechanism.
There are two types of systems where track rod ends operate:
- Rack-and-pinion steering – most common in modern cars.
- Recirculating ball systems – used in some older or heavy-duty vehicles.
What does it do?
The main function of a track rod end is to:
- Maintain alignment between the wheels and the steering rack
- Allow wheels to pivot smoothly when the steering wheel turns
- Absorb small suspension changes while retaining control
Without properly functioning track rod ends, your vehicle’s steering accuracy, tyre life, and overall safety are compromised.

Signs of a worn or loose track rod end
Worn or damaged track rod ends often show the following symptoms:
- Steering play or looseness: the steering may feel vague or delayed.
- Knocking or clunking noises: especially when turning or going over bumps.
- Uneven tyre wear: misalignment caused by a loose joint will wear tyres quickly in certain spots.
- Vibration in the steering wheel: usually felt at higher speeds.
- Car pulling to one side: a sign of poor wheel alignment.
It’s important to inspect both the ball joint and the protective rubber boot. If the boot is torn, dirt and moisture can enter and cause premature wear, even if the joint is still working normally.
Things to know about wear on the track rod end
All parts of the steering system transmit large mechanical forces. The wheel makes contact with the ground; it also transmits shocks and vibrations to the track rod end. The part does not wear out directly, but it will eventually with long-term and frequent overloading. It then no longer has a firm connection to the wheel and will begin to rattle.
A quick replacement with a new part eventually becomes necessary. You can prevent early wear and tear by avoiding driving too fast on damaged roads and paying attention to kerbs and other obstacles. Check out this visual guide to help you spot the signs:
4 SIGNS OF A WORN TIE-ROD END
Can a faulty track rod end fail an MOT?
Yes, and quite easily.
According to current UK MOT testing standards, a worn, loose, or excessively corroded track rod end will result in a major defect, leading to a test failure. Common MOT failure reasons related to track rod ends include:
- Excessive play in the ball joint
- Torn or missing dust boots, which allow contaminants to enter
- Visible corrosion compromising structural integrity
Even if the joint itself is tight, a damaged boot alone may be grounds for a failure, as it can lead to immediate deterioration.
Can you drive with a bad track rod end?
Driving with a failing track rod end is not recommended. While it may start with subtle steering issues, the problem can rapidly progress to dangerous handling, particularly during emergency manoeuvres or braking.
In severe cases, a track rod end failure could cause you to lose control of the vehicle, especially if the joint separates entirely. This makes a prompt diagnosis and replacement critically important.
How much does it cost to replace a track rod end?
Prices vary depending on vehicle make and model, part quality, and labour charges. Here's a rough breakdown:
- Parts: £10–£40 per track rod end
- Labour: £50–£100 at most UK garages
- Wheel alignment: £30–£60

If you're replacing both sides on an axle, the price doubles, but it’s often recommended to do both at once for balanced handling.

When should you replace it?
Most manufacturers don’t specify a fixed replacement interval. However, track rod ends typically last between 50,000 and 100,000 miles, depending on the following:
- Road conditions
- Driving style
- Part quality
It’s a good idea to inspect them annually, especially if you notice unusual tyre wear or feel changes in the steering system’s response. If you’ve just had suspension work done or hit a severe pothole, check them again.
Preventing premature wear
AUTODOC experts recommend the following to extend the life of your track rod ends:
- Drive on well paved roads and avoid off-road driving where possible
- Keep tyres properly inflated
- Regularly inspect the dust boots for cracks or splits
- Replace worn shock absorbers promptly to reduce joint stress
Moreover, worn suspension components or out-of-balance tyres can accelerate wear. If you're experiencing this issue, it may be time to buy new tyres online before they reach the tread wear limit.
To wrap things up…
A small part with a big responsibility, the track rod end plays a vital role in your car’s safety and steering performance. Whether you're preparing for your MOT or chasing down the source of that mysterious front-end clunk, don’t overlook this component.
Regular inspections, timely replacements, and proper alignment can save you from costly repairs and unsafe driving conditions. If you're not sure whether your track rod ends are due for replacement, it’s best to seek advice from a trusted mechanic or book an alignment check. If you’re repairing your car yourself, don’t forget to get a good set of steering tools to save you some hassle.
