Track rod ends are a major MOT steering and safety check in the UK. Excessive play, damaged rubber boots, corrosion or insecure steering joints can quickly become dangerous and lead to MOT failure.
A track rod end can fail an MOT if the joint is worn, loose, damaged, insecure or has excessive movement. Steering components must be secure and operate safely.
If your car knocks when steering, wanders on the road, wears tyres unevenly or feels vague through the steering wheel, it should be checked before the MOT.
The tester is checking for play, security, damage and dust boot condition. A track rod end should not have excessive movement, should be fixed securely, and should not have a boot defect that exposes the joint to contamination.
These are the practical points that matter during the steering and suspension inspection.
The joint should not have looseness beyond safe limits. Excessive play can affect steering accuracy.
A split or missing boot can let water and dirt into the joint, causing rapid wear.
Loose fixings, loose lock nuts or insecure components can make the steering unsafe.
The ball joint inside the track rod end should move correctly without looseness.
Bent, cracked or heavily corroded parts may be unsafe.
Any defect affecting control of the vehicle is treated seriously.
These are the faults that can turn into an MOT failure.
Movement in the joint beyond safe limits can fail because it affects steering control.
Loose lock nuts or insecure fixing points are unsafe and should be repaired before the test.
A damaged rubber boot can allow dirt and water into the joint and may cause MOT failure.
Internal wear can reduce steering precision and safety.
Bent, cracked or heavily corroded parts may fail.
Any defect affecting control of the vehicle is serious.
These symptoms can also come from other steering or suspension faults, so proper inspection matters.
Often noticed at low speed, during parking or when changing direction.
The steering may feel loose, delayed or less precise than usual.
Worn joints can affect alignment and cause inner or outer shoulder tyre wear.
Tyre tread MOT guide →Worn steering joints can contribute to vibration, especially with tyre or wheel issues.
Steering shake guide →Worn steering joints may affect alignment and straight-line stability.
Pulling guide →Front-end looseness may be noticeable over potholes, rough roads or speed bumps.
Yes, it can. The rubber dust boot protects the joint grease and keeps dirt and moisture out. If it splits, the joint can wear quickly and may already be contaminated.
A boot defect becomes more serious if grease has escaped, dirt has entered or the joint already has movement.
Once the boot is split, water and road grit can get into the joint. That turns a small rubber problem into a worn steering joint.
If the joint has play as well as a split boot, replacement is normally the sensible repair.
These checks can help you spot signs of track rod end wear before test day.
Listen for knocks while turning the steering at low speed or parking.
Look for uneven inner or outer shoulder wear on the front tyres.
If the car needs constant correction to stay straight, get the steering checked.
If safe to do so, check the rubber dust boots for tears, grease loss or damage.
A steering wheel that sits off-centre can point to alignment or steering component issues.
A garage can check track rod ends, inner joints, ball joints and lower arms properly on a ramp.
Yes, if there is play, knocking, split boots or vague steering. Track rod ends are common wear items and directly affect steering safety.
Leaving a worn track rod end can make tyre wear worse and may make the vehicle less predictable on the road.
Yes, wheel alignment is usually recommended after track rod end replacement. The track rod affects toe angle, so replacing or adjusting it can change the steering geometry.
Skipping alignment can lead to off-centre steering and rapid tyre wear.
Wheel alignment MOT guide →Costs vary depending on access, parts quality, seized threads and whether alignment is included.
Often moderate cost depending on vehicle and labour time.
May be sensible if both joints are similarly worn or the car has high mileage.
Usually recommended after steering component replacement.
Rusty or seized track rod threads can add labour time.
Sometimes the inner tie rod or steering rack joint is worn too.
If the fault has caused severe tyre wear, tyres may also need replacing.
Track rod end wear can feel similar to steering rack play, inner tie rod wear, lower arm bushes or ball joint faults. Correct diagnosis helps avoid replacing the wrong parts.
A proper ramp inspection can show whether the play is in the outer joint, inner joint, rack, lower arm or ball joint.
Uneven front tyre wear, an off-centre steering wheel, pulling, knocking or recent MOT advisories for steering joints are all signs to check carefully.
A fresh MOT does not always mean steering parts are perfect for the next year.
Used car inspection checklist →These are common situations seen during MOT preparation and steering diagnosis.
The tyre can look fine from outside while the inner edge is wearing badly.
A steering joint can knock like a suspension bush or drop link.
A split boot may not make noise at first, but the joint can wear quickly once contaminated.
This can happen after kerb impact, worn joints or poor alignment.
Old track rod ends can be harder to adjust or replace if threads are rusty.
Sometimes one side is clearly worn, but the other side should still be checked.
Common questions about worn track rod ends, split boots, tyre wear and alignment.
Yes, if there is excessive play or unsafe wear.
It can, especially if the joint is contaminated, grease has escaped or the joint is worn.
Yes, worn joints can affect wheel alignment and cause uneven tyre wear.
Usually yes, it is strongly recommended.
It depends on severity, but steering faults should be repaired quickly.
Yes. A worn track rod end can knock when turning, driving over bumps or changing direction.
Yes. Track rod wear or adjustment can leave the steering wheel off-centre.
Have any steering knock, looseness or uneven tyre wear inspected before MOT.
