Find the source of a knock or bang
Tell us when the noise happens: over bumps, on a turn, when braking or at low speed. We inspect the suspension and steering, checking for wear, damage or movement.
A rattle can have more than one cause, so we identify the affected component before recommending replacement.
The parts we can assess and replace
Depending on the symptoms and inspection findings, work can include:
- Springs and shock absorbers.
- Suspension arms, bushes and ball joints.
- Anti-roll-bar links and track rod components.
- Wheel bearings and nearby components where the symptoms point towards them.
We explain what is worn and which work is urgent or can be planned.
Suspension and steering repair quotes
Quote after inspection
Your quote depends on the vehicle, parts and work needed. Call with your registration and symptoms so we can explain the assessment and agree the repair cost.

Steering and suspension work can affect wheel alignment. We can assess tracking and alignment requirements and discuss the appropriate work after replacement. Correcting alignment will not repair a worn joint, so the underlying condition needs attention first.
Why a worn joint can affect tyre wear
Suspension and steering components hold the wheels in their intended position as the car moves. Worn bushes, joints or damaged springs can alter that control and contribute to uneven wear, wandering or a knock.
An alignment adjustment cannot compensate for a component that moves excessively. We inspect the underlying condition first and explain the order of any repair and alignment work needed.
Describe the noise and the handling
A knock over a small bump, a hum that changes on a bend and a vibration at speed can point towards different areas. Tell us whether the steering wheel shakes, whether the car pulls and if the symptom began after a pothole impact. If a spring is visibly broken, a tyre is rubbing or the steering feels unsafe, stop driving and contact us to discuss the safest next step.
Frequently asked questions
Can you check a knocking noise?
Yes. A physical inspection is often the right starting point, even when there is no dashboard warning.
Do you replace track rod ends?
Yes. We inspect track rods and steering joints and quote for the parts and alignment work needed.
Will alignment stop uneven tyre wear?
It may help if alignment is the cause, but tyre condition and worn suspension components also need checking.
