Track rod end or ball joint
A ball joint or a stabiliser rod with play produces a knock on every uneven surface.
COMMON FAILURES01 02 03
Knocking over bumps
A sharp noise when going over a bump or a speed hump often comes from play in the suspension or the steering.
Possible causes
Shock absorber at end of life
A shock absorber that no longer damps the spring lets the body bounce and can cause a jolt at the end of travel.
Bushings and mounts
Cut or hardened rubber lets parts knock against each other, especially when cold.
Questions to ask the garage
- What play was measured, and on which part?
- Are the shock absorbers replaced in pairs?
- Is a wheel alignment planned after the work?
Indicative preliminary diagnosis. Does not replace a vehicle inspection by a professional.
