Anti-roll bar

If there are signs of wear on the anti-roll bar in the area of the rubber bushings, then probably these have started to rotate. If this is the case, the rubber bushings must be replaced.

Shock absorbers

A special test machine is required for a full and proper check on the condition of the shock absorbers. Unless the noise comes from the rubber bushings for the shock absorber attachments a noisy shock absorber can be said to be used up and should be replaced. Small oil leakage can be accepted, but not in a drop form.
