What causes the abnormal noise in Audi A3 shock absorbers?
1 Answers
Audi A3 shock absorber abnormal noise may be caused by the shock absorber itself leaking oil or bending, abnormal aging or wear of the shock pressure bearing, deformation of the shock spring, damage to the balance rod rubber sleeve, loose fixation of the shock absorber, or gaps in the connecting ball joint, etc. Deformation of the shock spring: Due to the structure of the vehicle's shock absorber, the entire shock absorber is compressed when the vehicle passes over bumpy roads, thereby compressing the external spring. However, after the vehicle passes the bumpy section, the spring's elasticity will reset the shock absorber. During the compression and resetting process of the shock absorber, a hissing or squeaking sound may accompany, which is a normal phenomenon. Any other abnormal noises from the shock absorber should also be taken seriously and addressed. Loose fixation of the shock absorber: Abnormal noise from the shock absorber can be caused by loose fixation, as long-term vibrations during driving can loosen the fixing nuts. Tightening the fixing nuts can solve this issue. Wear of the rubber bushings at both ends of the shock absorber can create play at the fixing points, causing noise during driving. Replacing the rubber bushings can eliminate the fault. Lack of oil in the shock absorber can also cause abnormal noise. Check for oil leakage; if there is no leakage, add the specified amount of shock absorber oil as required.
