Inspection (Noises)

Shock absorbers are often replaced because of rattling noises. Tests on the test stands and on vehicles have determined that for about 70% of the shock absorber complaints there was no problem and replacement was not necessary. Proceed as follows for complaints which are interpreted as rattling or cracking noises. Determine where, when and how noises develop during a road test with the customer. If possible, road test vehicle on a dry, uneven driving surface.

Malfunctioning shock absorbers are noticeable during driving due to loud rattling noises caused by wheel bouncing, particularly on rough driving surfaces. They can also be externally identified by large oil loss.
