Customer states:

Rumbling or squeaking noises from the front end.

Workshop findings:

The buffer stops of the shock absorbers are identified as the source of the noise because they do not sit correctly in the shock absorber mounting (Figure 1).

TECHNICAL BACKGROUND

New improvements were made in the suspension design and the material in the buffer stop was changed to increase the hardness. As a result, it has become harder to press them into the mountings.

PRODUCTION SOLUTION

Not applicable.

SERVICE

Secure the buffer stops correctly. A tire assembly paste can be used as an aid. The buffer stops must be completely pressed in.
If the buffer stops were deformed during the vehicle transport, try to shape them correctly by warming them up slightly. If this is not possible, replace the affected components.
