DESCRIPTION
Some vehicles may experience one or both of the following noises from the front shock absorber.


A knocking/popping noise occurs when passing over speed bumps.
A squeaking noise occurs when turning the steering wheel with vehicle at a standstill or at low
speed.
This is caused by the bump stopper (2) contacting the strut bearing (3) when the front shock absorber (1) is
compressed.
To eliminate this concern, the shape of the bump stopper has been modified.

Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify concern.
2. Check to see if the noise is coming from the front shock absorber(s).


If the noise is coming from the front shock absorber(s), go to the next step.
If the noise is not coming from the front shock absorber(s), this TSB does not apply.
3. Replace the bump stopper (both sides) with a modified one according to instructions on MGSS (FRONT
SHOCK ABSORBER AND COIL SPRING DISASSEMBLY/ASSEMBLY).
NOTE:Before removing the mounting rubber, put a position mark on it and the shock absorber so the
mounting rubber can be installed back in the original position.
CAUTION:It is not necessary to adjust the front wheel alignment because the front shock absorber and the
mounting rubber are not replaced. However, make sure to install the mounting rubber to the original
position.
4. Apply approx. 3 - 5 gram of rubber grease on the hatched areas as shown (all the way around).
NOTE:DO NOT apply grease on the threads (1).
