Abnormal Squeak Noise From Rear Suspension Over Uneven Roads
Repair Procedure
1. Confirm the condition exists.
Using ChassisEAR™ (or equivalent), test drive the vehicle over an uneven road surface, such
as a sloped driveway, to verify the condition is coming from the bushings.
HINT
Applying soapy water to the suspected bushing may temporarily diminish the noise intensity and
help identify the source of the noise.
Is a squeak noise present?
YES — Continue to step 2.
NO — This bulletin does NOT apply. Continue diagnosis using the applicable
Repair Manual.
2. BEFORE installing NEW parts, confirm the identification mark as shown. If this mark is NOT
present, the part is incorrect and SHOULD NOT BE INSTALLED.
NOTE
The identification mark on the NEW part faces the outside of the vehicle.
