Squeak Noise From Rear Suspension
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.
Figure 1.
HINT
Applying soapy water to the suspected
bushing may temporarily diminish the
noise intensity and help identify the source
of the noise.
