Condition
Some customers may comment on a rattle, clunk, pop, loose lumber-type noise coming from the front and/or rear suspension while driving over rough
uneven roads.
Cause
The front and/or rear stabilizer links, may develop additional clearance in the ball joint links leading to a noise concern.
Correction
1.
Road test the vehicle and verify if the noise is coming from the front or rear, left or right of the vehicle. It is possible in some circumstances that
the noise may be coming from the front and rear suspension.
2.
Once it is determined that the noise is coming from the front or rear, left or right of the vehicle, raise the vehicle on a hoist. Refer to Lifting and
Jacking the Vehicle in General Information (SI Document ID # 1253321).
Caution:
DO NOT DRIVE the vehicle on highways or at a high rate of speed while the stabilizer link(s) are removed/disconnected from the vehicle.
ONLY test drive the vehicle in a parking lot or on a side street. Driving the vehicle with the link(s) removed/disconnected may reduce vehicle
stability.
3.
Remove or disconnect the suspect stabilizer link(s) from the appropriate stabilizer shaft and re-road test the vehicle with the links disconnected to
verify the source of the noise.

If the noise is still present with the suspect link(s) removed the source of the noise is NOT the stabilizer links. Refer to the information below
