This bulletin is being revised to end the need for information from the field and to provide engineering recommendations to correct the concern. Please discard Corporate Bulletin Number 07-03-09-001I (Section 03 - Suspension).
Condition
Some customers may comment on a creak, pop, or clunk noise coming from the rear of the vehicle.
Cause
This condition may be caused by the rear strut spring rubber isolator contacting the lower spring coil.
Correction
Engineering has made the following recommendation to eliminate this concern.
1. Raise and support the vehicle.
2. Through the rear wheelhouse opening, locate the lower first four rubber isolator tabs.
3. Using an utility knife, cut the four tabs flush with the surface of the isolator. Be careful not to cut all the way through the rubber isolator to the metal spring coil.
4. Apply lubricant, GM P/N 12345996 (in Canada, use P/N 10953501), or equivalent, to the lower spring coil. Cover the entire area under the removed tabs.
5. Repeat the above steps for the opposite side.
6. Lower the vehicle.
