Rear Suspension Spring Squeak/Creak (Lubricate Lower Spring Seat)

Some customers may comment on a squeak/creak noise coming from the rear of the vehicle when driving over an irregular/rough road surface at low speeds.

Slight surface irregularities on the mating surfaces of the rear springs and those on the lower spring seats of the rear strut assemblies may result in subtle movement. This may cause a squeak/creak noise when the rear suspension is subjected to certain types of road conditions. As component surfaces conform to one another, the noise typically goes away and is not apparent after a few hundred kilometers/miles of vehicle operation.

With the rear strut assemblies fully extended, lubricate the lower spring seats with GM Goodwrench™ Super Lube (P/N 12346241), or equivalent, between points indicated in the illustration.
