Condition Some customers may comment that a clunk noise can be heard from the rear suspension on moderate to severe jounce in cold temperatures approaching 0°F (−18°C).
Cause This may be caused by the rear suspension jounce bumpers becoming hard in cold temperatures, creating a feeling as though the suspension is bottoming out or a clunk noise may be heard.

 

Correction

If the jounce bumpers have been found the cause of the concern, the bumpers should be replaced with new bumpers that remain softer in colder temperatures.

 

Service Procedure

Refer to the Rear Spring, Insulator, and Jounce Bumper Replacement procedure in SI.
