Important:
The following information has also been updated within SI. If you are using a paper version of the Service Manual, please make a reference to this
bulletin on the affected page.
A number of front suspension lower control arms have been returned to the Warranty Parts Center (WPC). Input regarding these parts indicates
replacement corrected front suspension related clunk/rattle type noise concerns. Analysis of these returned components indicates that they were
manufactured to design intent and should have performed satisfactorily in the vehicle. It is recommended that when a front lower control arm is
suspected to be the cause of a front suspension noise concern, the technician perform the following fastener tightening procedure prior to control arm
replacement.
1.
Position the vehicle on a level surface at curb height (supported by the tires).
2.
Loosen the four lower control arm to front suspension crossmember attaching bolts.
