Service bulletin sb32-054

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

This can result in cracking at the transverse rod tower where it is welded to the axle housing, premature wearing of the transverse torque rod tapered pin and bushings, and damage to the transverse torque rod frame bracket.
