Service bulletin 05-70-19

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.

NHTSA's summary

This bulletin announces a design change made to the rear wheel / brake backing plates. Under certain circumstances, some customers may have a concern regarding a howling-type sound from the rear of the vehicle later diagnosed as a faulty hub / bearing assembly. Unevenness of the backing plate surfaces may affect the concentricity (roundness) of the hub / bearing after torqued during assembly and over time, cause the howling -type sound to develop. Production changes for the backing plates have been implemented to optimize their mounting surface quality.
