INTRODUCTION: 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.
