The hazard
On certain trucks, the rear drive axle housing was manufactured with steel below the specified thickness, which could result in fatigue failure over time. If failure occurs, the outboard end of the housing could eventually separate, allowing the hub, axle shaft, and/or wheel and brake assembly to separate from the vehicle. This could cause a vehicle crash with injury or death. Correction: Dealers will inspect and, if required, replace the axle assembly.
