2007 GMC TOPKICK 8500Transport Canada Recall #2007109
The official notice
Defect
On certain 7500 and 8500 series 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.
Safety Risk
No risk description available.
Remedy
Dealers will inspect and, if required, replace the axle assembly.
