Defect
On certain vehicles, the lug nuts could potentially bottom out on the shoulder of the studs when used in a single rear wheel application. If this occurs, there could be inadequate clamp load to attach the wheel to the axle. This could potentially result in loss of a rear wheel while the vehicle is being driven.
Safety Risk
No risk description available.
Remedy
Rear wheel attaching studs will be replaced with a revised stud having a different profile that precludes the interference with the lug nuts.
