Defect
In the power transmission system, the lock nut securing the bevel pinion bearing in the front wheel differential was tightened with insufficient torque and improperly staked to prevent rotation. Continued use allows the lock nut to loosen, producing abnormal noise. In the worst case, the bevel pinion fractures, eliminating braking force to the front wheels and reducing overall braking performance.
Corrective action
On all vehicles, replace the lock nut with a new part. If any signs of loosening are found during replacement, inspect the bevel pinion, bevel gear, and bearing for damage and replace any damaged components with new parts.
