Filing in context

Defect
On four-wheel-drive vehicles, the drive pinion lock nut in the rear axle differential was insufficiently staked against rotation. Repeated acceleration and deceleration cycles may cause the lock nut to loosen. As the lock nut loosens, the drive pinion contacts and damages the differential gear case, which may render the vehicle inoperable.
Corrective action
On all vehicles, inspect the lock nut for looseness. If the nut is secure, replace it with a conforming part. If looseness is found, replace the entire rear axle differential assembly with a conforming unit.
