The problem
The locking screw that retains the pinion shaft in place in the differential could come loose. The pinion shaft turns the gears inside the differential that rotate the drive axles and rear wheels. If the locking screw comes loose, it could damage other components or jam in the gears. If the pinion shaft comes loose, the rear wheels may no longer power the vehicle.
The fix
The dealer will replace the differential lock screw at no charge.
