QuestionI want to replace the rear differential oil seal. Is all I have to do is remove the drive shaft, the nut behind it. And then pull out the oil seal and replace it ? If you can help, I would greatly appreciate it.Thanks
AnswerAXLE SHAFT
REMOVAL
Raise and support the vehicle.
Remove the wheel and tire.
Remove the brake drum.
Clean all the foreign material from housing cover area.
Loosen the housing cover bolts. Drain the lubricant from the housing and the axle shaft tubes. Remove the housing cover.
Rotate the differential case so that the pinion mate gear shaft lock screw is accessible. Remove the lock screw and the pinion mate gear shaft from the case Mate Shaft Lock Screw
Force the axle shaft in toward the center of the vehicle. Remove the axle shaft C - clip lock from the axle shaft Axle Shaft C - Clip Lock
Remove the axle shaft. Use care to prevent damage to the axle shaft bearing and seal, which will remain in the axle shaft tube.
Inspect axle shaft seal for leakage or damage.
Inspect the roller bearing contact surface on the axle shaft for signs of brinelling, galling and pitting.
If any of these conditions exist, the axle shaft and bearing or seal must be replaced.
INSTALLATION
Lubricate the bearing bore and seal lip with gear lubricant. Insert the axle shaft through the seal, bearing, and engage it with the side gear splines. Use care to prevent the shaft splines from damaging the axle shaft seal lip.
Insert the C - clip lock in the end of the axle shaft. Push the axle shaft outward to seat the C - clip lock in the side gear.
Insert the mate shaft into the case and through the thrust washers and pinion gears. Align the hole in shaft with the hole in the differential case and install the lock screw with Loctite® on the threads. Tighten the screw to 19 N·m (14 ft. lbs.) torque.
Install the cover and add fluid. Refer to the Drain and Refill in this section
