To start the process of removing the rear differential, lift the rear of the vehicle and support it securely using jackstands. Take off the wheel as well as brake drum. If there is a locking differential on that vehicle, remove both rear wheels and brake drums. Remove the cover of your differential to let the oil drain into a pan. For traditional differentials, take out pinion shaft by extracting lock bolt. Using an assistant push in on an outer flanged end of an axle shaft while removing any c-lock from groove inside opposite end of a shaft. Turn over such a differential so that you can gain access and support its pinion shaft in order to avoid it falling down into case when working on locking type differentials. Partially withdraw your pinion shaft by taking out its lock bolt and rotating this type of differential until a shaft touches case allowing enough space for clearing out to c-locks. Use screwdriver for twisting c-lock until open endpoints are aligned then insert axleshaft back in then remove c-lock which is compressed at this time, repeat procedure with another axleshaft also with C-Lock no longer in place carefully pullout axleshaft because it may damage oil seal if not taken with great care some models may have a thrust washer in diff make sure it doesn't fall out when removing axle shaft next, take care inserting this part into housing so that it seats properly inside differential always used on typical differentials putting lock on flange must be used to achieve this result put C-Lock back into groove on axle shaft slide backwards using correct positioning after installing C-locks after withdrawing axleshafts slowly until C-Lock clears thrust block now that c-locks are installed push pinion shat through position where hole lines up with lock bold hole then install lock bolt at last install cover and fill diff with specified lubricants reinstalling brake drums and wheels followed by lowering car.

The differential is housed within a casting known as the "carrier," which has a pressed steel cover. The steel axle tubes are pressed into and welded to the carrier.

Disconnect the driveshaft and secure it out of the way.

A prybar or large screwdriver can be used to hold the driveaxle.

For locking differentials, rotate the differential for access and support the pinion shaft to prevent it from falling into the case. Remove the lock bolt and withdraw the pinion shaft part-way.

Remove the steering knuckle.

Reverse the removal steps and make sure to lower the vehicle weight onto the wheels before tightening the U-bolt nuts completely.

The rear axle assembly is a hypoid, semi-floating type with a differential. Its purpose is to allow the outer rear tire to turn more quickly than the inner tire when the vehicle goes around a corner, ensuring smooth handling.

Start by loosening the rear wheel lug nuts and raising the rear of the vehicle with jackstands placed under the frame.

Overhauling the differential may require special tools, and it is not typically cost-effective for a do-it-yourselfer. Professional expertise and equipment are often needed for this type of work.

Carefully insert the axleshaft into the housing and seat it securely in the differential.

Remove the nut and washer.

The driveaxles are retained by snap rings at the inner end of the tri-pot joints.

If applicable, disconnect the vent hose and brake hose.

For conventional differentials, install the C-lock in the axleshaft groove and pull out on the flange to lock it. Insert the pinion shaft, align the hole in the shaft with the lock bolt hole, and install the lock bolt.
