Release the parking brake, raise the rear of the vehicle, support it securely on jackstands, and block the front wheels before removing the wheels and tires. Next, remove the brake drum and the ABS sensor, then disconnect the parking brake cables from the brake shoe and backing plate, followed by the removal of the brake shoes. Drain the brake fluid and remove the brake lines from the wheel cylinders, then take out the four backing plate mounting nuts to detach the axleshaft from the rear axle housing. Carefully pull the axleshaft out of the rear axle housing along with the backing plate, ensuring not to damage the axleshaft seal. Remove the O-ring from the rear axle housing and the axleshaft inner oil seal using a seal removal tool or a big screwdriver. If further disassembly of the axleshaft assembly is needed, special tools and a hydraulic press will be required; for replacement of the axleshaft, bearing, or outer oil seal, take the assembly to an automotive machine shop. Drive a new axleshaft inner seal into the end of the axle tube with a seal installer or a big socket, coating the lip of the seal with clean oil or multi-purpose grease. Install a new axle housing O-ring, applying a light coat of oil to it. Ensure the axleshaft is clean and free of burrs or metal splinters, deburring any surface irregularities to prevent damage to the seal during installation. Lightly coat the axleshaft with clean oil, then insert it into the axle housing, taking care not to damage the lip of the new axleshaft seal. Finally, installation is the reverse of removal, and the four backing plate mounting nuts should be tightened to the specified torque.

Installation is the reverse of removal. Be sure to tighten the driveaxle/hub nut to the specified torque, then install the nut lock and a new cotter pin. Tighten the lug nuts and all suspension fasteners to the specified torque.

Position a floor jack under the rear axle differential housing.

Wrap the splines on the inner end of the axleshaft with electrical or duct tape to protect the boots from the sharp edges of the splines.

Some models are equipped with an electronic locking rear differential.
