Loosen the rear wheel lug nuts and raise the rear of the vehicle. Support it securely on jackstands and block the front wheels. Remove the wheel and brake drum. Remove the differential cover and allow the lubricant to drain into a container. Remove the lock bolt. On models with a conventional differential, remove the pinion shaft. On models with a locking differential, withdraw the pinion shaft part way, then rotate the differential until the shaft touches the case. Have an assistant push in on the outer flanged end of the axleshaft while you remove the C-lock from the groove in the inner end of the shaft. With the C-lock removed, withdraw the axleshaft, taking care not to damage the oil seal. Some models have a thrust washer in the differential; make sure it doesn't fall out when the axleshaft is removed. To install, carefully insert the axleshaft into the housing and seat it securely in the differential. 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. Check the cover gasket and replace if necessary. Install the cover and tighten the bolts. Fill the differential with the specified lubricant. Install the brake drum, wheel, and lug nuts. Lower the vehicle and tighten the lug nuts.

Take care not to damage the oil seal and ensure that the thrust washer in the differential doesn't fall out.

If tapping the stub shaft with a hammer doesn't free it from the hub splines, you can push the driveaxle from the hub with a puller.

Factors like road noise, tire conditions, and engine or transmission noise should be thoroughly checked as they may mimic axle problems.

The initial steps include loosening the rear wheel lug nuts, raising the rear of the vehicle, supporting it securely on jackstands placed under the frame rails, and blocking the front wheels to prevent the vehicle from rolling off the stands.

Common symptoms of worn or damaged CV joints include a clicking noise in turns, a clunk when accelerating after coasting, and vibration at highway speeds.

After unbolting the brake hose retainer, the next step is to remove the steering knuckle and simultaneously pull the driveaxle stub shaft out of the hub.

The axleshafts are splined to the differential side gears, allowing for speed difference.

The inner ends of the driveaxles are splined to the differential side gears.

Before removing the rear axle assembly from under the vehicle, you should disconnect the shock absorbers at their lower mounts, disconnect the vent hose from the fitting on the axle housing, and disconnect the flexible brake hose from the junction block on the axle housing (and plug the hose to prevent fluid leakage).
