Loosen the wheel lug nuts before removing the axle shaft of a vehicle. Start by loosening the wheel lug nuts, driving it up to jack stands, and securely supporting it on jackstands. Pry off the hub cover and remove the axle shaft/hub nut, bracing the hub to prevent it from rotating. Remove differential carrier splash shield if equipped and then remove axle shaft-to-axle shaft flange bolts (while having an assistant apply the brake to stop axle shaft from turning). Drop inner end of axle shaft low enough in order to pull stub shaft out of hub, guiding carefully under car as you take out entire axle shaft with other hand. To install an axle shaft , lubricate splines on stubshaft with multipurpose grease then tighten axleshaft/ hub nut (new) and flange bolts according to specified torque values. Then finally fasten wheels using appropriate torque specification for lug nuts.

The initial steps to remove and install components in the front differential of selectable 4WD systems are as follows: Loosen the wheel lug nuts. Raise the vehicle securely on jackstands. Remove the right front wheel. Remove the differential carrier splash shield if equipped. Drain the lubricant from the front differential. For 4WD systems, unbolt the right driveaxle from the axleshaft flange and support it out of the way. Remove the front axle shift motor and, if applicable, disconnect the front stabilizer link or remove the front shock absorber/coil spring assembly. On 2500/3500 models, remove the front axle bracket bolts and slide the bracket forward for additional clearance. Support the differential carrier with a floor jack and a block of wood.

To install the rear axle assembly, the reverse order of removal should be followed. All suspension and brake fasteners should be tightened to the torque value specifications.

The differential allows the outer rear wheel to turn at a higher speed than the inner tire when going around a corner.

If a boot is damaged, the CV joint can be disassembled and cleaned, but if any parts are damaged, the entire driveaxle assembly must be replaced as a unit.

The next step is to drain the differential lubricant and remove the differential cover.

In 4WD models, an extension axle shaft is used on the right side to make up the difference in distance between the differential and the right front wheel.

For models with a locking differential, you should rotate the differential until the shaft touches the case for access to the C-locks.

After installing the rear axle assembly, the brakes should be bled, the wheels and lug nuts should be installed, and the vehicle should be lowered. Finally, the lug nuts should be tightened to the proper torque specification.

No, overhauling the differential requires special tools and is not cost-effective for a do-it-yourselfer.

Symptoms of worn or damaged CV joints include lubricant leaks, clicking noise in turns, clunk when accelerating after coasting, and vibration at highway speeds.

Before installing the driveaxle, the splines on the stub shaft should be lubricated with multi-purpose grease.

The inner end of the driveaxle should be lowered and pulled out of the hub, carefully guiding the driveaxle out from under the vehicle.

After installing the rear axle assembly, the brakes should be bled, the wheels and lug nuts should be installed, and the vehicle should be lowered. Finally, the lug nuts should be tightened to the proper torque specification.

The outer ends of the driveaxles are equipped with ball-and-cage type CV joints capable of angular but not axial movement.

To remove a full-floating axle shaft, you need to remove the bolts attaching the flange to the hub and withdraw the shaft from the housing.

It is important to inspect the boots periodically for damage and leaking lubricant, as torn CV joint boots must be replaced immediately to prevent damage to the joints.

The inner end of the driveaxle should be lowered and pulled out of the hub, carefully guiding the driveaxle out from under the vehicle.

To remove and install components in the front differential for 4WD systems, follow these steps: Remove the bolts securing the axle tube to the differential carrier and the nuts attaching the tube to its support bracket. Carefully remove the output shaft tube, ensuring no components fall out. Mount the tube in a vise and remove the internal components. Measure and remove the axleshaft bearing using a slide hammer and bearing remover attachment. For installation, install the bearing to the original depth using a bearing driver or socket, then install a new seal and deflector, lubricating the seal lips with grease. Carefully drive in the axleshaft, followed by the internal components. Apply RTV sealant to the tube-to-differential housing mating surface, and install the tube assembly, tightening bolts and nuts to specified torques. Reinstall the driveaxle, front axle shift motor, and fill the differential with lubricant.

The differential allows the outer rear wheel to turn at a higher speed than the inner tire when going around a corner.

To install the semi-floating axle shaft, you should insert the axleshaft into the housing until it engages with the differential side gear, install the C-lock, and insert the pinion shaft. Then, install the cover, fill the differential with lubricant, and install the brake disc or drum.

Before removing the rear axle assembly, the following components need to be removed: driveshaft, shock absorbers, vent hose, brake hose, rear brake assemblies, parking brake cables, and rear wheel speed sensors.
