Before removing a semi-floating axle shaft, you should loosen the rear wheel lug nuts and raise the vehicle on jackstands.

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.

The initial steps are to loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands.

The vehicle has a hypoid, semi-floating type rear axle assembly.

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

To remove and install components in the front differential for AWD systems, follow these steps: Remove the stabilizer bar link and, if applicable, the front shock absorber. Unbolt the right driveaxle from the axleshaft flange, supporting it properly. Support the differential carrier with a floor jack and a block of wood. Remove nuts attaching the axle shaft to its support bracket and the bolts securing the axle shaft flange to the differential carrier. Use a brass punch and hammer to separate the axle shaft from the differential case side gear. Remove the inner axle shaft assembly and axle shaft. Replace the inner seal and bearing with a special tool, then apply RTV sealant to the differential sealing surface and install the inner axle shaft housing assembly. Install the axle shaft to the support bracket and align the splines with the differential side gear. Tap the axle shaft with a mallet until the ring (clip) aligns with the groove in the differential case side gear. Install the axle shaft to the inner flange and tighten the bolts. Reinstall the stabilizer link, fill the differential with lubricant, install the differential carrier splash shield, and finally, install the wheel and lug nuts. Lower the vehicle, tighten the lug nuts, and check for proper operation.

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.

The initial steps to remove and install components in the front differential of selectable 4WD systems are as follows:Loosen the wheel lug nuts.

After removing the differential cover, you need to remove the pinion shaft lock screw and withdraw the pinion shaft.

To check for wear in the CV joints and driveaxle shafts, grasp each axle and rotate it in both directions while holding the CV joint housings, feeling for play indicating worn splines or sloppy CV joints.

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.

To remove the rear axle assembly from a vehicle, first loosen the rear wheel lug nuts, raise the rear of the vehicle, and support it securely on jackstands. Then, position a jack under the rear axle differential housing and remove the driveshaft, shock absorbers, vent hose, brake hose, rear brake assemblies, parking brake cables, and rear wheel speed sensors. For leaf spring models, disconnect the spring U-bolts and remove the springplates before lowering the jack under the differential and removing the rear axle assembly. For coil spring models, detach the links for the electronic suspension control sensors, detach the track bar from the rear axle, remove the stabilizer bar, remove the coil springs, and disconnect the upper and lower trailing arms from the axle assembly before lowering the jack under the differential and removing the rear axle assembly. To install the rear axle assembly, follow the reverse order of removal and tighten all suspension and brake fasteners to the torque value specifications. Finally, bleed the brakes, install the wheels and lug nuts, lower the vehicle, and tighten the lug nuts to the proper torque specification.

The drive axle-to-axle shaft flange bolts should be removed while having an assistant apply the brake to prevent the driveaxle from turning.

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

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

Yes, there is an optional locking limited-slip rear axle available.

The outer ends of the driveaxles have a stub shaft that is splined to the front hub and bearing assembly and locked in place with a large nut.

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.

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.

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.

If the vehicle has a differential carrier splash shield, it should be removed after removing the driveaxle/hub nut.

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

The initial steps are to loosen the rear wheel lug nuts, raise the rear of the vehicle, and support it securely on jackstands.

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