To install a full-floating axle shaft, you should hold the axleshaft level to engage the splines and use a new gasket on the flange. Finally, tighten the flange bolts to the proper torque specifications.

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.

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.

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

Power is transmitted through a pair of driveaxles equipped with sliding constant velocity (CV) joints capable of both angular and axial motion.

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

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

After raising the vehicle and securing it on jackstands, you should pry off the hub cover and remove the driveaxle/hub nut while bracing the hub to prevent it from rotating.

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

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.

The optional locking limited-slip rear axle slows the rotation of the differential case when one wheel loses traction.
