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

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.

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

The final step is to tighten the wheel lug nuts to the proper torque specifications.

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

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.

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.

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

For coil spring models, the links for the electronic suspension control sensors should be detached, followed by detaching the track bar from the rear axle. The stabilizer bar, coil springs, and upper and lower trailing arms should be disconnected from the axle assembly. Finally, the jack can be lowered under the differential to remove the rear axle assembly.

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.

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

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.
