After raising the vehicle and supporting it on jackstands, a jack should be positioned under the rear axle differential housing.

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

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

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

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.
