To remove the semi-floating axle shaft, you need to remove the C-lock from the groove on the inner end of the axleshaft and withdraw the shaft, being careful not to damage the oil seal.

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

For leaf spring models, the spring U-bolts should be disconnected, followed by removing the springplates. Then, the jack can be lowered under the differential to remove the rear axle assembly.

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.
