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

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

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

To install the rear axle assembly, the reverse order of removal should be followed. All suspension and brake fasteners should be tightened to the torque value specifications.

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

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

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

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.

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

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.
