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.

4WD models use a fully independent front axle assembly.

Before removing the rear axle assembly, the following components need to be removed: driveshaft, shock absorbers, vent hose, brake hose, rear brake assemblies, parking brake cables, and rear wheel speed sensors.

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.

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.

The differential allows the outer rear wheel to turn at a higher speed than the inner tire when going around a corner.

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

The next step is to drain the differential lubricant and remove the differential cover.

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 outer ends of the driveaxles are equipped with ball-and-cage type CV joints capable of angular but not axial movement.

The inner ends of the driveaxles are bolted to an axleshaft connected to the differential side gears.
