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.

4WD models use a fully independent front axle assembly.

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

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

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

Before installing the driveaxle, the splines on the stub shaft should be lubricated with multi-purpose grease.

The outer ends of the driveaxles have a stub shaft that is splined to the front hub and bearing assembly and locked in place with a large nut.

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

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

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

It is important to inspect the boots periodically for damage and leaking lubricant, as torn CV joint boots must be replaced immediately to prevent damage to the joints.
