Before removing a semi-floating axle shaft, you should loosen the rear wheel lug nuts and raise the vehicle on jackstands.

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

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

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

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

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 initial steps to remove and install components in the front differential of selectable 4WD systems are as follows: Loosen the wheel lug nuts. Raise the vehicle securely on jackstands. Remove the right front wheel. Remove the differential carrier splash shield if equipped. Drain the lubricant from the front differential. For 4WD systems, unbolt the right driveaxle from the axleshaft flange and support it out of the way. Remove the front axle shift motor and, if applicable, disconnect the front stabilizer link or remove the front shock absorber/coil spring assembly. On 2500/3500 models, remove the front axle bracket bolts and slide the bracket forward for additional clearance. Support the differential carrier with a floor jack and a block of wood.

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

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.

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.

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.

The drive axle-to-axle shaft flange bolts should be removed while having an assistant apply the brake to prevent the driveaxle from turning.
