Install the bearing with the square shoulder facing in, using a bearing driver or a socket with an outside diameter slightly smaller than that of the bearing.

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.

The hub assembly can be removed from the axle tube by using a special socket to remove the adjusting nut and pulling the hub assembly straight off the axle tube.

After removing the axleshaft and rear wheels, the brake disc and retaining ring/key should be removed from the end of the axle housing.

To remove the hub assembly from a vehicle, first loosen the front wheel lug nuts and raise the vehicle on jackstands. Remove the wheel and, if working on a 4WD model, remove the hub cover and unscrew the driveaxle/hub nut with a socket and large breaker bar. Remove the brake disc and wheel speed sensor from the hub, then remove the hub retaining bolts from the steering knuckle and remove the disc shield. Finally, remove the hub from the steering knuckle, tapping it from side to side if necessary. To install a new hub assembly, clean the mating surfaces on the steering knuckle, bearing flange, and knuckle bore. Insert the hub and bearing assembly into the steering knuckle and, on 4WD models, onto the end of the driveaxle. Install the wheel speed sensor, brake disc, caliper mounting bracket, and caliper. On 4WD models, install the driveaxle/hub nut and tighten it to the torque specifications. Finally, install the wheel, lower the vehicle, and tighten the lug nuts to the torque specifications.

1. Install the bearing with the square shoulder facing in, using a bearing driver or a socket with an outside diameter slightly smaller than that of the bearing. 2. Install a new seal and deflector, lubricating the lips of the seal with multi-purpose grease. 3. Carefully drive in the axle shaft with a soft-face hammer. 4. Fill the differential with the proper lubricant. 5. Install the driveaxle and differential carrier splash shield. 6. Install the wheel and lug nuts. 7. Lower the vehicle. 8. Tighten the lug nuts to the proper torque specifications. 9. Check for proper operation.

The first step is to remove the axleshaft and oil seal.

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.

After removing the hub assembly, the oil seal should be discarded.

The old bearing can be extracted from the housing using a bearing puller and slide hammer.

The hub assembly can be removed from the axle tube by using a special socket to remove the adjusting nut and pulling the hub assembly straight off the axle tube.

The new bearing can be installed using a bearing installer or a piece of pipe against the outer race.

Remove the hub retaining bolts from the steering knuckle and remove the disc shield.

The hub assembly can be removed from the axle tube by using a special socket to remove the adjusting nut and pulling the hub assembly straight off the axle tube.

After adjusting the bearings, the key and retaining ring should be installed.

Remove the hub retaining bolts from the steering knuckle and remove the disc shield.

1. Loosen the wheel lug nuts. 2. Raise the vehicle. 3. Place it securely on jackstands. 4. Remove the left front wheel. 5. Remove the differential carrier splash shield from under the front axle. 6. Remove the left driveaxle. 7. Drain the lubricant from the front differential. 8. Pull the left axle shaft out with a slide hammer and adapter. 9. Remove the deflector and seal from the differential. 10. Remove the bearing using a slide hammer and bearing remover attachment.

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.
