GM 15894423 Rear Wheel Bearing

Ensure the axle housing oil deflector is in position, then place the hub assembly on the axle tube without damaging the oil seals.

Attach a slide hammer to the puller and extract the bearing from the axle housing.

Pack the bearings with high-temperature front wheel bearing grease, ensuring it is forced between the rollers, cone, and cage. Apply a thin coat of grease to the spindle and place a small quantity inboard of each bearing race inside the hub.

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 further disassembly of the hub is necessary, it should be done.

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.

Tap it from side to side if necessary.

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.

Remove the brake disc and wheel speed sensor from the hub.

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

After discarding the oil seal, all components should be cleaned and inspected for wear or damage.
