Wheel Bearing: Service and Repair
REMOVE1. Raise vehicle on jackstands or centered on a frame contact type hoist.
2. Remove wheel and tire.
3. Remove brake drum from hub/bearing.
4. Remove rear wheel speed sensor from rear hub/bearing. This will prevent damage to the speed sensor during removal and installation of the hub/bearing. The rear wheel speed sensor bolts to the hub/bearing. It can not be removed unless the speed sensor is removed first.
CAUTION: When working in the area of the rear hub/bearing and when removing it from the rear axle, care must be used so the teeth on the tone wheel are not damaged. Damage to the teeth on the tone wheel will result in false ABS cycling and corrosion of the tone wheel.
5. Remove the 4 bolts attaching the hub/ bearing to the rear axle.
CAUTION: Corrosion may occur between the hub/ bearing and the axle. If this occurs the hub/bearing will be difficult to remove from the axle. If the hub/bearing will not come out of the axle by pulling on it by hand, do not Pound on the hub/bearing to remove it from the axle. Pounding on the hub/bearing to remove it from the axle will damage the hub/ bearing. This damage will result in noise or failure of the bearing.
6. If hub/bearing cannot be removed from the axle by hand, use Remover Special Tool 8214 or equivalent and following procedure to press the hub/bearing out of the axle.
a. Place Special Tool 8214-1 or equivalent over tone wheel and against cast flange of hub/bearing
b. Put a dab of grease in the bolt pilot hole on the back of Special Tool 8214-1 or equivalent.
c. Insert Special Tool 8214-2 or equivalent into the hole in the bottom of the end casting on the axle. Special Tool 8214-2 or equivalent should be against and supported by the axle plate when pressing the wheel bearing out of the axle. If Special Tool 8214-2 or equivalent will not fit into the hole in the end casting, file or grind the flashing from the hole until tool fits properly.
d. Align bolt in Special Tool 8214-2 or equivalent with pilot hole in Special Tool 8214-1 or equivalent. Tighten bolt against Special Tool 8214-1 or equivalent.
e. Press hub/bearing out of axle by continuing to tighten bolt in Special Tool 8214-2 against Special Tool 8214-1 or equivalents.
Removing Rear Hub/Bearing From Axle:
7. Remove the hub/bearing from the rear axle and brake support plate.
INSTALL
1. Install the 4 hub/bearing to axle mounting bolts into the holes in the flange of the rear axle.
2. Install the rear brake support plate on the 4 mounting bolts installed in the flange of the rear axle.
3. Align the rear hub/bearing with the 4 mounting bolts and start mounting bolts into hub/bearing. Tighten the 4 bolts in a criss-cross pattern until the hub/bearing and brake support plate is fully and squarely seated onto flange of rear axle.
4. Tighten the 4 hub/bearing mounting bolts to a torque of 129 Nm (95 ft. lbs.).
5. Install the rear wheel speed sensor on the rear hub/bearing flange. Install the speed sensor attaching bolt and tighten to a torque of 12 Nm (105 inch lbs.).
6. Install brake drum on hub/bearing.
7. Install wheel and tire.
8. Tighten the wheel stud nuts in the proper sequence to a torque of 129 Nm (95 ft. lbs.).
9. Adjust the rear brakes.
