Removal

NOTE:
- Replacement of the rear hub/bearing is done without removing the rear knuckle or axle shaft from the vehicle.

- When removing the center cap from the wheel do not use a sharp or hard tool. Use of such a tool can damage the finish on the wheel and damage the center cap.





1. Remove the center cap from the wheel. Center cap is removed by inserting a trim stick into the notch on the center cap and prying it off the wheel.





2. With the weight of the vehicle supported by the tires and the parking brake applied, loosen hut do not remove the stub shaft to hub bearing nut.
3. Raise vehicle on jackstands or centered on a frame contact type hoist.
4. Remove the wheel and tire.





5. Remove the 2 bolts mounting the rear disc brake caliper to the caliper adapter.





6. Remove the disc brake caliper from the caliper adapter. Caliper is removed by first rotating the free end of the caliper away from the caliper adapter. Then with the free end of the caliper rotated away from the adapter, lift the caliper off the machined abutment on the adapter.





7. Support the disc brake caliper by hanging it from the shock absorber bracket on the flame rising wire or a tie strap. Do not let the flex hose support the weight of the brake caliper, damage to the flex hose can occur.

NOTE: If rotor retainers are on the wheel mounting studs they must be remove before attempting to remove rotor. They do not need to be installed when rotor is installed back on hub bearing.

8. Remove the rotor front the hub/bearing.





9. Remove the stub shaft to hub/bearing retaining nut.





10. Install Puller, Special Tool 6790, or equivalent on the flange of the hub/bearing. Place the bolt of the puller in the center of the stub shaft.





NOTE: The outer C/V joint needs to be pressed away from the knuckle for the required socket clearance when removing the hub/bearing mounting bolts.

CAUTION: When pressing the stub shaft out of the hub/bearing, do not exceed the distance of one inch from rear surface of the knuckle. If the stub shaft is pressed back further the driveshaft joints can be damaged.

11. Using Puller, Special Tool 6790, or equivalent partially press the stub axle out oft hub/bearing. The stub shaft is to be pressed out of the hub bearing until the rib on the C/V joint housing is one inch back from the real surface of the knuckle.

NOTE: Do not remove the 3 mounting bolts after they are threaded out of the hub bearing. The mounting bolts will hold the caliper adapter in position on the knuckle when the hub bearing is removed.

12. Unthread the 3 bolts, mounting the hub/bearing and caliper adapter to the knuckle, out of the hub/bearing mounting flange.

NOTE: The outer C/V joint stub axle spline to hub bearing spline are an interference fit. They can not be separated by hand. Puller, Special Tool 6790, or equivalent must be used to separate the hub bearing from the outer C/V joint stub axle.

13. Using Puller, Special Tool 6790, or equivalent continue pulling the hub/bearing off the stub shaft of the outer C/V joint until the 2 pieces separate. Then remove the hub/bearing from the outer C/V joint and caliper adapter.
