Rear Hub And Bearing - Installation

ALL-WHEEL-DRIVE

Special Tools:










1. With the brake shield in place on the knuckle, slide the hub and bearing over the axle half shaft and position it on the knuckle.
2. Install the four bolts (1) securing the hub and bearing to the knuckle. Tighten the bolts to 60 Nm (44 ft. lbs.).






CAUTION: Ensure that sensor mounting surface on bearing is clean before sensor installation.

3. Pass the wheel speed sensor head (2) through the hole in the brake shield, then push it into the mounting hole in hub and bearing (1) and align the mounting screw hole.
4. Install a NEW mounting screw (2). Tighten the mounting screw to 6 Nm (55 in. lbs.).





5. Clean the rotor mounting face of the hub and bearing (1) to remove any dirt or corrosion.
6. Install the brake rotor (2) over the hub and bearing (1).

CAUTION: If the brake rotor or brake pads are being replaced, the rear caliper piston must be seated (bottomed) to compensate for the new brake rotor or lining. Because the parking brake self-adjuster mechanism is attached to the piston, a special seating method is required. The only acceptable method is by rotating the piston back into the bore using Retractor, Special Tool , as described below. Any other seating method will damage the self-adjuster mechanism.





7. If necessary, seat (bottom) the caliper piston in the bore as follows:
a. Assemble a 3/8 in. drive ratchet handle and an extension (3).
b. Insert the extension through Special Tool (2).
c. Place Special Tool (1) on the end of the extension.
d. Insert lugs on Special Tool into notches in face of caliper piston (5).
e. Thread the screw drive on down until it contacts the top of which is against the caliper piston. Do not over tighten the screw-drive. Damage to the piston can occur.
f. Turn with the ratchet, rotating the piston in a clockwise direction until fully seated (bottomed) in the bore. It may be necessary to turn with to start the process of piston retraction.





8. Install the disc brake caliper and adapter bracket (2) over the knuckle and rotor as an assembly.
9. Install the two bolts (1) securing the disc brake caliper and adapter bracket (2) to the knuckle. Tighten the mounting bolts to 100 Nm (74 ft. lbs.).






NOTE: Always install a new hub nut. The original hub nut is one-time use only and should be discarded when removed.

10. Clean all foreign matter from the threads of the half shaft outer C/V joint.
11. Install the washer (4) and hub nut (3) on the end of the half shaft and snug it.
12. While a helper applies the brakes to keep the hub (1) from rotating, tighten the hub nut (3) to 245 Nm (181 ft. lbs.).
13. Insert the cotter pin (2) through the notches in the nut and the hole in half shaft. If the notches in the nut do not line up with the hole in the half shaft, continue to tighten the nut until they do. Do not loosen the nut.
14. Wrap the cotter pin (2) ends tightly around the lock nut.





15. Install tire and wheel assembly (1) . Tires And Wheels - Installation Install and tighten wheel mounting nuts (3) to 135 Nm (100 ft. lbs.).
16. Lower the vehicle.
17. Pump the brake pedal several times to ensure the vehicle has a firm brake pedal before moving it. Check the brake fluid level.
