19. Remove the hub/bearing (Fig. 140).

Fig. 141 Hub/Bearing Removal From Caliper Adapter:

CAUTION: Corrosion may occur between the hub/ bearing and the axle flange. If this occurs, the hub/ bearing will be difficult to remove from the axle and disc brake caliper adapter. If the hub/bearing will not come out by pulling on it by hand, don't not pound on it with a hammer. Pounding on the hub/ bearing will damage it. To remove a hub/bearing that is corroded in place, lightly tap the disc brake caliper adapter using a soft-face hammer. This will remove both the caliper adapter and hub/bearing together from the axle. With a helper supporting the caliper adapter in his hands, position Remover, Special Tool 8214-1, on the cast housing of hub/ bearing (Fig. 141). Do not position the special tool on the inner race of hub/bearing. Lightly strike the Remover with a hammer to remove the hub/bearing from the caliper adapter.

20. Remove the adapter from the rear axle.

Fig. 142 Adapter Mounted In Vise:

21. Mount the adapter in a vise using the anchor boss for the park brake cable (Fig. 142).

Fig. 143 Lower Return Spring:

Fig. 145 Brake Shoe Adjuster:

24. Remove the adjuster (Fig. 145) from the leading and trailing park brake shoe.

Fig. 146 Primary Brake Shoe Remove/Install:

25. Remove the leading park brake shoe (Fig. 146) from the adapter. Leading brake shoe is removed by rotating the bottom of the brake shoe inward (Fig. 146) until the top of the brake shoe can be removed from the brake shoe anchor. Then remove the upper return springs (Fig. 146) from the leading brake shoe.

Fig. 147 Upper Return Springs:

26. Remove the upper return springs (Fig. 147) from the trailing park brake shoe.

Fig. 148 Trailing Brake Shoe Hold Down Pin And Spring:

28. Remove the trailing park brake shoe from the adapter.
29. Remove the park brake shoe actuator from the adapter and inspect for signs of abnormal wear and binding at the pivot point.

INSTALLATION
1. Install park brake shoe actuator into adapter.
2. Install the trailing brake shoe on the adapter.

NOTE: When the hold down pin is installed, the long part of the hold down pin is to be positioned strait up and down. This will ensure that the hold down pin is correctly engaged with the adapter.

3. Install the hold down spring and pin (Fig. 148) on the trailing park brake shoe.
4. Install the upper return springs (Fig. 147) on the trailing park brake shoe.
5. Install the upper return springs on the leading park brake shoe (Fig. 146). Then position the top of the leading park brake shoe at the upper anchor and rotate the bottom of the shoe outward until correctly installed on the adapter.
6. Install the adjuster (Fig. 145) between the leading and trailing park brake shoe.

NOTE: When the hold down pin is installed, the long part of the hold down pin is to be positioned strait up and down. This will ensure that the hold down pin is correctly engaged with the adapter.

7. Install the hold down spring and pin (Fig. 144) on the leading park brake shoe.
8. Install the lower return spring (Fig. 143) on the leading and trailing park brake shoes. When installing the return spring, it is to be installed behind the park brake shoes (Fig. 143).
9. Install the 4 mounting bolts for the adapter and hub/bearing into the bolt holes in the axle.

Fig. 149 Adapter Installed On Mounting Bolts (AWD Shown):

10. Position the adapter on the 4 mounting bolts installed in the rear axle (Fig. 149).
11. Install the hub/bearing on the stub shaft of outer C/V joint (AWD only) and into the end of the axle. (Fig. 140).
12. In a progressive crisscross pattern, tighten the 4 hub/bearing mounting bolts until the hub/bearing is squarely seated against the axle. Then tighten the hub/bearing mounting bolts to a torque of 129 Nm (95 ft. lbs.).
13. AWD only - Install the wheel speed sensor on the hub/bearing and adapter. Install the wheel speed sensor attaching bolt (Fig. 137). Tighten the wheel speed sensor attaching bolt to a torque of 12 Nm (105 inch lbs.).
14. FWD only - Install the wheel speed sensor in the following fashion:
a. If metal wheel speed sensor retaining clip is not in the neutral installed position on hub and bearing cap, install from the bottom, if necessary, and push clip upward until it snaps into position.
b. Install wheel speed sensor head into rear of hub and bearing aligning index tab with the notch in the top of the mounting hole. Push the sensor in until it snaps into place on the metal retaining clip.
c. Install secondary (yellow) retaining clip over wheel speed sensor head and engage the tabs on each side.
15. Install the park brake cable into its mounting hole in the adapter. Be sure all the locking tabs on the park brake cable retainer are expanded out to ensure the cable will not pull out of the adapter.
16. Install the end of the park brake cable on the park brake actuator lever (Fig. 135).
17. Attach park brake cable to adapter using mounting bolt.
18. Remove the locking pliers (Fig. 131) from the front park brake cable.
19. Adjust the park brake drum-in-hat brake shoes.
20. Install the rotor on the hub/bearing.
21. Carefully lower caliper and brake shoes over rotor and onto the adapter using the reverse procedure for removal (Fig. 133).

CAUTION: When installing guide pin bolts extreme caution should be taken not to crossthread the caliper guide pin bolts.

22. Install the caliper guide pin bolts (Fig. 132). Tighten the guide pin bolts to a torque of 35 Nm (26 ft. lbs.).
23. AWD only - Clean all foreign material off the threads of the outer C/V joint stub shaft. Install the washer and hub nut (Fig. 130) on the stub shaft of the outer C/V joint.
24. AWD only - Set the parking brake.
25. AWD only - Tighten the hub nut to a torque of 244 Nm (180 ft. lbs.).
26. AWD only - Install the spring washer (Fig. 129) on the stub shaft of the outer C/V joint.
27. AWD only - Install the nut retainer and cotter pin (Fig. 128) on the stub shaft of the outer C/V joint.
28. Install the wheel and tire assembly Tighten the wheel mounting stud nuts in proper sequence until all nuts are torqued to half specification. Then repeat the tightening sequence to the full specified torque of 135 Nm (100 ft. lbs.).
29. Lower vehicle.
30. Fully apply and release the park brake pedal one time. This will seat and correctly adjust the park brake cables.

CAUTION: Before moving vehicle, pump the brake pedal several times to insure the vehicle has a firm brake pedal to adequately stop vehicle.

31. Road test the vehicle and make several stops to wear off any foreign material on the brakes and to seat the brake shoe linings.
