Adjustment
- Place parking brake lever in -full released- position.
- Raise and support vehicle.
- Remove plug in parking brake shoe support to access adjuster star-wheel.
- Through the access hole, rotate the adjuster star wheel in the following direction to expand the shoes outward against the drum:
- Left brake - Rotate star-wheel toward rear of vehicle.
- Right brake - Rotate star-wheel toward front of vehicle.
- Using an appropriate tool, turn adjuster star wheel until wheel will not rotate (dead lock).
- Back off adjuster six detents (teeth).
- Rotate wheel, checking for light drag. If drag is too heavy, continue to back off adjuster one detent at a time until light drag is present. Do not back off star-wheel more than 17 detents from wheel lock.
- Install access plug.
- Adjust opposite wheel parking brake shoes using same method.
- Lower vehicle.
- Apply and release parking brake lever once to ensure proper operation of parking brakes.

To install:
- Install return spring between upper and lower shoes.
NOTE
Before installing shoes on actuator, make sure actuator hooked to rear cable is positioned with word -UP- facing outward.
- Install upper and lower shoes with return spring on shoe actuator located on parking brake cable.
- Install lower brake shoe hold-down pin through rear of support and lower shoe, then install hold-down clip.
- Install upper brake shoe hold-down pin through rear of support and upper shoe, then install hold-down clip.
- Install shoe adjuster. Place end of adjuster with star wheel upward.
- Install parking brake shoe adjuster spring.
- Install bolt securing parking brake cable to knuckle and tighten bolt to 21 ft. lbs. (28 Nm).
- Using Brake Shoe Gauge, Special Tool C-3919, or equivalent, measure inside diameter of parking brake drum portion of rotor.
- Place Gauge over parking brake shoes at widest point.
- Using adjuster star wheel, adjust parking brake shoes until linings on both park brake shoes just touch jaws on gauge. This will give a good preliminary adjustment of parking brake shoes, before a final adjustment is made at end of this procedure.
- Install hub and bearing with wheel speed sensor as well as all components necessary to access it.

This vehicle is equipped with permanently sealed rear wheel bearings. There is no periodic lubrication or maintenance recommended for these units.
Removal & Installation
- Raise and support vehicle.
- Remove wheel mounting nuts, then tire and wheel assembly.
- If equipped with AWD:
- Remove cotter pin, nut lock and spring washer from half shaft.
- While a helper applies brakes to keep hub from turning, remove hub nut and washer.
- Remove brake caliper and rotor from hub and bearing assembly.
Fig. Hub assembly
- Disconnect vehicle wiring harness connector at wheel speed sensor connector.
- Unclip wheel speed sensor connector from spare tire mounting support.
- Disconnect two sensor cable routing clips on rear suspension crossmember.
- Disconnect two sensor cable routing clips along toe link.
- Disconnect sensor cable from bracket on brake support.
- Completely loosen, but do not remove four bolts fastening hub and bearing in place. Once loosened from threads in hub and bearing, push bolts up against rear of hub and bearing to keep brake support plate in place when hub and bearing is removed.

To install:
- Position hub and bearing bolts though rear of knuckle and parking brake support just enough to hold support in place as hub and bearing is installed.
- Install hub and bearing by first feeding end of wheel speed sensor cable through hole in bottom of parking brake support. As this is being done, if equipped with AWD, slide hub and bearing onto half shaft. Place hub and bearing through brake support, onto knuckle, lining up mounting bolt holes with bolts and placing wheel speed sensor head at bottom.
- Install four bolts fastening hub and bearing in place. Tighten mounting bolts to 60 ft. lbs. (81 Nm).
- Place wheel speed sensor cable routing grommet into bracket on parking brake support.
- Route wheel speed sensor cable along toe link and rear suspension crossmember connecting routing clips where shown.
- Connect vehicle wiring harness to wheel speed sensor connector.
- Install brake rotor and caliper.
- If equipped with AWD:
- Install washer and hub nut on end of half shaft.
- While a helper applies brakes to keep hub from turning, tighten hub nut to 180 ft. lbs. (244 Nm).
- Install spring washer, nut lock and cotter pin on end of half shaft.
- Install tire and wheel assembly. Install and tighten wheel mounting nuts to 100 ft. lbs. (135 Nm).
