Rear Suspension
REARHUB AND BEARING
REMOVAL
1. Raise and support vehicle.
2. Remove wheel mounting nuts (3), then tire and wheel assembly (1).
3. While a helper applies brakes to keep hub from rotating, remove hub nut (1) from the half shaft (2).
NOTE: In some cases, it may be necessary to retract caliper piston in its bore a small amount in order to provide sufficient clearance between shoes and rotor to easily remove caliper from knuckle. This can usually be accomplished before guide pin bolts are removed, by grasping rear of caliper and pulling outward working with guide pins, thus retracting piston. Never push on piston directly as it may get damaged.
4. Remove two bolts (1) securing disc brake caliper adapter (3) to knuckle (2).
5. Remove disc brake caliper and adapter (3) from knuckle as an assembly. Hang assembly out of way using wire or a bungee cord. Use care not to overextend brake hose when doing this.
6. Remove any clips (2) retaining brake rotor (3) to wheel mounting studs.
7. Slide brake rotor (3) off hub and bearing (1).
8. Loosen each hub and bearing mounting bolt (2) a turn or two at a time while pulling outward on hub and bearing to avoid bolt contact with half shaft outer joint. Once removed from threads in hub and bearing (but not knuckle), allow bolts to stay in and protrude through knuckle and brake support plate to keep brake support plate in place when hub and bearing is removed.
9. Slide hub and bearing off knuckle and half shaft.
INSTALLATION
NOTE: Before installing hub and bearing on end of axle half shaft, ensure isolation washer is present on end of half shaft. Inspect washer making sure it is not worn or damaged. Washer can be installed in either direction on shaft.
1. 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.
2. Slide hub and bearing onto half shaft. Place hub and bearing through brake support, onto knuckle, lining up mounting bolt holes with bolts.
3. Install four bolts (2) fastening hub and bearing in place. Tighten mounting bolts to 68 Nm (50 ft. lbs.) torque.
NOTE: Inspect disc brake pads and parking brake shoes before brake rotor installation.
4. Install brake rotor (3) over wheel mounting studs and onto hub (1).
5. Install disc brake caliper and adapter assembly (3) over brake rotor.
6. Install mounting bolts (1) securing caliper adapter (3) to knuckle (2). Tighten bolts to 95 Nm (70 ft. lbs.) torque.
7. Install hub nut (1) on end of half shaft (2). While a helper applies brakes to keep hub from turning, tighten hub nut to 213 Nm (157 ft. lbs.) torque.
8. Verify proper adjustment of the parking brake shoes and adjust as necessary.
9. Install tire and wheel assembly (1). Tighten wheel mounting nuts (3) to 150 Nm (110 ft. lbs.) torque.
10. Lower vehicle.
11. Pump brake pedal several times to ensure vehicle has a firm brake pedal before moving vehicle.
12. Check and adjust brake fluid level in reservoir (1) as necessary.
13. Road test vehicle and make several stops to wear off any foreign material on brakes and to seat brake pads.
