Rear Suspension
HUB AND BEARING1. 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.
HUB AND BEARING - SRT8
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).
CAUTION: When pushing pistons back into caliper bores, use only a trim stick as shown or other suitable soft tool. Never use a screwdriver or other metal pry bar due to potential damage to braking surface of rotor, caliper, pistons or dust boots.
4. Place trim stick (4) between brake pad (2) and outer edge of rotor (3).
5. Using trim stick, slowly apply pressure against brake pad (2) until both pistons (on that side of caliper) are completely bottomed in bores of caliper half.
NOTE: Repeat above procedure to opposite brake pad (1) and pistons as necessary.
6. Support spring link (1) using a transmission jack (5) or other appropriate jack. Raise spring link just enough to access brake caliper lower mounting bolt (4) from above compression link (2).
7. Remove the lower and upper caliper mounting bolts (1).
8. Remove brake caliper (2) with pads from knuckle and brake rotor. Hang assembly out of way using wire or a bungee cord. Use care not to overextend brake hose when doing this.
9. Remove any clips (3) retaining brake rotor (2) to wheel mounting studs.
10. Slide brake rotor (2) off hub and bearing (1).
11. Push inward on end of half shaft (2) until C/V joints bottom. This is necessary to give as much access to hub and bearing mounting bolts as possible.
NOTE: It is important to keep suspension jacked up as requested in Step 6 to ease access to lower hub and bearing mounting bolts.
NOTE: Use a 3/8 inch drive wobble extension along with a Torx� socket to access and remove two top and lower front mounting bolt. Use a standard 3/8 inch drive universal joint along with a Torx� socket to access and remove lower rear mounting bolt.
12. Loosen each (of the four) hub and bearing mounting bolt 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 parking brake adapter to keep brake adapter in place while hub and bearing is off vehicle.
13. Slide hub and bearing out of knuckle and off half shaft.
INSTALLATION
HUB AND BEARING
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.
HUB AND BEARING - SRT8
NOTE: Before installing hub and bearing on end of axle half shaft, ensure isolation washer (1) 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.
NOTE: To help upon installation, make sure that hub and bearing mounting bolts (1) extend through knuckle (3) and parking brake adapter (2) to hold adapter in place during hub and bearing installation.
1. Position hub and bearing mounting bolts (1) though rear of knuckle (3) and parking brake adapter (2) just enough to hold adapter in place.
NOTE: Hub and bearing mounting bolt holes are not evenly spaced. Upper mounting holes (2) are not as far apart as lower mounting holes (1). Make note of this before installing hub and bearing.
2. Slide hub and bearing onto half shaft. Insert hub and bearing through parking brake adapter and knuckle, lining up mounting bolt holes with bolts.
NOTE: Make sure suspension is jacked up as requested during removal to ease access to lower hub and bearing mounting bolts.
NOTE: Use a 3/8 inch drive wobble extension along with a Torx� socket to slip past half shaft outer C/V joint and install two top and lower front mounting bolts. Use a standard 3/8 inch drive universal joint along with a Torx� socket to install lower rear mounting bolt.
3. Carefully start all four mounting bolts into hub and bearing. Using a cross pattern, tighten each hub and bearing mounting bolt a turn or two at a time, slowly drawing hub and bearing into mounted position. Periodically, push in on end of half shaft to give as much room as possible for tools on mounting bolts. Tighten mounting bolts to 68 Nm (50 ft. lbs.) torque.
NOTE: Inspect disc brake pads and parking brake shoes before brake rotor installation.
4. Clean hub face (1) to remove any dirt or corrosion where rotor mounts.
5. Install brake rotor (2) over studs on hub and bearing (1).
6. Slide caliper with pads (2) over brake rotor and align with knuckle.
7. Install caliper mounting bolts (1). Tighten bolts to 130 Nm (96 ft. lbs.) torque.
8. Remove jack from under spring link.
9. 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.
10. Verify proper adjustment of the parking brake shoes and adjust as necessary.
11. Install tire and wheel assembly (1). Tighten wheel mounting nuts (3) to 150 Nm (110 ft. lbs.) torque.
12. Lower vehicle.
13. Pump brake pedal several times to ensure vehicle has a firm brake pedal before moving vehicle.
14. Check and adjust brake fluid level in reservoir (1) as necessary.
15. Road test vehicle and make several stops to wear off any foreign material on brakes and to seat brake pads.
