1. Raise the rear of the vehicle, and support it with safety stands in the proper locations. Service and Repair
2. Remove the wheel nuts (A) and rear wheel.
3. Remove the brake caliper bracket mounting bolts (A), then remove the caliper assembly (B) from the knuckle. To prevent damage to the caliper assembly or the brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage. Do not twist the brake hose excessively.
4. Remove the flange bolt (A) and wheel speed sensor (B) from the knuckle. Do not disconnect the wheel speed sensor connector.
5. Raise the stake (A) of the spindle nut (B), and remove the nut.
6. Remove the rear brake disc. Rear Brake Disc Replacement
7. Check the rear hub for damage and cracks.
8. Remove the self-locking nut (A), adjusting cam plate (B), and adjusting bolt (C), then disconnect the control arm (D) from the frame.
NOTE: Use a new adjusting bolt and a new self-locking nut during reassembly.
9. Remove the lock pin (A) from the control arm ball joint, then remove the castle nut (B).
NOTE: During installation, install the lock pin as shown after tightening the castle nut.
10. Disconnect the control arm ball joint from the knuckle using the ball joint thread protector and the ball joint remover. Ball Joint Removal
NOTE: Turn the control arm (C) outward to install the ball joint remover.
11. Remove the control arm.
12. Remove the cotter pin (A) from the lower arm ball joint, then remove the castle nut (B).
NOTE: During installation, install the new cotter pin after tightening the castle nut, and bend its end as shown.
13. Disconnect the lower arm ball joint from the lower arm using the ball joint thread protector and the ball joint remover. Ball Joint Removal
NOTE:
- Be careful not to damage the ball joint boot when installing the remover.
- Do not force or hammer on the lower arm, or pry between the lower arm and the knuckle. You could damage the ball joint.
14. Remove the lock pin (A) from the upper arm ball joint, then remove the castle nut (B).
NOTE: During installation, install the lock pin as shown after tightening the castle nut.
15. Disconnect the upper arm ball joint from the knuckle using the ball joint thread protector and the ball joint remover. Ball Joint Removal
16. Remove the driveshaft outboard joint (A) from the knuckle (B) by tapping the driveshaft end (C) with a soft face hammer while drawing the hub outward, then remove the knuckle.
NOTE: Do not pull the driveshaft outward. The driveshaft inboard joint may come apart.
17. Separate the hub (A) from the knuckle (B) using the hub dis/assembly tool and a hydraulic press. Hold the knuckle with the attachment (C) of the hydraulic press or equivalent tool. Be careful not to damage or deform the splash guard (D). Hold onto the hub to keep it from falling when pressed clear.
18. Remove the screws (A), the splash guard (B), and the snap ring (C) from the knuckle (D).
19. Press the wheel bearing (A) out of the knuckle (B) using the driver handle, the attachment, and a press.
20. Press the wheel bearing inner race (A) out of the hub (B) using the hub dis/assembly tool, a commercially available bearing separator (C), and a press.
21. Wash the knuckle and the hub thoroughly in a high flash point solvent before reassembly.
22. Press a new wheel bearing (A) into the knuckle (B) using the old bearing (C), a steel plate (D), the support base, and a press. Place the wheel bearing on the knuckle with the pack seal side facing (E) (metal color) toward the inside. Be careful not to damage the sleeve of the pack seal.
23. Install the snap ring (A) securely in the knuckle (B).
24. Install the splash guard (C), and tighten the screws (D) to the specified torque value.
25. Install the hub (A) onto the knuckle (B) using the driver handle, the attachment, the support base, and a hydraulic press. Be careful not to damage the splash guard (C).
26. Install the knuckle in the reverse order of removal, and note these items:
- First install all of the components, and lightly tighten the bolts and the nuts, then raise the suspension to load it with the vehicle's weight before fully tightening to the specified torque values.
- Be careful not to damage the ball joint boot when connecting the knuckle.
- Use the new spindle nut during reassembly.
- Before installing the spindle nut, apply a small amount of engine oil to the seating surface of the nut. After tightening, use a drift to stake the spindle nut shoulder against the driveshaft.
- Before connecting the ball joint to the knuckle, degrease the threaded section and tapered portion of the ball joint pin, the ball joint connecting hole, the threaded section, and the mating surfaces of the castle nut.
- Torque the castle nut to the lower torque specification, then tighten it only far enough to align the slot with the ball joint pin hole. Do not align the castle nut by loosening it.
- Before installing the brake disc, clean the mating surfaces of the rear hub and the inside of the brake disc.
- Before installing the wheel, clean the mating surfaces of the brake disc and the inside of the wheel.
27. Check the wheel alignment, and adjust it if necessary. Service and Repair
