Knuckle/Hub Replacement
1. Raise and support the vehicle Service and Repair.
2. Remove the wheel nuts (A) and the rear wheel.
3. Release the parking brake lever fully.
4. Remove the brake hose mounting bolt (A).
5. Remove the brake caliper bracket mounting bolts (B), then hang the caliper assembly (C) from the knuckle. To prevent damage to the caliper 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.
6. Remove the rear brake disc/drum from the rear hub Rear Brake Disc Replacement.
7. Pry up the stake (A) on the spindle nut (B), then remove the nut. Remove the rear axle shaft (C) from vehicles with 2WD.
8. Check the rear hub for damage and cracks.
9. Remove the parking brake shoes Removal and Replacement.
10. Remove the parking brake cable (A) from the backing plate.
NOTE: The parking brake cable must not be bent or distorted. This will lead to stiff operation and premature cable failure.
11. Remove the wheel speed sensor (A) from the knuckle. Do not disconnect the wheel speed sensor connector.
12. Place a floor jack under the trailing arm (A) to support it.
NOTE: Do not place the jack against the plate section of the trailing arm. Be careful not to damage any suspension components.
13. Remove the flange bolt (B), and disconnect the upper arm (C) from the knuckle.
NOTE: Use the new flange bolt during reassembly.
14. Mark the cam positions of the adjusting bolt (A) and adjusting cam (B) with the frame, then remove the self-locking nut (C), adjusting cam, and adjusting bolt.
NOTE: Use a new self-locking nut and a new adjusting bolt during reassembly.
15. Remove the flange bolt (D).
NOTE: Use the new flange bolt during reassembly.
16. 2WD: Remove the knuckle/hub from the trailing arm.
17. 4WD: Remove the knuckle (A) while pushing in the driveshaft and holding the driveshaft outboard joint (B).
NOTE: Do not pull the driveshaft end outward. The driveshaft inboard joint may come apart.
18. Install the knuckle/hub 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 place a floor jack under the trailing arm, and raise the suspension to load it with the vehicle's weight before fully tightening to the specified torque.
- Align the cam positions of the adjusting bolt and the adjusting cam with the marked positions when tightening the self-locking nut.
- Use a new spindle nut on 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 (4WD) or rear axle shaft (2WD).
- Before installing the brake disc/drum, clean the mating surfaces between the rear hub and the inside of the brake disc/drum.
- Before installing the wheel, clean the mating surfaces between the brake disc/drum and the inside of the wheel.
19. Check the wheel alignment, and adjust it if necessary Service and Repair.
Wheel Bearing Unit Replacement
1. Remove the brake hose mounting bracket (A).
2. Separate the wheel bearing unit (A) from the knuckle (B).
3. Separate the hub (A) and backing plate (B) from wheel bearing unit (C) using the hub dis/assembly pin and a hydraulic press. Hold the wheel bearing unit with a press attachment (D) or equivalent tool. Be careful not to damage or deform the backing plate. Hold onto the hub to keep it from falling when pressed clear.
4. Press out the wheel bearing inner race (A) of the hub (B) using the hub dis/assembly pin, a commercially available bearing separator (C), and a press.
5. Wash the knuckle and the hub thoroughly in a high flash point solvent before reassembly.
6. Install the hub (A) and backing plate (B) on the new wheel bearing unit (C) using the driver handle, the attachment, the support base and a hydraulic press. Be careful not to damage or deform the backing plate.
NOTE:
- Remove any oil, grease, dust, metal debris, and other foreign material from the magnetic encoder surface (D).
- Keep magnetic tools away from the magnetic encoder surface.
- Be careful not to damage the magnetic encoder surface.
7. Install the wheel bearing unit (A) to the knuckle (B).
NOTE: Use a new 16 mm flange nut (C) during reassembly.
8. Install the brake hose mounting bracket (A).
