1. Raise the rear of the vehicle, and support it with safety stands in the proper locations.
2. Remove the wheel nuts and rear wheels.
3. Remove the brake hose bracket mounting bolts (A) from the trailing arm.
4. Remove the brake hose bracket mounting bolts (A) from the knuckle.
5. Remove the caliper mounting bolts (B), and hang the caliper assembly (C) to one side. To prevent damage to the caliper assembly or brake hose, use a short piece of wire to hang the caliper from the undercarriage.
6. Remove the wheel sensor (A) and sensor harness from the knuckle (B). Do not disconnect the wheel sensor connector.
7. Raise the stake (A) of the spindle nut (B), then remove and discard the nut.
8. For 2WD models: Remove the rear axle shaft from the knuckle.
9. Remove the brake disc/drum retaining flat screws (A).
10. Remove the brake disc/drum (B) from the hub, and separate the rear hub. Check the rear hub for damage and cracks.
NOTE: If the brake disc/drum has clung to the hub, screw two 8 x 1.25 mm bolts (C) into the brake disc/drum to push it away from the hub. Turn each bolt two turns at a time to prevent cocking the disc excessively.
11. Remove the parking brake shoes, and parking brake cable.
12. Remove the lock pin (A) from the upper arm ball joint, then loosen the nut (B).
NOTE: During installation, install the new lock pin after tightening the nut.
13. Disconnect the upper arm ball joint from the knuckle using the ball joint remover.
14. Remove the flange nut (B), washer, and flange bolt (C), then remove the lower arm A.
NOTE: During installation, install a new flange nut.
15. Remove the flange bolts (A), and separate the knuckle from the trailing arm (B).
NOTE: During installation, install the new flange bolts.
16. Place a floor jack under lower arm B. Remove the self-locking nut (A), washer, and flange bolt (C).
NOTE: During installation, install new flange bolt, and new self-locking nut.
17. For 4WD models: Remove the knuckle while pushing in the driveshaft and holding the driveshaft outboard joint.
NOTE: Do not pull the driveshaft end outward. The inner driveshaft joint may come apart.
18. Separate the hub (A) from the knuckle (B) using the hub disassembly tool and a hydraulic press. Hold the knuckle with the attachment (C) of the hydraulic press or equivalent tool. Be careful not to deform the splash guard. Hold onto the hub to keep it from falling when pressed clear.
19. Remove the flange nuts (A), backing plate (B), and snap ring (C).
20. Press the wheel bearing (A) out of the knuckle (B) using the attachment, the driver and a press.
21. Press the wheel bearing inner race (A) from the hub (B) using the hub disassembly tool, commercially available bearing separator (C), and a press.
22. Wash the knuckle and hub thoroughly in high flash point solvent before reassembly.
23. 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. Be careful not to damage the sleeve of the pack seal.
24. Install the snap ring (A), backing plate (B), and flange nuts (C). Tighten the flange nuts to the specified torque.
25. Install the hub (A) on the knuckle (B) using the attachment, the driver, the support base, and a hydraulic press. Be careful not to deform the splash guard (C).
26. Install the knuckle in the reverse order of removal, and note these items:
^ Be careful not to damage the ball joint boot when installing the knuckle.
^ First install all the components and lightly tighten the bolts and nuts, then raise the suspension to load it with the vehicle's weight before fully tightening to the specified torque values.
^ Tighten all mounting hardware to the specified torque values.
^ Torque the castle nut to the lower torque specification, then tighten it only far enough to align the slot with the pin hole. Do not align the castle nut by loosening it.
^ Install a new clip on the castle nut after torquing.
^ Use a new spindle nut on reassembly.
^ Before installing the new 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 installing the brake disc/drum, clean the mating surfaces of the rear hub and the inside of the brake disc/drum. Before installing the wheel, clean the mating surfaces of the brake disc/drum and the inside of the wheel.
^ Check the rear wheel alignment, and adjust it if necessary.
