1. Loosen the wheel nuts slightly.
2. Raise the front of the vehicle and make sure it is securely supported.
3. Remove the wheel nuts (A) and front wheel (B).
4. Raise the locking tab on the spindle nut (c), then remove the nut.
5. Remove the brake hose mounting bolts (A).
6. 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.
7. Remove the wheel sensor (A) from the knuckle (B) (for vehicles with ABS). Do not disconnect the wheel sensor connector.
8. Remove the 6 mm brake disc retaining screws (A).
9. Screw two 8 x 1.25 mm bolts (B) into the disc to push it away from the hub. Turn each bolt two turns at a time to prevent cocking the disc excessively.
10. Remove the brake disc from the knuckle.
11. Check the front hub for damage and cracks.
12. Remove the cotter pin (A) from the tie-rod end ball joint. Then loosen the nut (B).
13. Remove the tie-rod ball joint from the knuckle using the special tool.
14. Remove the cotter pin (A) from the lower arm ball joint castle nut (B), and remove the nut.
15. Remove the lower ball joint from the knuckle using the special tool.
16. Remove the cotter pin (A) from the upper ball joint castle nut (B), and remove the nut.
17. Remove the upper ball joint from the knuckle using the special tool.
18. Pull the knuckle outward, and remove the driveshaft outboard joint (B) from the knuckle (A) by tapping the driveshaft end (C) with a plastic hammer, then remove the knuckle.
19. Separate the hub (A) from the knuckle (B) using the special tool and a hydraulic press. Take care not to distort the splash guard. Hold onto the hub to keep it from falling when pressed clear.
20. Remove the circlip (A) and the splash guard (B) from the knuckle (C).
21. Press the wheel bearing (A) out of the knuckle (B) using the special tools and a press.
22. Press the wheel bearing inner race (A) from the hub (B) using the special tool, a commercially available bearing separator (C), and a press.
23. Wash the knuckle and hub thoroughly in high flash point solvent before reassembly.
24. Press a new wheel bearing (A) into the knuckle (B) using the old bearing (C), a steel plate (D), the special tool, and a press. Place the wheel bearing on the knuckle with the pack seal side facing (metal color) toward the inside. Be careful not to damage the sleeve of the pack seal.
25. Install the circlip (A) securely in the knuckle (B).
26. Install the splash guard (c), and tighten the screws (D).
27. Install the hub (A) on the knuckle (B) using the special tools shown and a hydraulic press. Be careful not to distort the splash guard (C).
28. Install the knuckle in the reverse order of removal, and pay particular attention to the following items.
- Be careful not to damage the ball joint boots when installing the knuckle.
- Torque all mounting hardware to the specified torque values.
- Torque the castle nuts to the lower torque specifications, then tighten them only far enough to align the slot with the pin hole. Do not align the castle nut by loosening.
- Install new cotter pins on the castle nuts after torquing.
- Raise the locking tab on the spindle nut (c), then remove the nut.
- Before installing the brake disc, clean the mating surface of the front hub and the inside of the brake disc.
- Before installing the spindle nut, apply a small amount of motor 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 wheel, clean the mating surface of the brake disc and the inside of the wheel.
- Check the front wheel alignment, and adjust it if necessary.
