1. Raise the front of the vehicle, and support it with safety stands in the proper locations.





2. Remove the wheel nuts (A) and front wheel (B).





3. Remove the brake hose mounting bolt (A).
4. 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.





5. Remove the wheel sensor (A) from the knuckle (B). Do not disconnect the wheel sensor connector.





6. Raise the stake (A), and then remove the spindle nut (B).





7. Remove the 6 mm brake disc retaining screws (A).
8. Screw two 8 x 1.25 mm bolts (B) into the brake disc to push it away from the hub. Turn each bolt two turns at a time to prevent cocking the disc excessively.
9. Remove the brake disc from the knuckle.
10. Check the front hub for damage and cracks.





11. Remove the cotter pin (A) from the tie-rod end ball joint, then loosen the nut (B).
12. Remove the tie-rod ball joint from the knuckle using the special tool.





13. Remove the lock pin (A) from the lower arm ball joint castle nut (B), and remove the nut.
14. Remove the lower ball joint from the knuckle using the special tool.





15. Remove the damper pinch bolts (A) and flange nuts (B) from the damper.
16. Pull the knuckle outward, and remove the driveshaft outboard joint (C) from the knuckle (D) by tapping the driveshaft end (E) with a plastic hammer, then remove the knuckle.





17. Separate the hub (A) from the knuckle (B) using the special tool and a hydraulic press. Be careful not to distort the splash guard. Hold onto the hub to keep it from falling when pressed clear.





18. Remove the snap ring (A) and the splash guard (B) from the knuckle (C).





19. Press the wheel bearing (A) out of the knuckle (B) using the special tools and a press.





20. Press the wheel bearing inner race (A) from the hub (B) using the special tool, a commercially available bearing separator (C), and a press.
21. Wash the knuckle and hub thoroughly in 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 special tool, and a press. Place the wheel bearing on the knuckle with the magnetic encoder side (black color) facing toward the inside. Be careful not to damage the magnetic encoder.





23. Install the snap ring (A) securely in the knuckle (B).
24. Install the splash guard (C), and tighten the screws (D).





25. Install the hub (A) onto the knuckle (B) using the special tools shown and a hydraulic press. Be careful not to distort the splash guard (C).
26. 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.
^ 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 value. Do not place the jack against the ball joint pin of the knuckle.
^ Torque all mounting hardware to the specified torque values.
^ Before connecting the ball joint to the knuckle, degrease the threaded section and tapered portion of the ball joint pin, the connecting hole, and the threaded section and mating surface of the castle nut.
^ Torque the castle nuts to the lower torque specifications, then tighten them only far enough to align the slot with the ball joint pin hole. Do not align the castle nut by loosening it.
^ Install new lock pins on the castle nuts after torquing.
^ Before installing the brake disc, clean the mating surface of the front hub and the inside of the brake disc.
^ 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 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.
