NOTICE: To avoid damage, do not strike aluminum parts with a metal hammer. If necessary, tap gently with a plastic tipped hammer.

NOTE: Nuts and bolts with the [star] mark are special corrosion-resistant Dacro fasteners. Use the same type if replacement is necessary.

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





2. Remove the center cap (A), wheel nuts (B), and front wheel (C).





3. Remove the brake hose bracket mounting bolt (A).
4. Remove the caliper bracket mounting bolts (B), and remove the caliper assembly (C) from the knuckle. To prevent damage to the caliper assembly or brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage. Do not twist the brake hose with force.





5. Remove the spindle nut (A).





6. Remove the brake disc retaining flat screws (A).
7. 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.





8. Remove the flange bolts (A) and wheel sensor (B) from the knuckle. Do not disconnect the wheel sensor connector.





9. Turn the front of the knuckle outward. Tap the driveshaft (A) inward with a plastic hammer to allow space to install the special tool on the lower arm ball joint.





10. Remove the cotter pin (A) from the lower arm ball joint, and remove the castle nut (B).
11. Remove the lower arm ball joint from the knuckle using the special tool.

NOTE: Make sure you position the ball joint remover jaw on the bushing (D) and not on the aluminum surface of the knuckle.





12. Loosen the damper pinch bolts (A) while holding the nuts (B), and remove the bolts and nuts.
13. Pull the knuckle off of the driveshaft while holding the outboard joint (c), and remove the knuckle from the damper.

NOTE: Do not pull the driveshaft end outward. The driveshaft joint may come off.





14. Separate the hub (A) from the hub bearing unit (B) using the special tool and a press. Hold onto the hub to keep it from falling when pressed clear.





15. Press the wheel bearing inner race (A) out of the hub (B) using the special tool, a commercially available bearing separator (C), and a press.





16. Remove the splash guard (A) from the knuckle (B).





17. Remove the flange bolts (A), and remove the hub bearing unit (B) from the knuckle.
18. Wash the knuckle and hub thoroughly in high flash point solvent before reassembly.





19. Install the hub bearing unit (A) on the knuckle (B), and tighten the flange bolts (C) to the specified torque.





20. Install the splash guard.

NOTE: Replace the splash guard if it is corroded.





21. Press a new hub bearing unit (A) into the hub (B) using the special tools and a press.
22. Install the knuckle/hub/hub bearing unit in the reverse order of removal, and note these items:
- 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.
- Tighten all mounting hardware to the specified torque values.
- Before installing the hub/hub bearing unit, clean the mating surface of the hub/hub bearing unit and the knuckle.
- Before installing the brake disc, clean the mating surface of the hub and the inside of the brake disc.
- Before installing the wheel, clean the mating surface of the brake disc and the inside of the wheel.
- Set the wheel alignment.
