Special Tools Required 

• Hub dis/assembly tool 07GAF-SE00100
• Ball joint remover, 28 mm 07MAC-SL00200
• Attachment 62 x 68 mm 07746-0010500
• Driver 07749-0010000
• Support base 07965-SD90100

1. Raise the front of the vehicle, and make sure it is securely supported.
2. Remove the wheel cap, wheel nuts, and front wheel.

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

7. Screw two 8 x 1.25 mm bolts (B) into the disc to push it away from the hub. Turn each bolt 2 turns at a time to prevent cocking the disc excessively.
8. Remove the flange bolt (A) and wheel sensor (B) from the knuckle. Do not disconnect the wheel sensor connector.

10. Remove the clip (A) from the lower arm ball joint, and remove the castle nut (B).
    NOTE: During installation, insert the clip into the ball joint pin in the range of 180 degrees or below from the inside of the vehicle. Insert the clip from the inside to the outside of the vehicle.

11. Disconnect the lower arm from the knuckle using the special tool (see BALL JOINT REMOVAL ).
12. Loosen the damper pinch bolts (A) while holding the nuts (B), and remove the bolts and nuts.

13. Remove the driveshaft outboard joint (A) from the knuckle (B) by tapping the driveshaft end (C) with a plastic hammer while drawing the knuckle outward, then remove the knuckle.
    NOTE: Do not pull the driveshaft end outward. The driveshaft joint may come off.
14. Separate the hub (A) from the knuckle (B) using the special tool and a hydraulic press. Take care not to deform the splash guard. Hold onto the hub to keep it from falling when pressed clear.

18. Wash the knuckle and hub thoroughly in high flash point solvent before reassembly.
19. 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.

21. Install the splash guard (C), and tighten the screws (D) to the specified torque.
22. Press a new hub bearing unit (A) into the hub (B) using the special tools and a press.

23. Install the knuckle/hub/hub bearing unit in the reverse order of removal, and note these items:
    • Be careful not to damage the ball joint boot when installing the knuckle.
    • 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 clip 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 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, clean the mating surface of the front 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.
    • Check the front wheel alignment, and adjust it if necessary (see WHEEL ALIGNMENT ).
