NOTE: Refer to the Exploded View as needed during the following procedure.

Knuckle/Hub Replacement

1. Raise and support the vehicle Service and Repair.

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






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





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

5. Pry up the stake (A) on the spindle nut (B), then remove the nut.





6. Remove the front brake disc Front Brake Disc Replacement.

7. Check the front hub for damage and cracks.

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






9. Remove the flange nut (A) while holding the joint pin (B) with a hex wrench (C), and disconnect the stabilizer link (D) from the lower arm (E).

NOTE: Use the new flange nut during reassembly.






10. Remove the lock pin (A) from the knuckle ball joint, then remove the castle nut (B).

NOTE: During installation, install the lock pin as shown after tightening the new castle nut.





11. Disconnect the lower arm from the knuckle using the ball joint thread protector and the ball joint remover Ball Joint Removal.

NOTE:

- Be careful not to damage the ball joint boot when installing the remover.
- Do not force or hammer on the lower arm, or pry between the lower arm and the knuckle. You could damage the ball joint.

12. Remove the damper pinch bolts (A) while holding the flange nuts (B) from the damper.

NOTE: Use new damper pinch bolts and new flange nuts during reassembly.





13. Pull the knuckle (C) outward, and separate the outboard joint (D) from the front hub using a soft face hammer, then remove the knuckle/hub.

NOTE:

- Do not pull the driveshaft end outward. The driveshaft inboard joint may come apart.
- During installation, apply grease to the mating surfaces of the wheel bearing and the driveshaft outboard joint.

14. Install the knuckle/hub in the reverse order of removal, and note these items:

- First install all of the components, and lightly tighten the bolts and the nuts, then raise the suspension with a floor jack to load it with the vehicle's weight before fully tightening to the specified torque. Do not place the jack against the ball joint pin of the knuckle.
- Be careful not to damage the ball joint boot when installing the knuckle.
- Before connecting the knuckle ball joint to the lower arm, degrease the threaded section and the tapered portion of the ball joint pin, the ball joint connecting hole, the threaded section, and the mating surface of the castle nut.
- Torque the castle nut to the lower torque specification, then tighten it only far enough to align the slot with the ball joint pin hole. Do not align the castle nut by loosening it.
- 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 surfaces between the front hub and the inside of the brake disc.
- Before installing the wheel, clean the mating surfaces between the brake disc and the inside of the wheel.

15. Check the wheel alignment, and adjust it if necessary Service and Repair.

Wheel Bearing Replacement

1. Remove the knuckle/hub.

2. Separate the hub (A) from the knuckle (B) using the hub dis/assembly pin and a hydraulic press. Hold the knuckle with the attachment (C) of the hydraulic press or equivalent tool. Be careful not to damage or deform the splash guard (D). Hold onto the hub to keep it from falling when pressed clear.






3. Press out the wheel bearing inner race (A) of the hub (B) using the hub dis/assembly pin, a commercially available bearing separator (C), and a press.






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






5. Press the wheel bearing (A) out of the knuckle (B) using the driver handle, the attachment, and a press.





6. Wash the knuckle and the hub thoroughly in a high flash point solvent before reassembly.

7. 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 bearing seal (E).

NOTE:

- Install the wheel bearing with the magnetic encoder (F) (brown color) toward the inside of the knuckle.
- Remove any oil, grease, dust, metal debris, and other foreign material from the magnetic encoder surface.
- Keep magnetic tools away from the magnetic encoder surface.
- Be careful not to damage the magnetic encoder surface when you insert the wheel bearing.





8. Install the new snap ring (A) securely in the knuckle (B).





9. Install the splash guard (C), and tighten the screws (D) to the specified torque.

10. Press a wheel bearing (A) onto the hub (B) using the driver handle, the attachment, the support base, and a press. Be careful not to damage the splash guard (C).






11. Install the knuckle/hub.
