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






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





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

8. Check the front hub for damage and cracks.

9. Remove the cotter pin (A) from the tie-rod end ball joint, then remove the nut (B).

NOTE: During installation, install the new cotter pin after tightening the nut, and bend its ends as shown.





10. Disconnect the tie-rod end ball joint from the knuckle using the ball joint thread protector and the ball joint remover Ball Joint Removal.

11. Remove the lock pin (A) from the lower ball joint (B), then remove the castle nut (C).

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





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

13. Remove the damper pinch bolts (A) and the flange nuts (B) from the damper.

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





14. Remove the driveshaft outboard joint (C) from the knuckle (D) by tapping the driveshaft end (E) with a soft face hammer while drawing the hub outward, then remove the knuckle.

NOTE:

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

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

- First install all the components, and lightly tighten the bolts and the nuts, then raise the suspension by loading it with the vehicle's weight before fully tightening to the specified torque.
- Be careful not to damage the ball joint boot when installing the knuckle.
- Before connecting the lower ball joint to the knuckle, degrease the threaded section and tapered portion of the ball joint pin, the knuckle connecting hole, the threaded section, and 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 during 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.

16. 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 press. Hold the knuckle with the attachment (C) of the 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 the wheel bearing inner race (A) off 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 attachment, the driver handle, and a press.





6. Wash the knuckle and hub thoroughly in 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 attachment, the support base, and a press.

NOTE:

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





8. Install a 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. Install the hub (A) onto the knuckle (B) using the attachment, the driver handle, the support base, and a press. Be careful not to damage the splash guard (C).





11. Install the knuckle/hub.
