Knuckle/Hub

Removal
1. Loosen the wheel nuts slightly.
2. Raise the front of car and support on safety stands in proper locations.
3. Remove the wheel nuts and wheel.





4. Raise the locking tab on the spindle nut, then remove the nut.





5. Remove the mounting bolts for the brake hose bracket.
6. Remove the caliper mounting bolts and hang the caliper assembly to one side

CAUTION: To prevent accidental damage to the caliper assembly or brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage.





7. Remove the 6 mm brake disc retaining screws.
8. Screw two 8 x 1.25 mm bolts into the disc to push it away from the hub.

NOTE: Turn each bolt two turns at a time to prevent cocking the disc excessively.

9. Remove the brake disc from the knuckle.





10. Remove the speed sensor wire bracket, then remove the speed sensor from the knuckle.

NOTE:
- Do not disconnect the speed sensor wire.
- Use ball joint removers, to separate the ball joints from the suspension or steering arm.

CAUTION: Be careful not to damage the ball joint boot.





11. Clean any dirt or grease off the ball joint.
12. Apply grease to the special tool on the areas shown. This will ease installation of the tool and prevent damage to the pressure bolt threads.





13. Remove the cotter pin from the steering arm and remove the nut.
14. Install a 12 mm hex nut on the ball joint. Be sure that the hex nut is flush with the ball joint pin end to prevent damage to the threaded end of the ball joint.
15. Use the ball joint remover as shown.
Insert the jaws carefully, making sure you do not damage the ball joint boot. Adjust the jaw spacing by turning the pressure bolt.

NOTE: If necessary, apply penetrating type lubricant to loosen the ball joint.





16. Once the tool is in place, turn the adjusting bolt as necessary to make the jaws parallel. Then hand- tighten the pressure bolt and recheck the jaws to make sure they are still parallel.
17. With a wrench, tighten the pressure bolt until the ball joint shaft pops loose from the steering arm.

Warning: Wear eye protection. The ball joint can break loose suddenly and scatter dirt or other debris in your eyes.

18. Remove the tool, then remove the nut from the end of the ball joint and pull the ball joint out of the steering/suspension arm.
Inspect the ball joint boot and replace it if damaged.





19. Remove the cotter pin and lower arm ball joint nut.
20. Install a 14 mm hex nut on the ball joint. Be sure that the hex nut is flush with the ball joint pin end, or the threaded section of the ball joint pin might be damaged by the ball joint remover.
21. Use the bail joint remover to separate the ball joint and lower arm.

NOTE: If necessary, apply penetrating type lubricant to loosen the ball joint.

22. Remove the knuckle protector.
23. Remove the cotter pin and the upper ball joint nut.
24. Install a 10 mm hex nut on the ball joint. Be sure that the hex nut is flush with the ball joint pin end, or the threaded section of the ball joint pin might be damaged by the ball joint remover.





25. Use the ball joint remover to separate the ball joint and knuckle.

NOTE: If necessary, apply penetrating type lubricant to loosen the ball joint.





26. Pull the knuckle outward and remove the driveshaft outboard joint from the knuckle using a plastic hammer, then remove the knuckle.



Hub Unit and Wheel Bearing Replacement

NOTE: Replace the bearing with a new one after removal.





27. Separate the hub from the knuckle using the special tools and a hydraulic press.

CAUTION:
^ Take care not to distort the splash guard.
^ Hold onto the hub to keep it from falling when pressed clear.





28. Remove the knuckle ring from the knuckle.





29. Remove the circlip and the splash guard from the knuckle.





30. Press the wheel bearing out of the knuckle using a hydraulic press and the special tools shown below.





31. Remove the outboard bearing inner race from the hub using the special tools shown and a commercially available bearing separator.

NOTE: Wash the knuckle and hub thoroughly in high flash-point solvent before reassembly.





32. Press a new wheel bearing into the hub using the special tools shown and a hydraulic press.





33. Install the circlip securely in the knuckle groove.
34. Install the splash guard and tighten the screws.





35. Install the hub on the knuckle using the special tools shown and a hydraulic press.

CAUTION: Take care not to distort the splash guard.





36. Install the knuckle ring on the knuckle.


Installation

CAUTION:
^ Be careful not to damage the ball joint boot.
^ Torque the castle nut to the lower torque specification then tighten it only far enough to align the slot with the pin hole. Do not align the nut by loosening.

37. Install the knuckle on the driveshaft.





38. Install the knuckle on the lower arm and the tie-rod, then tighten the castle nuts and install new cotter pins.
39. Install the knuckle on the upper arm, then tighten the castle nut and install a new cotter pin.





40. Install the knuckle protector with the 6 mm bolt.





41. Install the speed sensor with the sensor mounting bolts.

NOTE: Be careful when installing the sensors to avoid twisting wires.

42. Install the sensor wire with the two bolts.





43. Install the brake disc with the 6 mm brake disc retaining screws.





44. Install the brake caliper with the caliper mounting bolts.
45. Install the brake hose with the brake hose mounting
46. Tighten the new spindle nut,

NOTE: Before installing the wheel, clean the mating surface of the brake disc and inside of the wheel.





47. Install the wheel with the wheel nuts.
48. Check the front wheel alignment and adjust if necessary.
