Front
REPLACEMENT1. Loosen the wheel nuts slightly.
2. Raise the front of the vehicle, and support it with safety stands in the proper locations.
3. Remove the wheel nuts and front 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:
CAUTION: Be careful not to damage the ball joint boot.
8. Screw two 8 x 12 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 wheel sensor from the knuckle.
NOTE: Do not disconnect the wheel sensor connector.
10. Clean any dirt or grease off the ball joint.
11. Remove the cotter pin from the ball joint castle nut, and remove the nut.
12. Install a 12 mm hex nut on the ball joint. Be sure that the 12 mm hex nut is flush with the ball joint pin end to prevent damage to the threaded end of the ball joint.
13. 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.
14. Install the special tool 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.
15. 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.
NOTE: After making the adjustment to the adjusting bolt, be sure the head of the adjusting bolt is in this position to the allow the jaw to pivot.
16. With a wrench, tighten the pressure bolt until the ball joint shaft pops loose from the steering arm. Wear eye protection. The ball joint can break loose suddenly and scatter dirt or other debris in your eyes.
17. 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.
18. Remove the cotter pin and radius rod ball joint nut
19. 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.
20. Use the ball joint remover as shown on step 15 to separate the ball joint and radius rod.
NOTE: If necessary, apply penetrating type lubricant to loosen the ball joint.
21. Remove the cotter pin and lower arm ball joint nut.
22. Install a 14 mm hex nut on the ball joint. Be sure that the 14 mm 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.
23. Use the special tool to separate the ball joint and lower arm.
NOTE: If necessary, apply penetrating type lubricant to loosen the ball joint.
24. Remove the cotter pin and the upper ball joint nut.
25. Install a 10 mm hex nut on the ball joint. Be sure that the 10 mm 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.
26. Use the special tool to separate the ball joint and knuckle.
NOTE: If necessary, apply penetrating type lubricant to loosen the ball joint.
27. Pull the knuckle outward, and remove the driveshaft outboard joint from the knuckle by tapping the driveshaft end with a plastic hammer, then remove the knuckle.
NOTE: Replace the bearing with a new one after removal.
28. Separate the hub from the knuckle using the special tool 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.
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 tools shown.
NOTE: Wash the knuckle and hub thoroughly in high flash point solvent before reassembly.
32. Press a new wheel bearing into the knuckle using the old bearing, a plate, the special tool and a 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 in the reverse order or removal, and pay particular attention to the following items:
- Be careful not to damage the ball joint boots when installing the knuckle.
- Torque all mounting hardware to the specified torque values.
- Torque the castle nuts to the lower torque specifications, then tighten them only far enough to align the slot with the pin hole. Do not align the castle nut by loosening.
- Install new cotter pins on the castle nuts after torquing.
- Avoid twisting the sensor wires when installing the wheel sensor.
- Before installing the brake disc, clean the mating surfaces 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.
NOTE: Make sure the front wheels are in the straight ahead position (mechanical neutral) after the wheel alignment, then let the ATTS control unit memorize the neutral position.
