Repair Procedure

1. Raise the vehicle on a hoist.

2. Remove the tire/wheel assembly from the side of the vehicle creating the noise.

3. Remove the disc brake caliper slide pins.

4. Remove the disc brake caliper.

5. Support the caliper with a wire from a suspension component.

CAUTION:
DO NOT ALLOW THE BRAKE HOSE TO SUPPORT THE WEIGHT OF THE CALIPER.

6. Remove the disc brake rotor retainers and remove the rotor.





7. Remove the axle spindle nut (Figure 1).

8. If equipped, remove the four wheel Antilock Brake System (ABS) front wheel speed sensors.

9. Remove the hub/bearing mounting bolts from the steering knuckle.

10. Slide the hub/bearing out of the steering knuckle and off the axle.





11. Inspect the steering knuckle to ensure that the knuckle has a 450 chamfer on the outer edge of the hub/bearing attachment hole (Figure 2).

12. If the 45° chamfer is on the steering knuckle, proceed to the Step 14. If the 45° chamfer IS NOT on the steering knuckle, proceed to the next step.

13. Replace the steering knuckle (see Parts Required section). For information regarding steering knuckle service, refer to the appropriate 2000 Service Manual, Group 02, Steering Knuckle Removal/Installation procedures. Once the steering knuckle has been replaced, proceed to Step 14.

14. Install the new hub/bearing assembly (see Parts Required section) into the steering knuckle. lighten the bolts to 166 N.m (123 ft. lbs.).

15. Install the disc brake rotor.

16. Install the disc brake caliper/shoe assembly over the rotor and into the ledges in the steering knuckle. Be sure the ends of the brake shoes are properly seated on the slide surfaces of the ledges.

17. Align the caliper in the adapter and install the caliper slide pins. Tighten the slide pins to 30 N.m (22 ft. lbs.).

18. If equipped, install the four wheel ABS front wheel speed sensor. Tighten the bolt to 18 - 25 N.m (160 - 220 in. lbs.).

19. Install the front axle nut. Tighten the nut to 235 N.m (173 ft. lbs.).

20. Install the wheel/tire assembly.

21. Perform steps 2 through 12 on the other side of the vehicle. If the 450 chamfer IS NOT on the steering knuckle, the steering knuckle and hub/bearing assembly must be replaced, proceed to Step 13. If the 45° chamfer is on the steering knuckle, unless the bearing has failed, neither the hub/bearing assembly nor the steering knuckle needs to be replaced. Re-install/replace the hub/bearing assembly into the steering knuckle. Tighten the bolts to 166 N.m (123 ft. lbs.) then proceed to Step 15.

NOTE:
STEPS 2 - 12 MUST BE PERFORMED ON BOTH SIDES OF THE VEHICLE.
