Service Procedure

1. Raise the vehicle on an appropriate hoist.

2. Remove both front wheel mounting nuts, then both tire and wheel assemblies.





3. Remove and discard the hub nut from the axle halfshaft stub shaft (Figure 1).





4. Remove the brake pads, brake caliper and brake caliper adapter as an assembly (Figure 2).

CAUTION:
Do not allow the brake caliper and brake caliper adapter to hang by the brake hose. Use a strap to keep the brake caliper and the brake caliper adapter supported.

5. Remove the front brake rotors.





6. Remove the screws fastening the brake shield to the steering knuckle, then remove the brake shield (Figure 3).





7. Remove and discard the wheel speed sensor retaining bolt (Figure 4).

8. Carefully pull the wheel speed sensor from the bearing housing (Figure 4).

9. Push in on the end of the halfshaft stub shaft, pushing its splines out of the hub splines.





10. Remove the four hub and bearing mounting bolts from the rear of the steering knuckle (Figure 5).

11. Remove and discard the hub and bearing from the steering knuckle.





12. Clean the hub and bearing mounting surfaces on the steering knuckle and the halfshaft stub shaft splines. They must be smooth and completely free of foreign material or nicks prior to installing the new hub and bearing assembly (Figure 6).

13. Make sure the isolation washer is located on the halfshaft stub shaft before installing the new hub and bearing assembly (Figure 6).

NOTE:
The isolation washer is bi-directional, and can be installed in either direction.





14. Apply a light coat of Mopar Anti-Seize (P/N 05012249AB) or equivalent to the halfshaft stub shaft splines (Figure 7).





15. Apply a light coat of Mopar Anti-Seize (P/N 05012249AB) or equivalent to the hub mounting surface (Figure 8).

16. Install the new hub and bearing assembly onto the halfshaft stub shaft and into the steering knuckle until squarely seated on the face of the steering knuckle.

17. Install the four hub and bearing mounting bolts from the rear of the steering knuckle. Progressively and equally tighten all four mounting bolts using a crisscross pattern. Tighten the four hub and bearing mounting bolts to 45 ft. lbs. (65 N.m).

18. Remove the protective rubber plug from the wheel speed sensor hole in the hub and bearing assembly.

19. Insert a small amount of wheel speed sensor lube onto the sensor and in the sensor hole on the bearing housing.

20. Install the original wheel speed sensor into the sensor hole in the bearing housing.

CAUTION:
When installing the wheel speed sensor, do not rotate sensor, as this may cause the sensor to rub on the tone ring and be damaged.

21. Install the new wheel speed sensor retaining bolt and tighten the bolt to 71 in. lbs. (8 N.m).

22. Install the brake shield onto the knuckle. Install and tighten the three mounting screws to 71 in. lbs. (8 N.m).





23. Clean the rotor-to-hub mating surface (Figure 9).

CAUTION:
Failure to clean the rotor-to-hub mating surface could cause brake pedal pulsation.

24. Apply a light coat of Mopar Anti-Seize (P/N 05012249AB) or equivalent to the rotor pilot hub on the wheel hub.

25. Install the front brake rotor onto the hub.

26. Install the disc brake caliper and the brake caliper adapter assembly. Tighten the adapter bolts to 125 ft. lbs. (169 N.m).

27. Pump the brake pedal several times to ensure the vehicle has a firm brake pedal.





28. Install the new hub nut on the end of halfshaft stub shaft. With the aid of a helper, apply the brakes to keep the front hub from turning while tightening the hub nut to 160 ft. lbs. (217 N.m) (Figure 10).

CAUTION:
Always install a new hub nut. The original hub nut is a one-time use only nut and must be discarded when removed.

29. Repeat Steps 3 through 28 on the other front wheel.

30. Install the tire and wheel assemblies. Install and tighten the wheel mounting nuts to 100 ft. lbs. (135 N.m).

31. Lower the vehicle from the hoist.
