2. Remove wheel and tire.
3. Remove brake drum or disc brake caliper and rotor from hub and bearing.
4. If equipped with antilock brakes, perform the following:
a. Remove secondary (yellow) retaining clip at rear of wheel speed sensor head.
b. Push up on metal retaining clip until it bottoms. This will release wheel speed sensor head from hub and bearing.
c. While holding metal clip up, pull back on wheel speed sensor head removing it from hub and bearing.
5. Remove the 4 bolts attaching the hub and bearing to the rear axle.
CAUTION: Corrosion may occur between the hub and bearing, and the axle. If this occurs the hub and bearing will be difficult to remove from the axle. If the hub and bearing will not come out of the axle by pulling on it by hand, do not pound on the hub and bearing to remove it from the axle. Damage will occur. Use the following procedure.
6. If the hub and bearing cannot be removed from the axle by hand, use Remover, Special Tool 8458 and the following procedure to press the hub and bearing out of the axle.
a. Remove the two outboard spring plate bolts.
b. Thread Threaded Guide Pins into hub and bearing mounting bolt holes.
c. Using the spring plate bolts, install the Screw Mount, Special Tool 8458-2, as shown. Mount the Screw Mount to the spring plate with the tool number facing the hub and bearing and the beveled edge on the bottom facing the spring, otherwise the Forcing Screw will rub the spring plate when installed.
d. Place Push Plate, Special Tool 8458-1, on ends of Threaded Guide Pins
e. Place a dab of grease in dimple of Push Plate.
f. Install Forcing Screw, Special Tool 8458-3, through Screw Mount from rear.
g. Tighten the Forcing Screw up against dimple in Push Plate and press hub and bearing out of axle by continuing to tighten screw.

7. Remove the hub/bearing from the rear axle and brake support plate.
INSTALLATION - FWD
1. Install the 4 hub and bearing to axle mounting bolts into the holes in the flange of the rear axle.
2. Install the rear brake support plate on the 4 mounting bolts installed in the flange of the rear axle.
3. Align the rear hub and bearing with the 4 mounting bolts and start mounting bolts into hub and bearing. Tighten the 4 bolts in a crisscross pattern until the hub and bearing and brake support plate is fully and squarely seated onto flange of rear axle. Tighten the 4 mounting bolts to a torque of 129 Nm (95 ft. lbs.)
NOTE: If equipped with antilock brakes, make sure wheel speed sensor stays clean and dry as it is installed into the hub and bearing cap.

a. If metal sensor retaining clip is not in the neutral installed position on hub and bearing cap, install from the bottom, if necessary, and push clip upward until it snaps into position.
b. Install wheel speed sensor head into rear of hub and bearing aligning index tab with the notch in the top of the mounting hole. Push the sensor in until it snaps into place on the metal retaining clip.
c. Install secondary (yellow) retaining clip over wheel speed sensor head and engage the tabs on each side.
5. Install brake drum or disc brake rotor and brake caliper.
6. Install wheel and tire. Tighten the wheel nuts in the proper sequence to a torque of 135 Nm (100 ft. lbs.).
7. Adjust the rear brakes as necessary.
