Wheel Speed Sensor Replacement 4WD

1. Raise vehicle.
2. Remove tire and wheel. Refer to Tire and Wheel Removal and Installation .
3. Remove brake caliper. Refer to Front Brake Caliper Replacement .
4. Remove the hub and rotor. Refer to Front Brake Rotor Replacement .
5. Remove wheel speed sensor mounting clip on the control arm.
6. Remove wheel speed sensor mounting clip on the frame rail.
7. Disconnect the wheel speed sensor electrical connector (2).
8. Remove the sensor mounting screw (5).

Important: The wheel speed sensor mounts into a bore that leads to the center of the sealed bearing. Use caution when cleaning or working around the bore. Do not contaminate the lubricant inside the sealed bearing. Failure to do so can lead to premature bearing failure.

NOTICE: Carefully remove the sensor by pulling it straight out of the bore. DO NOT use a screwdriver, or other device. Prying will cause the sensor body to break off in the bore.

NOTICE: Do not attempt to remove the stainless steel shim from the bearing assembly. The shim is permanently attached. If the shim is damaged or bent, replace the bearing assembly. Failure to comply will result in diminished sensor and ABS performance.

9. Remove wheel speed sensor from hub and bearing assembly.

Important: The new speed sensor will have a new O-ring. Dispose of the old O-ring. Lubricate the new O-ring lightly with bearing grease prior to installation. You may also lubricate the sensor just above and below the new O-ring. DO NOT lubricate the bore.




1. Install sensor into the hub and bearing assembly (6).

Tighten
Tighten the sensor mounting screw (5) to 18 N·m (13 lb ft).

Important: The new sensor has new mounting clips already installed on the wire. DO NOT reuse the old clips.

2. Connect the wheel speed sensor electrical connector (2).
3. Install wheel speed sensor mounting clip to the frame rail.
4. Install the wheel speed sensor mounting clip to the control arm.
5. Install the hub and rotor. Refer to Front Brake Rotor Replacement .
6. Install brake caliper. Refer to Front Brake Caliper Replacement .
7. Install tire and wheel. Refer to Tire and Wheel Removal and Installation .
