Wheel Speed Sensor: Service and Repair

Front Wheel Speed Sensor Replacement (2WD)

Removal Procedure

Caution: Refer to Brake Dust Caution.

Caution: Refer to ABS Component Handling Caution.

1. Raise and support the vehicle. Refer to Vehicle Lifting.
2. Remove the wheel and tire.





3. Remove the brake caliper bracket bolts (1).

Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.

4. Without disconnecting the brake hose, remove the brake caliper and bracket (2) as an assembly and support with heavy mechanics wire or equivalent.





Important: Note the location of the retainers for the wheel speed sensor to the upper control arm and the body to aid installation and ensure correct harness routing.

5. Release the retainers securing the wheel speed sensor wiring harness to the upper control arm.




6. Disconnect the wheel speed sensor electrical connector.
7. Remove the speed sensor electrical connector from the body.





Important: Note the orientation of the wheel speed sensor harness to the steering knuckle to ensure correct installation.

8. Using white or bright colored paint, mark the location of the speed sensor wiring harness to the steering knuckle.




9. Remove the wheel speed sensor harness bracket bolt (1).
10. Remove the wheel hub/bearing bolts (2).




11. Remove the brake rotor and the wheel hub/bearing as an assembly while routing the wheel speed sensor harness through the steering knuckle.




12. Using white or bright colored paint, mark the location of the wheel speed sensor harness to the wheel hub/bearing assembly.

Important: DO NOT lever or pry against the wheel speed sensor tone wheel under the wheel speed sensor. Lever against the wheel hub ONLY.

13. Using a suitable tool, pry or lever the wheel speed sensor off of the wheel hub/bearing housing.
Discard the wheel speed sensor.

Installation Procedure

Important: Align the wheel speed sensor harness with the reference mark on the wheel hub/bearing assembly.




1. Position the wheel speed sensor on the wheel hub/bearing assembly.
2. Carefully press the wheel speed sensor squarely onto the wheel hub/bearing assembly until fully seated against the lip of the wheel hub/bearing assembly housing.

Important: Align the wheel speed sensor harness with the reference mark on the steering knuckle.




3. Install the wheel hub/bearing and brake rotor assembly to the steering knuckle.




4. Install the wheel hub/bearing bolts (2).
Notice: Refer to Fastener Notice.

Tighten the bolts to 125 N.m (92 lb ft).

5. Install the wheel speed sensor harness bracket bolt (1).

Tighten the bolt to 20 N.m (14 lb ft).




6. Install the wheel speed sensor harness retaining clips to the upper control arm.




7. Install the wheel speed sensor harness connector to the body.
8. Connect the wheel speed sensor harness electrical connector.




9. Install the brake caliper and bracket assembly (2) to the steering knuckle.
10. Install the brake caliper bracket bolts (1).

Tighten the bolts to 175 N.m (129 lb ft).

11. Install the tire and wheel.
12. Lower the vehicle. Refer to Vehicle Lifting.
