Component Replacement
When the wheel speed sensor is replaced, the sensor spring clip must also be replaced.
Installation
1. Connect the sensor cable to the chassis harness.
2. Install the fasteners used to hold the sensor cable in place.
3. Apply a WABCO-recommended lubricant to the sensor spring clip and sensor.
4. Install the sensor spring clip. Verify that the spring clip tabs are on the inboard side of the vehicle.
5. With the tabs on the inboard side, push the sensor spring clip into the bushing in the steering knuckle
until the clip stops.
6. Push the sensor completely into the sensor spring clip until it contacts the tooth wheel.
7.
Fasten the sensor cable with the first fastening point four-inches (100 mm) away from the sensor and
then every 12-inches (304.8 mm) afterwards. Correctly bundle and store any excess cable in the
sub-frame at a minimum of a 0.6-inch (15 mm) radius.

brake shoe. Remove the wheel and tire assembly from the axle.
4. Remove the sensor from the mounting block. Use a twisting motion if necessary. Do not pull on the
cable.
5. Disconnect the sensor cable from the chassis harness.
6. Remove the sensor cable from any cable clamps or clips.
