C 3500 HD Truck 2WD V8-8.1L VIN G (2002)
Important: It is not necessary to replace the sensor mounting bracket unless there is visible damage or distortion to the mounting bracket.
8. Remove the wheel speed sensor (3) from the mounting bracket (4).
Installation Procedure
Notice: The wheel speed sensor used on the C 3500HD models is adjustable by means of slots provided in the mounting bracket. The sensor must be
properly adjusted in order to provide the correct air gap between the wheel speed sensor and the tone wheel. If the sensor is not properly adjusted, the
tone wheel may hit the wheel speed sensor, or the output from the wheel speed sensor may be low, missing or erratic. Follow the procedure outlined
below to properly adjust the front wheel speed sensor.
1. Install the wheel speed sensor (3) to the mounting bracket (4).
2. Install wheel speed sensor to bracket mounting nuts (5).
3. Run down the nuts but do not torque. The wheel speed sensor must remain loose and move along the slots in the bracket.
4. Place the front hub and rotor assembly on a flat surface with the tone wheel facing up. Take care not to damage the wheel studs.
5. Mark the position of the rotor relative to the hub so the rotor can be installed in the same position later.
