The Chevy Silverado has an anti-lock braking system (ABS) wheel sensor on each wheel that provides the wheel speed to the ABS controller. The ABS controller then uses that information to determine the amount of braking force to apply to that wheel. You may need to replace the ABS wheel sensor if it becomes clogged with debris, especially metallic brake dust.
Determine which ABS wheel sensor your Chevy Silverado will need. Make sure the new wheel sensor is compatible with your make and model of Silverado. All versions of the Silverado have had ABS since its debut in 1999.
Raise and support the vehicle. Remove the tire and wheel with a socket wrench. Disconnect the brake rotor with a socket wrench and remove the wheel speed sensor mounting clips from the frame, knuckle and upper control arm.
Unplug the electrical connector for the wheel sensor and remove the wheel speed sensor mounting bolt with a socket wrench.
Remove the wheel sensor from the wheel hub/bearing assembly by pulling it straight out of the bore. Do not attempt to pry the sensor out of the bore as this can break the sensor.
Clean the wheel sensor mounting surface on the hub with a wire brush to remove any corrosion. Apply a thin layer of wheel bearing lubricant to the hub surface and O-ring before installing the wheel sensor.
Install the new wheel speed sensor by reversing the removal steps. Ensure the sensor is seated against the hub and use a torque wrench to tighten the wheel sensor mounting bolt to 13 foot pounds.
