Shops are reporting huge failure rates on ABS sensors in some late
model GM vehicles where the ABS sensor is integrated with the wheel
bearing/hub. These sensors are in two styles. One style bolts the sensor
directly on the wheel bearing. The sensor counts the notches on the ABS
tone ring inside the wheel bearing. The clearance between the sensor
and the tone ring is critical. The problem occurs when rust builds up
between the sensor and the wheel bearing. This phenomenon is called
"rust jacking," where the rust literally pushes the sensor upwards,
increasing the gap between the sensor and the tone ring to the point
where it reads intermittently. If you have this style sensor, remove it
and lightly sand the rust (lightly being the key word). Then apply a
light coat of marine grease on the bare metal and re-assemble. You may
want to try applying a thin bead of RTV silicone around the outer edge
to prevent water from getting under the sensor.
The second and more common style has the ABS sensor built into the
bearing/hub. This unit CANNOT be serviced. You must replace the entire
bearing/hub.
