Application: Vehicles equipped with ABS (Anti-Lock Braking System) sensor rings located on the outer drive axle joint. See Fig. 1.
Problem: Intermittent ABS failure or trouble codes.
Cause: Rust can develop between the axle and the ABS speed sensor ring. The rust acts like a wedge and causes the ring to crack, creating a false or erratic signal that results in intermittent ABS operation.
Solution: Closely inspect the sensor ring for cracks or damage to the teeth. If any defects are found, replace the sensor ring or CV drive axle.
Note: Always remove any metal particles on the magnetic portion of the sensors.
