What to do when your abs light comes on after a wheel bearing is replaced?
If you have an ABS light on after wheel bearing replaced, you may have to also replace the other wheel bearing hub. Car makers sometimes install the toothed tone ring inside the wheel bearing hub and mount the wheel speed sensor on the outside of the hub.
Why is my abs light on and Trac off?
Here’s why: Older ABS braking systems used a steel toothed ring and a magnetized wheel speed sensor. As rust accumulated on the tone ring it would throw debris onto the magnetic sensor and that debris would interfere with the signal, causing the ABS to activate prematurely. GM changed the wheel speed sensor and tone rings in these vehicles.
When does the ABS brake light come on?
If any of the teeth are damaged or missing, the ABS brake light will come on, warning the driver of a problem. The new style ABS systems use a magnetic encoder built into the wheel bearing, and if the wheel bearing is installed backward with the encoder facing out, it won’t take long before your ABS light is on and your stress level goes up.
Can a new wheel bearing cause false activation?
The new bearing will have little to no play; the remaining hub has acceptable play, but can still affect signal strength. Again, the difference in signal from side to side may be enough to trigger false activation.
