Can a wheel bearing be replaced at the rear?
The front has magnets pressed into the wheel bearing so if the magnet cracks or is damaged the ABS speed sensor won’t read it properly! Unfortunately the fronts can only be fixed by replacing the bearings. The rear you can get already pressed into the hub so its a matter of replacing the whole hub.
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.
What to do if ABS wheel speed sensor goes out?
If the ABS wheel speed sensor was faulty, once the new hub/sensor is installed, and you drive the vehicle, the warning lights should go out. To determine what is going on, you can manually erase the trouble codes using an appropriate scan tool and if the warning lights stay off, then the problem is resolved.
What do you do when a wheel bearing hub is rusting?
This rusting process is called rust jacking. Sometimes you can remove the sensor, sand off the rust, and re-install the sensor. But other times you must install a new wheel bearing hub. After installation, you may think you’ve solved the problem.
Why are wheel bearing hubs equipped with wheel speed sensors?
When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside.
When does a wheel speed sensor need to be replaced?
Since the wheel speed sensor also monitors the anti-lock braking system on your car, it’s common for the ABS Light to illuminate when the sensor is worn out, disconnected, or has been struck by debris, which means you’ll have to replace the wheel speed sensor.
Can a wheel bearing be replaced on an ABS system?
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. The sad part is, you will most likely have to replace the wheel bearing with a new one.
When do you need to replace a wheel bearing hub?
But, if the tone ring is corroded or damaged, it must be replaced. In the case of sealed hub assemblies with the WSS and tone ring inside, the hub provides protection against external corrosion — or at least that’s the goal. But nothing is perfect, and when moisture seeps into the hub, it corrodes the tone ring.
