Q: My ABS light went up

asked by on

A mechanic has test it with a computer , says the right front sensor was broken, should I replace the sensor or the whole hub? Thanks.

My car has 145000 miles.
My car's transmission is unknown to me.

In my experience the hub and sensor both needs to be replaced. The sensor will most likely break off when trying to remove it. If you do manage to get it out, the front hub bearings wear will cause erratic problems with the new sensor. This is why the two parts should be replaced together and doing so will fix your problem. If the right front is proven to be bad that means that the left front will fail soon as well. They both have high mileage on them and the same amount of wear. If you decide to get this fixed, consider YourMechanic, as a certified technician can help you with the replacement of your wheel hub and sensor.

You should jack up that wheel and wiggle the wheel to see if there is a loose bearing? If it is not loose then you most likely have a warped brake rotor on that side.
