O.K.....I finally managed to get my bad wheel hub replaced. Went very well thanks to your helpful threads on here. I put the National brand on, replaced pads and rotors with ceramic pads etc.....The questions I have are: If I fixed the problem of a bad wheel speed sensor (had it scanned and that was the wheel I fixed), shouldn't the light go off automatically, or do I have to have it reset with a scan tool??? Also, I had it scanned with a MAC scan tool before the repair and his was showing a low voltage to the ABS pump. I was told that I needed to replace the hub first. Now I'm wondering what the low voltage problem is and if that was related or not to the bad hub??? Thanks for you help in advance!!!

I think it will reset after a number (?) of restarts, but depending on what you were charged for the scan I would take it back there, have it reset and rescanned.
