Okay, so I don't know the darndest thing when it comes to abs. I took my car into a gm dealer, got it coded and they said that I'm getting codes thrown from the from left wheel sensor. abs, trac control, and tire press lights all stay on while driving. I don't know anything about this, so I was wondering. Do I need to change the whole bearing, or is it possible (easy) to change just the sensor alone. Does anybody know part numbers? and does anybody have a walk through or know here I can grab one?
