Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello. I am pretty sure the issue you are having is a bad wheel bearing/hub assembly. I have seen them where, moving forward they grind and moving backwards they don't. The ABS light being on also helps to support that theory since the ABS sensor is part of the hub assembly. Are you able to raise the front end and attempt to wobble the wheels and see if either or both are loose? Also try spinning both front wheels while they are elevated off the ground and see if they make any grinding noise?
