I've been hearing some grinding in my wheel area recently and I was told my brakes were fine. Well today the noise was especially bad, but when I made a sharp left turn the noise completely went away until I straightened out my wheels. Someone told me that it is definitely my wheel bearing that is bad. Also, I jacked up the front and spun the wheels and they barely spun 1/4 of a turn on their own then they stopped. How would I know if the bearings are the problem? also are there any other problems that would cause these symptoms?
