Ok I know that this has been a topic for a LONG TIME now. I'm experiencing a nasty shack on the left front tire. (i.e.. Drivers front tire) What happens is while parked the tire shacks forward and backward. When in gear and under throttle not a major prob. but it does rattle. Then stopped back to some rattles. and so on. I have talked to some friends and they suggested bearings, or steering pump. (I do notice a NOISY sound under the hood) So what I'm going to do is take the belt off and cruz around the block. So if any of you could give me more suggestions that would be helpful.
