Separate issues. First I am curious why the 01's howl. Mine is a dually and my friends is a single. They both howl at low speed turns. Second is the issue of turning the wheel when the brakes are applied. Let me say this is a real bother when you have a trailer you need to hook up or back up. It only happens when you are at a complete stop and trying to turn. As soon as you let off the brakes it turns. Oh and they are both 4x4.
