I have a 2001 and for the life of me and my mechanic, we can't figure out where this noise is coming from. It started on the passenger side front and rear, when I had new tires put on it changed to the driver's side. It is a loud grating noise at slow speeds forward or backward. Goes away after you hit 3rd. Its intermitant but very noticable, of course, it never does it when I bring it in to the shop. My neighbor suggested something called brake drag. Any ideas?
