Well, I hear a sort of grinding sound, almost sounds like I'm dragging some sort of metal piece under the car. sounds like it is comming from the rear of the car. I only hear the problem when I am rolling. I already engaged the trans with the parking brake on and I didnt hear it either.The car doesnt pull at all in any direction so I would think that it ruled out the rear drums. My conclusion was that one of my rear wheel baerings is going out. Anyone have any other ideas
