My 97 F-350 DRW (109k) is making a chirping sound at low speeds under load. I notice it the most when I am pulling a trailer, but it will do it empty starting from a stop and going up a hill. Does it in either forward or reverse. Don't really notice it after 15 mph. It sounds like it is coming from the rear end, but its tough to tell. Anyone have any ideas of what to do?
