When making turns, and the wheel is cut all the way, in my '87 3/4 ton V20, there is a loud and awful screech. Sometimes when turning the wheel from left to right, or visa versa (like an s turn), there is also tension like the truck does not want to turn. I was hoping you guy might be able to help me out. I was gonna go ahead and just change the steering pump, but figured I'd look for input first.
