I had a friend do a 700r/208 change to a 400/203. Suddenly my powersteering makes noise and is hard to steer, and I got a flat tire (just kidding about the tire). The motor is a 1993 model 454.... I thought power steering pumps just slowly started leeking on the driveway, but never all of a sudden hard to stter, noise and no leaks? Thanks in advance all you CK5rs - rezalB Built for a purpose.
