At idle i have a vibe in the steering wheel and the break pedal.I can feather the pedal and the vibe cont, to about 1800 rpm.any ideas?
I have the exact same thing on my 1999 f350... How did you finaly fix the problem???:bump: Updating on problem, Mike put the new box on to no avail, Have looked at truck with him and it has a slight noise(slight rattle) to it that sounds to me as if it is coming from down below the turbo somewhere.When you crawl underneath noise sounds as if coming from up higher (not at bottom of motor)and towards rear of engine.Dealer told him something in the hydra-boost system , ie. power steering pump,steering box,hydra boost.Have replaced the first two components and nothing.Dealer is qouting 2400.00 for a hydra-boost? Anyone else have any more input on this. We are also starting to lean towards tourqe converter or flywheel as previous responder said. Only thing is vibration does not get worse at speed????:dunno:
