text:  Is it a Super Duty? Yes. Yeah, then you've got Super Duty with a gearbox, but there's still electronic variable orifice steering to control the pressure on that, if I remember right, on that one. They just have issues on the ones that are dependent on the truck. If it's like a work truck type where you've got a gearbox and you've got a pump and that's it, more than likely the problem is in the pump. How many miles are on it?
