I had to idle along, when I tried to go faster the steering wheel would shake bad.Were you under power, going fast or just idiling along?
The PS pump does turn smoothly if I go in Idle speed, but once I throttle down the steering wheel shakes bad.When you say inboard, you really mean I/O right? If so, I would suggest the power steering system has an issue. Is the fluid level correct? Does the PS pump turn smoothly when the engine is running?
