Got a chance to throw a jack under the truck today. With both front wheels off the ground the effort is the same in either direction-tight any very easy to turn. Turning right, the pump will whine/hiss when the steering hits the stop-not an abnormal whine, but what you would expect. Wheels to the left on the stop there is no sound from the pump. Is my control valve bad or the power ram? It does not creep to one side like a Corvette will if the control valve needs adjusting, so I don't think adjustment is the issue. I'm assuming that if I've got ANY assist the pump is good. The box doesn't have any slop and with the wheels off the ground I can't tell any diference in effort, so I don't suspect the box...Donman, why did you say the box was bad? What "internal problem" could it have.
