Am sure your shimmy is caused by no pressure. With pressure, the power cylinder acts as a damper which isn't there now and with the steering wheel holding the pitman arm still but connected to the valve, the valve body is connected to wheels and is free to move the 1/4 inch or more movement range because there is no pressure on the valve to keep it centered and stationary.
