So what does it mean if it pulls to the left whether the valve is tapped all the way forward or backward? Plugged? Fluid not cycling back through the pump?
If you keep the engine running it will actually pull all the way to one side, then make wierd clunks as if the worm gear is jumping, then it will pull the opposite way......... and repeat........
When I tried adjusting the valve, I had the wheel locked, because I can just start with a switch, with key off, and it almost twisted my steering colum right off.
