I think that it would be easier to Turn with an ACTUAL Manual Steering than with a Disconnected Power Steering Pump. You could probably get a nice Pump from a Junkyard somewhere and replace that setup for a very modest cost. I had some Power Steering problems in my Truck and Spent the Whole weekend on it, but i was Glad i had done it in the end. Besides, i think a Rebuilt PS Pump is Pretty cheap too. Check you all your options first is my Advice.
