1 1/2 turns from center to right and center to left is good. The more I've thought about it, I think the total (left to right) is 3 turns when the steering is stopped by hitting the stops on your axle---when everything is connected. The reason you want to move your steering wheel gently from side to side is so you won't damage the ball racks in your gearbox. Normally (when everything is all connected) these stops keep you from damaging anything by limiting the amount of travel in your steering. As I said at center 1.5 turns either way ought to have you at max left/right turn. Are your wheels pointing ahead when you are in the center of steering wheel travel?
