So while turning the wheel slowly to the right today it would ocassionally not move the motor. If i would move it faster, it would catch. To the left was fine.
Most of the time it's air or not full on fluid that causes issues. I know mine wouldn't always turn unles I would sort of jerk it to kick the valve then I could slowly turn it.
I have a slow leak in the Seastar steering on my sportsman. What your describing is what mine does when low on fluid. Probably all you need is the $20 quart of steering fluid.
