    A closer look at the ball screw setup from the steering box. Please note that I’m completely wrong about the direction reversing by flipping the screw 180deg. The thread itself would have to change from a right hand thread to a left hand thread to reverse the direction. Sorry for the erroneous info! :) Thanks Eugene!
