I run an 87 yj and the power steering gearbox has give up the ghost. It leaks and has become so loose it's scary. I've installed new U Joints, tie rods, ball joints and bearing assemblies in both wheels so I know it's the box. Question - is the box from a Cherokee the same as the YJ? I have access to one but don't want to take it off if it's not going to work. Hope someone can help.. Thanks.
