Here is what I found. To be clear, when parked, I can easily move the steering wheel 45 degrees. Call it 22.5 right and 22.5 left before meeting resistance that is more than “ finger pressure”. The coupler, box, front suspension are all tight, idler arm as well. What I see as flexing or moving without moving the pitman arm is the sector shaft. Small leaking of lube at that sight. This YouTube video shows what I see. How to proceed next?
Looks like it's time to rebuild the steering box, that slop would be coming from the bottom bushing or bearing (depending on the style of the steering box).
