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?
