Ya, that's all common sense. Not helpful for me. Please go back and reread my post.
As I mentioned, the shaft, and "QR" as you put it, unscrewed itself. It forced itself open.
Ive never liked the way it sat in the fork. It either bound, or was loose and the wheel flopping around. It never was solid and true and spinning freely.
I tried different combinations of tension on the hub nuts (don't know all the terminology) and QR, best I got was a compromise.
At this point, what needs to be replaced axactly?
