This gave me a better view of the nut that I was gradually rounding off but still not enough room to work

Releasing the top bolt let the whole hub drop supported just by the ABS wire and the brake hose. A quick grab for a spare axle stand saved the day! I now had lots of room to work. It still wasn't easy but at least it was not possible.

I have now taken a break before continuing with the ball joint breaker to soak my thumb joint in iced water. Yes, I hit just smack my thumb joint with a lump hammer. Ow!
