Sorry for your troubles but I know exactly why the nut backed off.
I have a really nice 1/2" impact gun and a 2 stage air compressor so I can really jack up the pressure when needed. It won't back off some headbolts rated at 120 to 150 ft/lbs of torque.
The stud you have on your ball is like 400 to 500 ft/lbs of torque.
