Well it's all gone quiet out there, so I shall pitch in, although I should say I have not yet had occasion to work on my rear hubs.
The taper on the shaft appears to me to have been lapped more than once in its lifetime and so the hub now is too near the centre line of the car.
The hub may be riding up on the woodruff key before it seats itself fully on the taper, which would explain it coming loose.
I don't know whether anyone has done either of these successfully, but two solutions come to mind (apart from shelling out for new half shafts), firstly to spray weld the tapers and turn new ones. Secondly, a bodge could be to cut a trapezoid shape from shim stock and sit this around the taper, bracketing the woodruff key.
If you are determined to stop the nuts rotating in their present position, there is just enough meat in the castellated bits to drill a chord to miss the threads and then wire them on through the split pin hole, à la military land rovers. If you're going to put a washer under the nut it would need to be hardened.
Good luck!
