[quote ='Zoiders']How much did you pay for the bike?
The only reason I ask is because a cheap cup and cone wheel can unthread it's self, the lock nuts and cones tend to be a bit a bit soft so the threads go baggy and not able to take the torque.[/quote]
Seen something very similar to this before and it was a bearing cup that had fractured, skewing the wheel over to one side. It took quite some time to work out what the problem was and the crack in the cup was only visible when I disassembled the whole hub and cleaned out the cups of grease. Worth checking.
