Wishbone front bush bolt to subframe nut retainer?

[mattgreene]

Has anyone come accross this problem before? undo the front bolt on the wishbone and it just turns :-( not really sure the best way to get it out now, so much for a simple job!! Got the wheel off the wiggled the drive shaft, the bearing collapsed too, just to add to the fun!
Ideas on the best way to remove the bolt and also ideas for refitting too please
