has the head sheard off so there is only a stud on?

If so then jsut take the wheel off, whack the stud with a lump hammer then use 2 nuts locked together or a mole grip to twist it out, or tighten it till it falls out the back of the hub.

If not, then erm.......easy outs are the only method and i hate them.

a bit of copper grease on the threads will stop them seizing in.
