You aren't going to like this but it will work. Remove your wheel pulling hardware and then heat up the hub of the wheel from the inside using a propane tourch turned down low. Be prepared to burn off the insulation on your horn button ground wire. (you can remove it and repair the burned off insulation later). After you get the hub plenty warm, QUICKLY replace the puller hardware and apply preassure. Give the center puller screw a solid wack with a brass or lead hammer. The wheel will come off.
HINT: Loosen up the steering wheel nut but do not remove it from the end of the shaft. This will prevent you from distorting the ends of the screw threads on the shaft while you are applying preassure and giving the puller center screw a solid whack.
