John, go to the autoparts store and buy a can of "PB Blaster". Spray it all over the hubs and spinners (this stuff won't ruin the wheels, but wipe away any overspray) and let it soak in for 24 hours. Trust me...this stuff works wonders on rusted bolts, etc. Also get yourself a good, solid 1' length of 2x4. You can place one end on a spinner ear and beat the other end with a rubber mallet or urethane mallet. This works especially well in the back where you have a deeper offset to the wheel and it's harder to get a good hard whack on the spinners.
