Air hammer is about the best way to get that bolt out unfortunately. The other side I would place the jack on it and try to lift it up. It should help you line it back up. If you can get that other side lined up, try disconnecting the driveshaft, shocks, and quad shocks and you should have enough space to pull the springs out.
