You have the nut off right?

Can you pull the wheel back in the swingarm?

Put the nut back on, backward. Turn it on the threads until it's just flush with the end of the bolt.. Still loose, but covering the end of the threads.. Then smack the hell out of it with a sledge hammer...

It should move.

Then make sure you put a bit of grease on the axle when you put it back together, so this won't happen next time.

Place some blocking under the swingarm, next to the other end of the axle. Take the weight off, and brace the blow.

+1 on what foxforks said. Lay the bike on its side and place a wooden 4x4 block under the swingarm right next to the axle. Then get a BFH, (Big Freakin Hammer) and smack it.

If you don't back up the swingarm you will lose much of the effect from the hammer when the swingarm flexes.

You can remove the swingarm and wheel from the frame and use a 'BAP' (Big Ass Press) to press the axel out. Chances are, you will destroy the hub since your axel is most likely rusted/galled to the bearing or the center spacer sleeve.

This is why it is so important to do basic maintainance on your bike. Things like removing the wheel bearings and re-greasing them periodically. You could also try heating the hub with a torch. This will expand the bearing and maybe release the grip on the axle.

Yeah, 89er's right. Some heat on the hub and a press is about the only option that won't end up ruining the swingarm too. Pounding on things is generally a bad idea. My bet would be that the spacer inside the hub (between the bearings) is seized to the axle. I try to get mine apart for grease at least a few times every season. It can get expensive to fix once it ends up like yours. Good luck, hopefully it works out good for ya!
