Good luck!
I asssume you can't remove the tyre with the wheel in-situ? It's difficult, but not impossible.
To get wheels off in the past I've had to fabricate a puller, and drill holes in the wheel to put the puller legs through. If you go this route, apply serious heat (from a welding torch) and apply as much pressure as you can with the puller. Destroy the wheel if you have to - it's cheaper than a transaxle.
