When I bought Tater, at least half of the nuts wouldn't budge, even using a 1" impact at 110PSI on the hose. I gave in and did it the semi-easy way. I took the hubs apart (needed to anyway).
I used a motorcycle/ATV lift to slide the rear duals, brake drum and hub off in one piece, then used an engine hoist to lift them into my small truck. Took them along with the front wheel-drum-hub assemblies to the local tire shop where they applies the "OMG that's HUGE" 2" splined truck impact wrench and popped them apart sweet as you please.
Upon realization that I could have done this SO much sooner, my sore back promptly cramped up in retailiation.
Since I use my old beast as a work truck I'll be taking the wheels off to rotate the rubber and do brake maintenance from time to time, so I'm not terribly worried about siezing. And if they do, that same shop has a mobile service that will come unscrew my fasteners for me.
