I thought about this and I can think of a way that will work.
remove the axle and bearings.
get 2 oak blocks, drill a hole that is the size of the hub center body in the middle of the two pieces so you have a way to clamp the hub into your vice.
you can tape up the hub if you want to prevent scuffing. tighten down to beat HECK.
then take the 10 mm allen (which I think is the tool for the freehub attach nut), put it in the hub.
Get an air powered impact wrench and break the nut loose.
I think you need the peak torque and shock impact to break it loose.
Strap wrench / inner tubes etc probably not going to work.
that's the way I'd do it
