Well you have the hub puller, might take a couple days, tighten it down real tight, use a piece of metal between the puller and the end of the axle, so as not to damage the threaded end of the axle, when you take off the nut on the axle put it back on at the end of the threaded part of the axle, this keeps the drum and puller from becoming projectiles when they break lose, and use a really (really) big hammer. tighten, bang real hard, tighten and repeat. keeping the pressure on it and repeating over a period of time it will eventually "pop" off. I did this (there's posts on this, on this site) and, one morning after a couple days, I walked out to my garage and it had popped off. Hope this helps
