I had the same problem, twice. The first time I took it to a shop and paid several hundred dollars for them to finish replacing the axle for me. The second time, I tried to remove it, and once again frozen solid.
I broke my puller
I broke my BFH
I read that even a 20 ton press does not always work, and SOA recommends replacing the hub and axle as a unit because they are not "meant to" come apart.
So I left the CV in the hub, undid the inner connection to the trans, took off the bearings and races, and was able to replace both boots from that end.
As long as the bearings are OK, I will do it this way from now on. I wish I had thought of this the first time before I threw all that money at it. It's so obvious now.
