okay, so I I've been trying to pull the rear passenger side hub on my cj3a. I sprayed kroil on the axle stud and the puller bolt.  after installing the puller and tightening down the lug studs, I proceeded to tighten the puller until I could do it no more by hand.  then I started hitting the attached adjustable wrench handle (because I don't have the handle that goes on the back of the puller) with a small sledge.  it didn't seem to budge.  so then I went to a long handle sledge, alternating back and fourth between tightening up the puller, and hitting the back of the puller bolt.  I have put what I consider to be a massive amount of pressure on the axle stud.  I fully expected to see the gap between the drum and the backing plate to increase, but no change so far.  at this point, I'm wondering what to do next.

After I read your first post I was formulating a warning to you in my head. By the time I got to your follow-up post I realized it was too late. Here it is anyways: HOLY COW! BE CAREFUL! 

As you found out the rear hubs have a tendency to launch across the garage (or into your shins, pets, other vehicles that may be parked nearby...). Do yourself a favor next time and leave the axle nut loose but still in place. It will contain the hub if it tries to fly away.

And yes, you need a BFH and a lot of oomph behind your swing. Here's my hub puller. I did not personally inflict all of the damage on it but you can see from the wear it's meant to really be pounded on.

You guys both did better than me. On my first attempt at this after a couple days of messing around with all the wrong tools I threw in the towel and took the entire axle down to the machine shop. They removed both hubs....for roughly the same amount of money it would have cost me to buy the right puller in the first place.  Live and learn 

glad it didn't get stopped by your shin,   that would leave a mark
