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.
