Stuck Lower Ball Joint

Have a 2013 Wrangler Sahara. Replacing ball joints (and axle bearings) to get rid of the death wobble. On passenger side, upper ball joint came out with some convincing. Lower ball joint is a different result (seems to be not uncommon). Have used Autozone loaner ball joint press (bought pipes sized so the lower ball joint will drop through), tightened with breaker handle and 3' pipe extension. Won't budge. Put Break 'R Loose on for overnight. Still nothing. More pressure, nope. Beat with a small sledge while pressure is on, nope. Tried propane torch heat for 2 minutes, bang on yoke with short sledge, no movement. Thinking of trying 4-ton hydraulic bottle jack, which will fit within the yoke; will put a large nut underneath the jack so it pushes the joint through (plate under jack so nut doesn't damage the jack body, will also require a plate for the upper ball joint hole). Will pressure damage the wheel yoke? Can Jack be inverted so the piston ram pushes on the ball joint? 4 tons enough (willing to buy 8 or 12 ton, $30-$35 at Harbor Freight)?

Make sure you're pushing the ball joint in the correct direction. Is there a retaining ring holding the BJ in place?

I followed the same youtube video. See pics (old yoke showing old BJ, and new ball joint w/grease fitting); no retaining clip. My concern with using a hydraulic jack is it will use the upper arm of the yoke as the resistance for pushing against the one I want to remove. Will it take that much pressure (a regular ball joint press is 20 tons; I'm considering a HF 12 ton). Sorry, it's late, I couldn't figure out how to resize.

Try a propane torch on the outer areas surround the ball joint.

assuming you have a good C press, like the one in the video. When you have it at high torque and it dont move i use a 2 pound brass hammer. and smack the c. Since it is brass you can hit it as hard as you like. seems to always pop loose. if that dont work>heat and hammer keep the torque on the clamp but dont bend it if you can, some low end ones can bend.

my 12 the lowers had to use the the hammer and i have a good C clamp.
