you need to do the socket trick.
remove the top bolt, but leave the other two but leave them threaded in a few threads. put the socket on one of them and what i do is use 1/2 inch socket and old ratchet, and turn the steering wheel until the ratchet head comes into contact with the knuckle, make sure it's seated well on the 12pt bolt, then turn the steering wheel with some force until you hear/feel the hub break free.
switch back and forth with the two bolts until it's completely off.
you can also use an extension, but i've only done it this way. comes apart every time. no matter how rusted or seized on they are.

i cant even get the 3 bolts that hold the hub assembly in place. one is stripped and the other two and rusted to hell. i tried to remove one and it broke my socket. idk why the **** they would use a 12pt bolt

If their stripped beyond a salvageable grip, he needs to cut the heads off and slide hammer the hub off. There just isn't a way around it. Anytime I get to a high load bolt like that, especially if it hasn't been moved in a while, I take a center punch and smack the head (dead center) a couple times with a 3lb sledge. That does wonders some times.

End up with a weakened joint and the ears on the yoke bent. There is use for a hammer. Sometimes the ears on the d.s. get sucked together and you can use a couple hits to spring em out. Not real hard though.

I just hammer them out with a socket in a socket. A skinny, deep socket to hammer one side and a HUGE socket (36mm) to "catch" on the other side. Pretty straight forward, usually takes no longer than 10 minutes total.
I always pull the axle and it usually takes me no longer than 40 minutes for a side, as long as you dont run into any problems.
Leave the Jeep on the ground to break the hub nut (if you have rims that allow this) as its MUCH easier to do than putting it in 4WD and trying to break it on a jack stand.

I usually have the best luck with the hammer and vise method, doing things the "right way" by the book with either a hyd press, or with the C clamp balljoint/U joint press I have "sprung" yokes, as well as with the hammer on anvil or hammer on vise methods.

on my old chevy I just tightened the yolk nut about Half a turn, whenever I felt that it was getting loose. got me another 70,000 out of it before it locked up.

Ive done dozens with the hammer and socket method, as Im sure others have as well. Is the the RIGHT way? Maybe not, but it works. Im not talking about smashing it with a sledge, Im talking about being careful and hammering them just like like like thousands of other people do just fine. You gotta do what you gotta do. The hammer and socket method has worked for me this long so Ill continue doing it as Im sure others will as well. Its a pretty easy, straight forward and safe way to change a U-Joint without buying specialty tools.
