i tried to do mine about 4 years ago with no luck. i ended up taking the whole front end out and having them pressed out/ in by a shop for about 120 and i think the joints were about the same. i think it is actually time to do it again if you find a good way to do it let me know and we can have a ball joint party.
if you have a torch, bucket of ice, some ultra dawn, a med. or large floor jack, a BFH and 2 people, it's actually not that hard! after everything else is taken off, you put a jack under the joint and jack it up just enough to get all the weight on it. heat up the outside of the C that surrounds the joint until it's cherry red. then beat it LIGHTLY on the side with BFH. it will come out, and if it doesn't, take off the jack and beat the h-e-double hockey sticks out of that joint in the direction it's supposed to come out. (one of the joints comes out in the wrong direction to use a jack on it, but works great for pressing the new one in) now both joints are off.
now here is the part that has to be done RIGHT. if you are quick enough, you won't have to reheat the hole. if you don't think you are, then just reheat it. before putting the new joints in, they have to have set in a freezer for at least a couple of hours, and then buried in a bucket of ice while you're taking the old ones out. when you re heat the hole and get ready to drop in(usually literally) the new joints, the metal has to be barely red. squirt soap on the new joint, shove it in the hole and beat/ press it in ( with a socket on the flat spot, not the stud) for about 5 seconds. then grab the ice bucket that that joint came out of and shove it over the whole thing, and hold it there for about 3 minutes. PRESTO! it's done!
now you're probably thinking that there is a risk of the plastic inside of the joint melting or the hole could crack. follow the directions, and you will be fine. the metal will evenly cool/ equalize temp in ICE NOT WATER because ice has to go through 2 phase changes while absorbing the heat. if you were to stick it in straight water the C would probably crack from cooling down too fast. my old man uses that method on farm equipment/vehicles so he doesn't have to buy a dozen or so tools for different applications. he helped me do it on mine a while back.
