Cut the Ball Joints off with a torch to get the knuckle out of the way. Beat the hub bearing out with a 12lb hammer (you will need new bearings), being careful not to break the knuckle (I now own a new knuckle on the passenger side).
Use the large C-Clamp style ball joint tool, a large ratchet, a 10' pipe, and two big guys. On the bottom, make certain you remove the snap ring from the top of the BJ. Setup the clamp to push down, and get it as tight as you can with the ratchet. Now, using the 10' pipe, keep tightening until you can not move the ratchet. Get a second person, and both pull on the ratchet. Once the C-Clamp tool bends to a point where it looks like it is going to explode (stand back), if you are lucky, the BJ will all the sudden blow out the bottom.
When you replace, grease or anti-seize everything. On the knuckle, take a angle grinder with scotch-brite pads, and thoroughly remove all the rust from where the hub mounts. The hub should freely move around inside the knuckle. Anti-seize this thoroughly before reinstalling.
