This is definitely doable. You can do it with the ball joint press from Autozone, and you don't have to take the whole swing arm off either. You do need to take off the rotor, and pull the strut towards the rear a bit. I tied a piece of rope to the rear door handle to hold it back. You also have to be able to lift the van up enough to get the press in to position.
Pickle fork type separator and prying to get it apart. On the factory ball I had to cut away the rubber boot to get to the retaining ring, but it's there. Get under it with a screwdriver, or chisel and hammer (not hard, just easy), then pry it off. The inner CV popped out on me also. Just line it up and tap it back in. If this happens you start leaking ATF, so check the level afterward.
