Don't attempt it If you don't have a press and the proper tools to remove and install your current ball joint. I tried to do it with couple of sockets and a vise one time and I messed up the seal. Doo sells special tools, but it's probably not worth it unless you plan on wrecking more a-arms. I would take the old one to your dealer when you go to pick up the replacement parts and have them install it for you. Also, if this happened while you were on a carve, you probably cracked your S-module.
