If you use the hammer and punch, I would make sure that you lube it up with nut and bolt penetrent a few days before you do it. Mine was not easy to get out with the proper tools.
I think the only line that I had to remove the vent line. Its been a few months since I broke it, so I'm kinda hazy on the process. I had the bike on jack stands, and the axle on a floor jack. When I took the bolts loose, I had a buddy pull the swing arm away from the bike just enough to get to the joint. The brake lines were still hooked up. I replaced the joint and put it back together. Be careful, one the swingarm bearings fell out on me and I ran the swingarm bolt all the way in before I realized something was wrong. I took the whole thing back apart because I couldn't figure out why I had slack in it. Then I found the bearing under the floor jack. Hope this helps.
