I had to do those bushings on my '94 E36 and they were no easy task. I had never done them before but I got a tip from the mechanic at the BMW dealership to use the gear puller. (I had to get my alignment done and I had to replace the bushings before they would do it. They thought they were going to make $385, it costs me $80? I forget. That or less.) Definitely a good idea. Just rent one. Pay for one? lol screw that, I'm in college. Anyway, the gear puller should get them off without too much hassle. I actually ended up using a torch and melting some of the rubber off and then the outside bracket came off, then I used the gear puller again to get the center bushing off the arm. As far as putting them back on, I mainly used a 3lb hammer. Get the new bushing and bracket started with a few taps, then take the old center bushing and put that in front of the new bracket and wail on the old bushing which will act like a damper. Your arms WILL get tired. Get over it and keep wailing until they're all the way on lol. If it makes you feel any better, I put the first one on backwards! So I had to then pull it off and do it again. Not fun, make sure you don't do the same. Good luck.
