Pweber, I'm in the process of doing mine as we speak. (Take a look at my other post today.) I have the special tool, which works well to remove the front bushing and looks like it will work to press in the new ones, but I'll guaran-goddam-tee you it will not work to get the rear bushings off. Neither will hammering. (I've tried with a 20-lb sledge.) To get the rear bushings out, you'll need to take the LCAs to a machine shop to press them out. You may want to do that, as you're halfway there (you have the LCAs off the car). The machine shop may also be able to press out the front bushing and press in both front and rear without the special tool. But if you want to use the special tool and not buy it, I'll rent you mine when I'm done, which should be tomorrow.

softconsult is right, the new bushings have a specified orientation--basically, the obvious marks go perpendicular to the plane of the LCA.
