Check the Autozone tool rentals, there's a tool used for pressing ball joints that's basically a cup set in a C clamp on the opposite side of the threaded press. Sometimes the cups are large enough to press bushings, and some Autozone stores have presses especially for bushings available. If you know any electricians, a knockout punch set (drag outs) can be used for removing and installing bushings if you're clever and have some threaded rod, long bolts, nuts, etc to work with also.
Definately find the tools, and familiarize yourself with what you'll have to do first [thumb]
