My indie showed me the bushing compressor he used to do mine. It's a tapered socket the bushing is pulled into with a bolt and washer much like the way a gear or pulley puller would work. He said the front position bushings in the swing arm were the toughest to do and the swing arm would definitely be damaged it you tried to let it compress the bushing as it was driven in. I noticed that Summit Racing sells bushing installation sleeves that might be usefull.
