I haven't seen much talk about this in regard SAAB bushings, but this comes up all the time on the BMW tech talk groups and fora. The idea is to get something that will lube the bushing for installation and then go away, and also not degrade the bushings themselves over time. A few commonly mentioned items are hairspray (have to work very fast) or liquid soap or detergent such as dishwashing liquid. I have also used spray silicone with good success. -- -Fred W
