I just read this article http://www.quickorsuspension.com/articles/polybush.htm about poly bushings, and would like someone with first-hand knowledge to comment. Did you use graphite-impregnated bushings? Have you used them long enough to know if they last? If you use standard poly bushings, what kind of grease did you use and do you have zerk fittings. Ultimately, did they last and do they squeek? It wasn't to confusing to me until I found this article, but you never know if it's BS or not. Thanks all!
