what kinda bushings do you prefer? i am very unimpressed with the performance of the new bushings that came with my tuff country springs. i guess they are polyeurathane? i put a bunch of poly grease in them twice, and they squeak very badly, and they seem to be tight. i know poly lasts longer, but quite frankly, i don't care. if i have to change my bushings out every couple of years, no big deal. i'd rather them be softer, and not squeak. i know they have greaseable bolts, but, i do not have room because of the very tight fit between my shackle and dynomax header collectors. are there rubber or graphite or some other kind of bushing that works well, and is relativily inexpensive??? i dont really care weather they last 2 years or 10 years, i just want something that doesn't squeak, performs well, and doesnt cost a whole lot. wheres a good place to get bushings cheaply?
