My damn R/R of my car is making a rattling noise...its been there since i installed my springs, and it doesnt sound like its coming from the actual spring/strut assembly, but rather around the seatbelt mechanism...its not that loud, but it pisses me off...does anyone else have this problem, and if so what did you do to fix it? i already took off the seatbelt assembly, and put it back on and tightened the bolts hard as hell.
