i had my shocks COMPLETELY BLOWN, leaking like crazy, and my tires had the metal coming out even =) and let me say, if u have blown shocks, u should kno, or can tell. my car blew in like 3 months, being lowered 4 inches, with OEM shocks. and my car was bouncing and it felt like my car was about to come off its wheel ... not a very good feeling. even tho my ride was bouncy even from the beginning, i could tell when they were blown. i dont kno, if its so much of a sound, only thing i could tell was when i hit the bumps, perhaps they got louder. one question guys, when my shocks were blown tho, and my mechanic took it out, when i pushed the ACTUAL shock, its rebound speed was very slow. i pushed down on it, and it came back up like a snail. not to mention, it was very dirty. while the one that was new, rebounded fairly faster. ???
