Rep Power: 268

okok, so i lowered my car for about a few months now on stechs and blues and everything seems to be fine, then one day when i was making a wide left turn on the freeway a *crr crr* noise came off the right back side of the suspension. i think it might be because i didnt tighten the hex nut and strut all he way because i can still turn it a bit at the top, but what do you guys think it is? the noise is really irritating me now >_< and btw, how much did you guys tighten the hex nut?
