On the freeway today from the dealership, I heard my passenger rear tire rub against the fender for the first time. I got off the off ramp and checked my tire and suspension components and everything seemed fine. I drove it again and heard a loud bang and now everytime I go over bumps I hear something loose on that side of the car. It also makes a bed creaking noise when I brake semi hard to a stop. My suspension setup includes the HKS LS coilovers, hotchkis sways, kinetix rear camber and toe arms. I haven't checked the bolts out yet since I'm at work, but this really pisses me off. How long do coilover shocks last?
