Just noticed a creaking noise coming from driver side during low speeds and it gets really loud when going over speed bumps. I can't tell if it's the front or rear. I'm guessing it has to do with the suspension? I did get UP coilovers installed a few months ago but I'm not sure if that's the cause. I'm hesitant to take it to a service center. I assume they'll just blame it on the coilovers. Anyone experience anything similar?
