If u lowered ur car than try driving the hell out of it around turns and see if that helps. It hleped with my car. At first it was clunking at the front. I got so pissed that I just tore it up around corners hoping secretely that whatever is making that noise would brake so I could see what it was. Soon enough the noise stopped. A few weeks later I pulled the e-brake and slid around a 90deg turn and the noise came back, That day i had to drive 3hrs on the highway and when I got off it stopped. Nothing since than and it has been a while. I heard its something to do with the srings settling in. Also mine cluncked on turns as well as bumps.
