yellowknife, I don't get a thumping sound anymore (that turned out to be my control arm). Its just a scrape sound that I don't get all the time. I run over bumps, speed bumps, railroad tracks, etc and I don't get it throughout the day. I've only heard it twice: both times I was leaving early in the morning when it was cold and hitting that dip straight on.
