Have been hearing a clunking in the front of my silverado 2wd. Thought the coil spring isolators were worn, after looking under there, my lower a arm bolts were loose. I could unscrew the nuts with my hands. So I beat the [censored] out of them with the impact, now much quieter. But, Still hear the clunk as before, Sometimes? Its so anoying! Anyone else have/solved this problem,? THanks
