I was needing some information on what you think is wrong. I have a 2008 half ton silverado. I installed rancho 9000XL shocks on the rear about 6 months ago. Recently I started to hear a clunking/popping noise in the rear end when I go through dips. I can really tell when I pull into my driveway, while turning through a dip. I can go slow or fast and it still pops. I just got it back from the dealer and whatever they did was no help. It would be great if someone can help pinpoint the problem. I have already checked the shock mounts and they seem fine.
