Default huge discovery = no more clunk

For the past two years my car would make a horrible clunking noise when going over speed bumps or during jerky acceleration. I have the dealorship check it out everytime I go in and they could never find anything wrong. I always thought it was my scoobysport exhaust hitting the rear diff, but that wasn't it. The two nuts above the rear diff turned out to be loose causing the rear diff and the parts in that area to bounce up and down. I tightened them, now it's completely silent!! I'm so happy. I think I have to replace those rubber bushings in that area now cause all the bouncing has damaged them.

I hate when bolts loosen up like that. I know a friend who had an axle come out on him cause bolts loosened up. Now that sucked.

what do those bolts hold? Do they actually hold the dif in place? Nice find it's like me trying to track down all the noises after my TBE install. I thought I had found it when I found that one of the bolts on the middle joint was loose, but that wasn't it. Then I ripped one side of the heat shield off the cat. That stopped it for a while, but now I guess I need to take the other side off. What a PITA!
