    Wow! There must have been a full moon when I went through the same thing. First I checked backlash. Was at. 012 so I tightened it to. 008. No difference. Replaced the spider gears and cross shaft. No difference. Looked closer and found the poly bushing on the upper arm was shot. I had boxed the uppers and installed poly bushing which I know now that doesn't work on a street car. Removed the plates I used to box the uppers and replaced the bushings. Still clunking.....WTF. I'm now at my wits end. Grabed the driveshaft and gave it a twist. Seemed a lot more than. 008. Pulled the cover AGAIN! Everything looked fine. Checked backlash again and it was all over the board at different spots. Looked closer. Found the problem. Friggin ring gear bolts were finger tight! Years ago when I didn't trust myself to do a gear change, I had a reputable shop do it. Lesson learned.

    I had a known rear end shop do mine, but sounds like I'm going to be taking the cover off and checking it out myself. I've heard off shops not having things properly tightened or torqued... I guess that's what I'm checking next. Thanks for the help! I'll let you know if it works out.

    If they didn't put fresh lock tight on the ring gear bolts they may have come loose. Usually doesn't happen but sometimes small things like that get over looked in high volume shops just something to look at.

    Nothing I can tell that is wrong with the rear end itself, I'm thinking it has to be bushings or suspension, something along those lines. It'll be a while before I can figure that stuff out, this winter at some point. Thanks for all the help

    What did the 8.8 come out of? Does it have disc brakes?

    Check you brakes and make sure you assembled them correctly ie the caliper not moving and clunking around. Did the shop put new axle bearings in? These would be the ones in the outer axle tube not the ones holding the carrier in the rear end.
