So I finally changed out my factory upper rear control arms on my 07 with 180k miles because the bushings were shot and I decided to put in Dobinson adjustable uppers with the factory style rubber bushings. Also changed out my stock panhard bar at the same time. So I set the upper links to +1/4" longer than stock to help improve the pinion angle as that seemed like a good thing to do. Not long after doing this I noticed a rotational clicking or clunking noise coming from the rear end.
I couldn't for the life of me see why changing the Rear UCA's would cause this so I looked at some other things. Pulled the rear diff and checked that thinking the ring gear might be chipped (because I've broken my rear diff before and it was a similar sound) and pulled the driveshaft and got that rebalanced. Everything looked pretty good and I put it back together and still the clunk. So I took the UCA's off and set them back to factory length and voila...the clunk is gone. I need to drive it some more to make sure it's still ok but does anyone have any insight into what might have happened there??
