Have you added the mopar friction modifyer? You do need it with a Limited slip. If you didn't add the modifyer it will pop and snap on turns.

Did the rearend guy soak the new clutchs in the stinky stuff ? What kind of gear lube are you using? Try Red Line 80-140 & Red Line friction modifier.

a while back I was getting a lot of grabbing from the LSD during turns, put in 4 oz. of the Chrylser friction modifier, from the dealer I think it was $ 5. 00 took care of the problem, it was probably 2 or 3 days of normal driving before I noticed the all the grabbing was gone, maybe I should have started with 2 oz? but in reading threads regarding this some people seem to have much better performance with Chrysler vs. brand X, also noted some people had to put in significantly more than the 4 oz. I put in, I would add 2 oz. at a time untill it goes away, some suggested driving figure 8's after putting in the fluid to work it in.....

The figure eights and or circles in a parking lot is recomended with all clutch type LSD diffs. usually noise goes away in a few minutes.
