    The rear end in my hell cat started groaning in slow turns. took it in last week and they said the fluid was burnt and the unit was gone. Replacing under warranty of course. Anyone else lost a rear diff?

    I found a thread that talked about the groaning from the rear end but that the dealer just replaced fluid I believe

    No change, I was just wondering if 2016 has rear differential issue such as 2015 had some issues.

    The only thing strange about the failure was it was at the dealership for new tires and alignment the week before. 50 miles later it started

    Make sure the rear tires are the same size. Maybe some one grabbed the wrong size.

    Very surprised they replaced the diff. The noise is the CF clutches rubbing together. Very common issue with these LS diffs. Both my Shelbys did it also. A little friction modifier and it was gone. Usually diff is worn when you hear loud whining. I had the whine on my first HC and they replaced the diff. Brand new diff growled but never had another problem.

    I'm not sure what type of Growling, whining or clunking noise are we speaking here.. But I'm hearing weird noise in the rear (It ain't wheel liner, DS rubbing or anything) .. I am going to put the camera in the rear and see if I can capture that dang noise..

    Mine was making a small amount of noise when making moderate to hard left turns, but the other day I was making a sweeping right turn and it sounded like the rearend was groaning (binding). When I took it to my dealer my service adviser told me they had just replaced the rearend on his Challenger and it was still making the noise. They are very interested to see if mine will continue to make the noise. They believe that the one they got for my service adviser might be bad and are curious what mine will be afterwards. When I asked them what they thought it was they said Chyrsler was not sure but have been documenting many of the same issues and were just going to replace.
