    2015 Hellcat Challenger A8 In parking lots/low speed turns-not straight ahead-just when turning-read end noise-not a whine-not a rattle-sounds like a rubbing or lack of lube noise-not wheelwell rubbing on tires-dealer can't figure it out-said they called Chrysler-call not returned yet. I left message with SRT advisor..?any ideas? ?Suggestions?

    Others have experienced this. Take it back to the dealership ASAP.

    Tell dealer to add a bottle of limited slip diff additive (friction modifier) and test drive again.

    You may have a rear axle seal leak. You want it looked at. Look for fluid marks where the rear axles mate to the diff.

    Problem was fixed by dealer after the field engineer rode with me in a large parking lot doing slow figure 8s with the back seats folded down to better hear the rearend. He agreed it was the LSD. It took awhile to schedule but the rear end was silenced by inspection/drainage and refilling with lubricant-apparently just whatever Mopar puts in rearends. No noise @ all now. Quiet rear end is a happy rear end and owner. :)

    Have you had any more issues with your diff? Did they add the diff fluid plus the other 4 oz additive? I heard the current diff fluid already has the additive in it.

    Just had this happen too and they are replacing it on mine as well. I wonder if this is a common point of failure and they need to look into possible recalls.
