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.

 

[challyjim]

No more issues. The dealer paperwork indicated qty 2 lubricant 01081090 (68232948-AA)and qty 1 lubricant 01081033 (4318060-AC) (lubricant; additive) Covered under warranty.

Just started having this issue a couple weeks ago, took it in. Rear diff fluid burnt, replacing!

 

[PhantomWorks]

just took mine in for the same issue. They are replacing the rear end.

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.

I had my rear making some strange noises once or twice after drag racing at the track. But then next time I drove it I did not notice it and all seems well now. Maybe it does not like it when I am doing my burnout and there is water under one tire but not the other tire, or something. SO, for the most part it is good.......

They replaced mine and it is worse! I have already discussed with them and will be taking it back for another when I have time

Guys I've been through this. Dealers treat this issue in different ways..some change out the fluid, others replace the diff (like my last car)

Bottom line you can replace the diff 10 times and THEY WILL STILL GROAN. It's the nature of the beast! Save yourself a lot of time and aggravation...let it go.

Not talking about normal groaning. I've had my car well over a year and 28k miles on it. I know the normal sounds and feel. Hopefully the replacement will fix it.

For serious issues absolutely take it in. I was speaking specifically to OP's initial post.
