[Linda's Hell Cat]

This has been a common problem with many hellcats and I wanted to know if anyone has a solid solution. When the car is at 45 mph or 65 it sounds like a minor whine coming from the rear end. I give the car very little throttle and it will start to make the noise. The car has made the noise since new and I now have 6400 miles on it. I've ignored it but It is now a little worrying to me. And yes, I did break the car in correctly according to the service manual. Anyone have confirm fixes that I should try? I've heard people doing a fluid change with a friction modifier, and people going under warranty to get a new pumpkin. Thanks!

I had not had the rear end whine but I can tell you one sure way to get rid of it.

Don't use a @Per4Mance Development Diff brace launch really hard and break the Pumpkin!

There are lots of thread about this and I won't say it's a common problem but there is a good percentage of those that had the problem.

I hope you get it fixed!

Sometimes when reading these thread on rear end whines I wonder about them and think why I don't hear anything I would complain about.
The Hellcats came off the line more of a race car.Race cars make noise. ?
Maybe I just don't have the problem with my Hellcat or maybe it's because I also drive a 3500 Ram Diesel Dually and anything is more quiet than that.

@Rockster I understand your thoughts. This is especially true.

"over time I've become more familiar with the car and the noise it makes and really while I hear the supercharger at lower speeds, and some diff whine at intermediate speeds, and will probably once again as the "new" tires wear hear tire noise at higher speeds I will know the source of the noise and not really give it much thought."
