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!

Change the rear end oil..
My Demon was 5oz low when I changed mine at 700 miles.
I used Amzoil Severe Gear with Slip Lock. I just seen last week a 2018 Hellcat that was also low 4oz upon inspection and fluid change.
