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!

Have the driveshaft inspected, specifically the carrier bearing.
If the carrier bearing is good, then have a service manager conduct a ride-along to hear the sound you are experiencing between 45-60mph. They can then look into replacing the rear differential and fluid under warranty.

Two options are to have the differential inspected for warranty. They see if it needs to be replaced or changed with new lube and friction modifier.
