i have brand new 2019 hellcat redeye with hollowing noise in rear since day one. brought to dealer this week and they agreed noise not good.they ordered new rear from factory and notify me when it comes in its the 309 rear.sucks
Sorry to hear, many challenger owners including myself have noisy rear differentials in my case in 5th gear at 45mph at light throttle the rear make a whine noise. It’s not super load and obnoxious yet but then again I don’t have many miles on my 2019 yet either. So I am monitoring the noise and will advise my dealer long before my warranty runs out. Seems to be an ongoing annoyance with many challengers.
Be interested to hear if yours noise is all the time or under certain conditions?
I got lucky, the Redeye has a good 3.09 in it, they are not designed and built bad, careful break-in followed for it (the engine don’t care, the first 0-300 miles are for the gears), and it is reasonably quiet for this kind of auto. My ‘15 HC whined because I did not follow the speed recommendations for the first few 100 miles, had to get a new differential to make it quiet down.
