Charger Making Weird Noise

[DZEKI]

Hey guys! So I recently bought a 2015 Charger SXT RWD auto. I've been driving in for the past 4 months and she been great.. but over the past couple of weeks I have noticed a strange sound. I seems to be coming from the rear end of the car. It sounds like when you drive onto the shoulder of the road over the road. Kinda buzzing humming sound. Anyways it happens after I accelerate then let off of the gas completely. Just one noise. "Vvmmm" one second long.  The noise happens also if I'm on cruise control. It seems to be something with the throttle position because cruise control can hold the noise for multiple seconds at a certain rpm. Ex. "Vvvmmmmmmmmmmmmmmmmmmm".  It's a repeating sound that I can replicate. It doesn't sound like the cars falling apart but it is worrying. I've had virtually all regular maintenance done in the past month or so. (Everything except a differential service) <Might be a good place to start.    The car has 77500km so she's still on warranty and I will be bringing her into the shop shortly. Just looking to see if anyone has had anything similar happen! Thanks  Dzeki

I'd be looking at the differential

Some on here have modern chargers and will likely respond.  My input would be useless for modern charger, otherwise I would give my  .  Good luck sorting this out.

Stop texting and stay away from the rumble strips in the shoulders of the road,

This forum is geared to 1st through 3rd gen Chargers, i.e. 1966 to 1974 Chargers.  You might have better luck here:  http://www.lxforums.com/board/

Some people THINK that they have a sense of humor but the only ones that they amuse ....is themselves.
I found the above funny....The OP ? Not so much.
