Weird Squeking noise when reversing and sharp turning at low speeds

[Hemi1284]

Good day , My 2023 charger hellcat makes this weird squeaking noise when in reverse also when making hard turns and low speeds. The car only has 6000 miles, did some research some say it may be faulty diff or diff fluid, or drive train issue, but I’m not sure where to start. Was wondering if anyone had a fix or an idea, any help will be greatly appreciated.

if the "squeak" is more of a groan from the rear during low-speed turns, change the diff fluid, and add 4 oz of friction modifier with the new oil, or just go with the higher viscosity gear lube used in the viper (will lower gas mileage a tiny bit). either one should quiet it down [did the first early on for my '15 HC, stayed quiet for about 15000, recently switched to the heavier weight, all quiet once again].. there was a TSB for the 2015's, but can't find it at the moment
if the "squeak" is more of a scrapping sound, I'd suspect the front breaks. pull the wheels off, verify the rotors are properly mounted (left front on my '18 was incorrectly torqued, was a bit loose), give everything a thorough cleaning

Maybe the squeek is just stiff suspension bushing from not being driven and stored? My mustang used to do that after I changed all the control arms and bushings...
