2023 Off Road humming sound

My dad's 12K Off road has humming sound in rear differential, as if it was low on transmission fluid.. But we got truck brand new and now its at 12K.

I was wondering if anyone have had any issues like this? we went to dealership, they drove it and said its fenders or some bs. They won't check the fluid even if we asked them to.

 

Search function is your friend! Probably a couple hundred pages regarding this issue.

Known noise issue with the rear differential.

 

let us know if the sound gets resolved either sooner or later or not

 

What others said. Rear diff suppose to be gear oil, not transmission fluid. Dealer must be lazy, not want to check gear oil in rearend. Go to another dealer, or check it your self.

 

Thanks, ill follow up there

 

My truck hums to Eagles songs.
