Noise from Limited Slip Diff?

[ecodiesel2020]

I'm hearing low level humming noise from the back of my 2020 jeep JL with eco diesel. I'm suspecting it's the limited slip that's going out, the noise occurs in drive or reverse and occurs when turning left or right, it seems louder turning to the left. Does this seem like a Diff problem or something else.

Lift both wheels and check if they spin in the same direction.
But are you sure you got a LSD in the first place?

LSDs require special oil and/or additives to operate properly and quietly.

Yes - definitely LSD

Think it might be a wheel bearing?
