You should be able to tell from the codes on the door jamb sticker or the label on the differential.
3.73 is an available option from the factory and fairly common, I'm pretty sure 4.10 is not an option from the factory and not very common.
It's real risky to diagnose a sound from a description over the internet . . . . but it "sounds" like it might be the typical 3.73 gear whine. If it is still under warranty it is worth a shot to take it back to the dealer and see what they say. But usually they say they can't hear it, or it's "normal."
