Hate to bump this.
New axle from a '10+ car.
V237-R on the main axle tube sticker/decal.
Barcode on the diff cover reads:
Also have a number series. The Alpha-numeric pair is on "top" with the character "below".
D14/Y, E46/A, E28/B, E12/B, E64/A, D15/Q
Any help as to what this assembly was originally would be appreciated.
It now contains a 3.73 gear set, which should be OEM, trying to verify it's origins.
