I think I need to change my gears, anyone know what my diffs would currently have? I assume 4.10 but doesn't seem like it.
thanks in advance cause I know someone knows the answer!

Pull the back cover off the rear diff and take a look-see........

You'll know for sure then......... removes the guess work...........
