80w90 valvoline w/ limited slip stuff in both ends on mine. Dunno though, NBS trucks want synthetic in the rear (but not the front? :think:). I think I bought 4 quarts last time and it was enough for both diffs. For some reason the computer at carquest gave me the capacities in pints, and I couldn't remember what a pint was...yeaaah.
