Greetings:

I am going to put Valvoline Durablend 80w-90 in my front differential, and Mobil 1 75w-90 in my rear differential. Why does it called for the heavier weight in the front, and slightly lighter oil for the front axle? I have The squared hex fill/refill plug bolts on the passenger`s side of the rear diff. Does anyone know what the actually size tool/socket, that one must use. And what size is the front axle bolts? Also what is the capacity of both diffs. Thanks in advance!

Best Regards
