Which is it? Front and rear diffs mean a four wheel drive, yet later you say it's a 2wd. Either way, it depends on what you use the truck for. 75 90is good for the front axle andthat would be as light as I would go in the rear; only if you don't tow or haul anything heavy. 75 140 in the back if you tow/haul frequently. Or somewhere in the middle, again it depends on how and where you use your truck.

the NV4500 takes 8.5 pints of 75-90 syntorque.
if you tow alot I would suggest going with either a 75-110 for moderate towing, or 75-140 if you tow heavy. just make sure you add about 8oz of friction modifyer before adding fluid if you have a limited slip rear. and you'll ne a bit over a gallon of fluid.

RE: what kind of differential fluid??
I dont think I labeled things properly for ya looking back on my post. . .the tranny needs the 75-90 syntorque, and axels need 75-90, 110, or 140 with the friction modifyer if you have a limited slip.
