Rear differential oil - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What weight does it call for? What about capacity? Is one of the typical cone shaped bottles enough for a drain and fill, or does it need more?

I'm probably going to go with Mobil1 full synthetic

I've done this on other vehicles before, but not this truck. Do I just remove the top plug, remove the bottom, let all fluid drain, then install bottom plug, and fill through the top until fluid starts to drip out the top hole, then plug?
