Nearly any GL-5 or GL-6 gear lube is fine and personally, I use and recommend a NON-synthetic gear lube for the axles as it seems to help them run a little cooler than a synthetic does.

And if your rear axle has a Tracloc limited slip differential, you just need to make sure the back of the bottle says something like "compatible with limited slip differentials" as most of them are. 70W-80, 75W-90 etc. is fine for cooler area, 80W-120, 85W-140 etc. is fine for towing, and/or warmer climates. The axles are not especially fussy about the exact viscosity gear lube they get. You'll need two quarts but it doesn't quite hold all two quarts, something like 1.8 so you'll have a little left over. If you don't have a Tracloc, you can still use that type of gear lube as it is compatible with non-Tracloc equipped axles too.

Regarding sealing the differential cover back to the housing goes, Permatek Ultra Black RTV (like silicone) works fine and is leak free if you don't overtighten the bolts so much that too much of the RTV squeezes out. Instructions for its use are on the tube and pretty much any auto parts store should carry it.

Remember that having a different opinion doesn't also require one to be a jerk when expressing it.

When you have a choice, buy American.

X2 on Jerrys comments, but I would recommend getting the Lube Locker gaskets for the front & rear. Makes things easier for future fluid changes and I've had mine for almost 1 1/2yrs now and they are great since they are reuseable. Just make sure to torque to the right specs listed on the the sheet if you buy them.
