When rebuilding a diff, what grease, if any, do you put on the outdrive shafts before inserting them into the diff? I've seen videos with people not putting any grease at all (example), some put silicone diff fluid (example) and others put black grease / lithium grease (example). Since it's a little exposed to dirt, would it make more sense to use dry (teflon) lube, candle wax or graphite?...
For the o-ring, it seems green slime is the best choice, but I've seen people put silicone grease and black grease as well. Won't that cause problems?
Is it a good idea to put a drop of silicone oil under and on top of the shims before putting the gears in? I don't see anyone doing this but I doubt heavy silicone oil would get to those places all by itself.
Finally, I think it's important to fully fill the diff with silicone oil, because mixing it with air would create a much lighter emulsion, right? Do you guys overfill it slightly and let the oil bleed out via the grub screw in the diff cup? Or is there a better method?
Maybe I'm overthinking it too much, but since it's quite a bit of work I prefer to get it right from the start
