... time to service the 12k Quality axles on the GN, what lube do you guys use? TIA!!

Lucas or amsoil full synthetic gear oil...waytogo waytogo

Weight?? See anything wrong with Mobil1 75-140?

your hub oils are basically the same as using any of the good gear oils, whatever your flavor will work.

Thats what I was thinking, so I used the Mobil synthetic stuff I had on hand.

I believe you'll be just fine.
