I use 75W90 GL4 for the gearbox and transfer case
80W90 GL5 for the front and rear diffs, think I also have used EP90 as well......dont think it makes a differance.
I must say that since I started using 75W90 for the gearbox, my gear shifts have been allot better, specially when its cold in the morning. It is also a full synthetic one, but thats only because its the only one I could find.....they are very scarse
But on the gearbox noise at low rpm and idle there was no change
