Best Differential, 5-speed and Transfer Lubricants?
I would like to get a cross section of what's being used for drivetrain lubricants.
Please indicate what you are using and for how long. Any issues or regrets? Tell it all! Thanks...

Brand is not as important as the correct lubricant rating / viscosity.
Here's the specs for you:
Front Differential: 75w-90 GL-5 synthetic gear lube
Rear differential: 80w-140 GL-5 synthetic gear lube
Transfer Case: Dex/Merc Multi-Vehicle ATF (Dex/Merc III is the spec fluid - whatever fluid you get must be compatible).
AX-15 5-speed: 75W-90 GL-4 Gear Lube. This is very important for the AX-15 due to the brass syncros - GL-5 gear oil will eat them up. Two very good choices are Redline MT-90 and AMSOIL MTG.
