I want to replace all of the drive train oils (just bought her). I have a manual on order but in the meantime am having some trouble finding the info on the net. Could someone direct me to a site or list all of the factory recommended oils for an 1983 4x4 for the engine, trans, t case and diffs.

 

Straight out of my '85 Owner's Manual:
- http://www.4crawler.com/4x4/4R_TechInfo.shtml#Fluids

 

From my owners manual it says, 80w-90 for transfercase, differential above 0 degrees sae 90, below 0 degrees F 80W-90, Brake fluid dot 3, Power steering-atf dextron or dextron 2. Motor oil depending on weather, 10-30 10-40 10-50 from 10 below zero to 100 degrees. I live in a cold/warm climate and run 10-30 year around.
I also use synthetic for my 83. <B>
