in a week or so i`m gonna be changing the fluids in my front & rear diffs & t-case. i know how to do it all but i want to get you guys input on what is the best stuff to use. i`m not looking for the cheap way out looking to do it right.

 

in your diffs standard 80-90 works fine, in the t-case same stuff you put in your trany. Dexron/Mercon.

 

80/90wt GL-5 for axles and Dextron III for trans and transfercase. No specific brands just make sure they meet the spec GL-5 and Dextron III. Now engine oil is another story, I hate how some sludge up the innards I wouldn't spend extra on synthetics, it's better to use conventional and change more often especially if you run thru any rivers wheeling.

80w90 or 75w140 if youre towing
Dexron III for trans and Tcase

 

so no on the atf+4 in the t-case or the tranny. off topic where should i run my t-case and diff vents.
