I run Valvoline 75/140 in the rear with the friction modifier in it already, and 80/90 in the front. Have for a few years that I’ve had the Jeep. No issues as of yet.

The manual specifies 75W140 for the front diff, 75W90 for the rear, unless you tow a lot, in which case use 75W140 as well.

2005 here ... I run 80W-90 Dino in the front axle. I run 75W-140 Syn in the rear axle - for no other reason than mine had the factory "tow package".

I rarely tow anything, but the manuals are ambiguous. It says 75W-90 Dino if you don't tow - but what if you happen to tow "once"?? So, what the heck, I just went with the 75W-140 Syn.

I don't tow at all, but recently put 75W140 in both diffs, it's just easier buying one type of oil.
