75-140 is what Nissan uses now. It is the proper fluid.
Axle clunk after fluid change...
Drained the old foamy mud out of the axle last week and refilled with Mobil 1 75-140 weight and yesterday noticed mild clunk at low speed when it shifts from 1st to 2nd. Is the 140 too heavy? Should I switch it out for 75-90?

They changed the weight starting in '05. If you have any damage, it was probably from the old fluid.
Thanks for the feedback guys. This morning I listened carefully as I started out onto the street from my driveway and the sound is more like a clang (bell sound) than a clunk. I'll double check the fluid level tomorrow. I have a bunch of drivetrain warranty left so if there is any permanent damage due to the wrong fluid, I am covered.
If you have any weird noises, get it fixed or replaced. There haven't been many rear failures in the Armadas. The titans have had the problems, but there is no 100% rear on the market and there will always be one or two that aren't right from the factory. Good Luck!Sand_Warrior said:Thanks for the feedback guys.

Yup! Gotta make an appointment for this and the final brake fix too. Thanks Trip! 
My 05 manual recommends to use "API GL-5 Viscosity SAE 80W-90". Not sure what is the recommendation in 06 manuals. I have been using 75-140 weight for some time now. Make sure you have the official recommended weight before you go to the dealer so they dont blame it on the fluid and deny you warranty coverage.92TripleBlack said:They changed the weight starting in '05.

I used 85W-140 (closest I could find locally).
I doubt it's the fluid if you're getting bell clangs and knocks. I'd recommend taking it in for the noises.
