Gear oil suggestion

I have a 2000 XJ and im running 4.10's and ARB air lockers in both of my axles. Both axles are the stock D30 and 8.25. I couldnt remember if I need to put something different other than the OEM recommended fluids since I have the ARM lockers. Any suggestions what to throw into the diffs?

I dont live in a very cold climate so I done have to worry too much about snow and ice issues.

No special requirements just follow your owners manual.

Ok, which gear oil is best? I have seen people using 75/140 and others something a little different. Also, do I need to add a friction modifier since it is limited slip once the lockers are shut off?

Um...its not a limited slip when the lockers are off, so, no, no friction modifier needed....

Ya ARB's are not limited slip when off. 75/140 works well, less noise from the 8.25.
