I just installed an ARB in my 8.25 & aYukon air locker in my D30. I was wondering what fluid are you guys runnin with air lockers. I see ARB stated to NOT use ones that state "For Limited-Slip Diffs" and "Friction Modifiers"

I also regeared at the same time do I have to do the breakin's for my R&P.

Let me know what you're using & why. Synthetic good/bad, one brand over another.

Thanks in advance.
