Differential Question

[bamato]

I want to change my gear lube to a H/D synthetic (Amsoil) Everywhere I look says to use 4 oz. of Mopar Friction Modifier if you have limited slip diffs. I have a Rubicon. Do you use the friction modifier with lockers?

I don't think you would use the friction modifier because you don't have clutch packs like in a limited slip. You have a mechanically locking air locker.
