Tried finding this without asking, but found conflicting info.

Does a '16 Pro4X CC with AT need the vent mod?

Done.
And glad I did it.
I dis-assembled the factory vent cap to see what Nissan engineers were thinking. Spring-loaded flat Teflon disc held inside the stamped housing.
So it remains in a "closed position" (disc face rests on nipple end) unless/until enough pressure builds inside differential to compress the spring "open", and then only until the pressure relieved equals spring tension.

Crude to say the least.

Certainly not a superior design for a road grime environment, much less a submerged axle.
