Maybe it would help if you told us why you're asking about gear oil. The way you asked the question almost makes it sound like you found a case of it that fell off a truck and said, "Hey, I wanna use this in my Jeep! I wonder how I'd do that!"

Exactly.

Yes - sort of. It's not bearings but rather the sychronizer hubs and rings.

API GL-5 is corrosive to brass. The AX-15 is full of it. GL-3/4-compatible fluid needs to be used.

Redline MT-90 (which is now stocked at all of the NAPAs in my town - yipeee!), Pennzoil Synchromesh, AC Delco Synchronized Transmission Fluid, etc are sane choices that won't kill our "obsolete" transmissions.
