What is this tube? (1 Viewer)

I spent a little time today rolling around under my rig looking at the diffs (4.88s) and LRA install. I see a disconnected hard tube above the front diff. Is this the OEM diff breather tube? I couldn’t really see where it ran but it goes up toward the engine bay.

My installer also installed an extended breather up on the engine bay so I think this is just the original vent tube.

Yep. Diff breather.

Agree with @bloc. I also bypassed mine with a flexible breather line when I did my lockers.
