Does your AC work? Its either the 4x4 line going to the solenoid next to the battery or the vacuum reservoir behind the battery, or it is the vacuum line to the AC.

Is it going down the same wire loom as the line that is connected next to it? If so, Its the vent for the hum actuators. See if you have another one just like it on the drivers side.

Yes out of the same loom as 4wd solenoid tube. That's why is probably turned down as a vent.

I do not see one on left\drive side.

Ok, that would be my second guess. There's one open vent line on each side for the front 4wd hubs. There's not that many vacuum lines in this truck.
