If this was true, then we wouldn't need a shift motor on the transfer case...which often locks up if much time has passed without engaging 4wd. Good idea to shift into 4wd a few times a year just to keep things well lubed.

I'll let you know after I pick up the truck and ask questions.
You won't be able to "see" the hub as it's all contained within the wheel assembly. What you're thinking of are "manual locking hubs" that many rigs still use where you in fact exit the truck, turn a selector on each wheel, and get back in the truck. The hubs in our own trucks are auto-engaging...thus the vacuum pressure. FWIW the vacuum lines are small, black, flexible pvc and should be coming out of the top near the location of where the half shaft enters the wheel assembly.
You really should read the link I provided. It's VERY helpful.
