Inspect this oring. Take the locking hub off, clean, inspect, R&R oring if necessary, lubricate and put back together.
Then try your Hub & A/C.
If your not 4 wheeling put the hubs in the auto position(free).

What other things would you check?

I hooked a vacuum pump to the line going into the hubs, both hubs held a vacuum...where do I check next?

I don't mean to split hairs but what they have is suction; vacuum is created when suction draws against restriction.
Since it sounds like you have access to a hand vacuum pump I would check the system from the solenoid (on the right fender well near the battery) down to the hubs. There is a molded rubber connector with 2 plastic lines, one is vacuum supply from the black plastic reservoir tank and the other goes to the hubs. If it does not hold vacuum then track the leak. If it holds vacuum then I'd suspect the solenoid. Just to be sure plug the side of the rubber connector that goes to the vacuum reservoir, see if the ventilation works (it probably will since it works in 2wd). Then reconnect the solenoid to vacuum and plug the side that goes to the hubs (you may have to rig some connectors and vacuum hose to do this), set the transfer case to 4wd and see if the ventilation system still works.
As an option you could convert to Dyna-Trak hubs and have servicable bearings and real manual hubs (and probably get your wife p-o'ed at the money you spent).

I'll give that a try.

Fixed! Was a leak at the solenoid.
