You do not have automatic hubs. The only disconnect is the transfer
case itself. When you flip the switch, it activates a motor which does
what the lever on the NV231 did - engage the front driveshaft. When
you're rolling down the road, your front axles, diff and driveshaft are
all spinning.

I made a lot of noise about the electronic 4WD knob when it came out in
'01, and I still would prefer to have the positive engagement I felt w/
my lever-operated 231 in my '99, but damn if the electronic ain't a hell
of a lot safer and more convenient.
