The green light on the gauge cluster does go off when I put it back on 2H. So does that mean that the hub is functioning correctly?
What exactly controls the light on the cluster? Is it the transfer case? the front axle? Is it possible that it is getting "wrong information"? In other words, how reliable is the light on/off status as an indication of whether or not the 4x4 is working and engaged (or disengaged)?

And thank you for that diagram, very helpful. I will take a look at the wheel today when I get the truck back, and see how it compares.
