does the front axle turn all the time on my 4x4

I just found out the same thing...my '03 Durango front axle assembly turns all the mechanicals all of the time up to the transfer case....no wonder it only gets 14mpg pushing all of that mass. I had a '93 Bronco that had automatic locking hubs when the 4 by 4 was engaged. Who da thunk that a vehicle that was 10 years newer would not have had the same thing or better?

the reason that they dont have auto locking hubs on there is because with those hubs the entire front drivetrain is sitting dry most of the time, and this causes problems with it when it only gets used on occasion, this way with the front drivetrain always turning it stays properly lubricated, and it really is not that much of a load for the truck to push, and it makes it much easier to keep up on the maintance, with the auto lockin ghubs you need to run the truck in 4x4 on a regular basis (weekly or monthly) in order to keep up the lubrication, you do not need to do that with your durango bc everything keeps turning and therefore stays lubricated

Sharps is totally correct.
This differential is a Open gearing diff and not a Locked diff so it has spider gears. This allows the wheels to spin at different revolutions. Also the drive shaft is disconnected from the rear drive shaft in the transfer case thus it can spin at different revolutions than the rear.
When you want 4X4 you engage the transfer case and then they are locked together.
