Comedy gold, here.
I think that since we're on an automotive type of forum, that when we use the word "turn", especially in context with an object or objects, that, well, generally rotate, or "turn", if you will, that saying that a rotating part does NOT turn when directly activated and mechanically linked to the rest of the driveline as opposed to turning ONLY when said activation and mechanical (or fluid-type) linkage (in 4A) in this exact instance is both wrong and misleading.
Now, I've been around 4x4 vehicles, mostly Ford and Jeep since I got my "road ticket" over 3 decades ago and have worked on, in, and under every single one of them (I did say jeep, did I not? LOL!), and regardless of t-case type, method of transferring power to the front, via chain, fluid viscosity change, or simple gears, if the vehicle is in motion, the system is in proper working order, and the selector is engaged to activate the t-case and the front driveline, then the axles and ring gear HAVE to rotate.
I have tested this myself on my own '11 Expedition trying to track down a noise. Tires (4) off the ground. In 4H, in drive, idling....guess what? front and rear both turned.
barring broken parts, this can't NOT occur.
