So with IWE disconnected and in 2WD, wheels rotate, front axles do not. But with IWE engaged and in 2WD, axles must rotate with wheels, right? The axles are connected to the front drive shaft thru the front differential. So all that rotates also. No power is transferred because 2WD but everything turns just the same.
As the transfer case accepts input from the transmission, and the Hi-Lo range selector is in the “Hi” position, the transfer case uses the highest gear ratio. This ratio is usually near or exactly a 1:1 ratio. (same input and output speed of the transfer case, i.e. no speed reduction or torque multiplication). If the driver chooses the “2WD Mode” of the transfer case, power is transferred to only the rear wheels, leaving the front driveshaft without any driving duties.
If the driver selects the 4-Hi mode, the front driveshaft is engaged inside the transfer case and power is now transferred to both the rear and the front driveshaft, allowing the front and rear wheels to pull the vehicle.
When the driver selects the 4-Lo mode, the second gear ratio is used and power is directed to both the rear and front axle. The lower gear ratio is used when a multiplication of torque is required for steeper hills or where more engine power must be used to pull the vehicle.

That's what will happen if you install the RCV IWE Eliminators and also if you don't have vacuum to the stock IWEs.

Ford released a TSB for this. The inner wheel ends break, causing a leak in the system. The noise will start out when coasting, but soon enough it'll be happening constantly. Take it to the dealer, they will install the new inner wheel ends at no cost. It's common enough that ford has a "on the shelf" repair kit. My 2014 has been plagued by this problem since new. They fixed everything at 25000 miles but it's doing it again at 30000 miles. I will never buy a ford again; it's time to sue. Good luck.
Edit: I did find reference to the TSB, # ASI-32235, but still couldn't find the full PDF or complete language from it.
I also found this other thread, https://www.f150forum.com/f38/2013-l...287724/index2/ , which includes a video that is the exact same noise as I have.
