Has anyone replaced or needed to replace the Transfer Case chain?

The issue, IMO, is that the pilot fit between the shafts is not continuously bathed in oil. It may get some 'splash' lubrication from the oil, but it is definitely not continuously oiled. With the FAD in operation, the inner shaft is spinning backwards at the same rpm that the outer shaft is spinning forward. With nominal 33" tires, that means the relative speed at the pilot fit is over 1000rpm at 50mph. With metal-to-metal contact of 2 similar steels, this is concerning IMO. That is why the plastic bushing was there from the factory - it offers a much lower coefficient of friction both with & without lubrication.

It does make sense. I suppose I can just do the FAD delete (hopefully it didn't do any damage already). Problem is, it's out of stock...with a 4 month ETA.
