Question about Cars & Trucks
That is a common problem with various locking mechanisms. Short of taking the whole works apart for service quite often reengaging the Hubs and then disengaging them will fully separate the locking mechanism and the noise will stop. But at some point you need to pull them apart and service the assembly.

I have a similar issue on my 2001 F250. Apparently there is a technical bulletin that describes cleaning the hubs to prevent small plastic engagement lugs within the hubs from partially engaging the hubs without being "instructed" to engage. This causes bearing-like vibration & noise. We cleaned my hubs at a local truck & car service shop (owned by neighbor) and the problem went away for 1 week. Its back now same as before. I don't have a solution and am thinking about trashing the factory hubs and going with maunal Warn hubs or equivalent. Anybody else have any solutions?

This sounds like the front hubs are trying to engage. This motor/4wd is real susceptable with vacuum problems. I let my oil get real dirty and it caused the low vac.The dealer performs vac test for front IWES (3c247) and found both of them leaking out of tolerance. This also caused damage on the splined contact points so they had to replace both front wheel hubs (1104)

most likely a thrush washer is at fault since the 4x4 kicks in for you
Have a trans shop give you an idea how much to repair before you grind this thrust washer to bits
