08 Tahoe transfer case issue

Have you checked the universal joints? I had a bronco years ago that when the T case engaged the front driveshaft it would clunk like crazy. I initially suspected the T case to be bad and it turned out to be a universal.

X2, the universal joints would be my first move, they can make some awful clunking sounds and make you think that there is more of a problem than there really is.
