    I wonder if it could be the bushing in the transfercase/trans nose come. The the slip yoke slides into the trans. Crawl under and push up on the drive shaft near the trans to see if you can duplicate the noise. My 03 yukon was making a similar noise at shifts randomly and it turned out that the bushing was bad.
