FOUND THE NOISE. Took it to a Chevrolet dealership where my buddy is the service manager. They put it up on a hoist and tested it running in 2WD and 4WD with no noises. Took it on a road test and heard the noise again. He concluded that something on the outside of the vehicle was causing the noise. At that moment the light came on!!! It's my BILLET grille that I had added. Came home and googled it, sure enough- another guy with Tahoe and same issue. Duct taped the loose ends and noise went away. I will be cutting some short 1/4 aluminum rods painted black and using epoxy to secure them across the loose ends on the back side. PROBLEM SOLVED.
