Loud noise coming from under the truck 07 sierra

Is it possible your exhaust is vibrating on the metal bar that is bolted from once side of the frame to the other, im pretty sure its so if the drive shaft fails it doesn't hit the ground. And it might be the center carrier bearing next time you drive see if the noise goes in sequence with the bumps in the road and if it does then thats a good sign it could be the center carrier bearing.
