Driveline clunk or transfer case chain stretched
I have a 2011 escalade EXT 6.2 custom cam, longtubes, had a terrible clunk while accelerating from low speeds shortly after having the motor work done. Replaced front differential bushings and the transfer case (was told it was upgraded with a custom 50/50 planetary. Truck is so heavy that I wouldn't notice any torque steer from the additional power to the front. 4 months later and I have the same clunk while accelerating and decelerating, mostly at lower speeds. 20-2 mph on the deceleration. And anywhere on acceleration if I tap the pedal.

I had a clunk for a year or so. I greased my driveshaft yoke and it went away. I've read some threads about an updated yoke from GM as well. Not sure if yours is the same issue as mine.

the last time my chevy had a clunk i swear I checked everything and did everything everyone said. The only thing I overlooked was u-joints. When I shook everything down it was tight so i gave up. I finally replaced them 6 or 8 months ago, silent. not saying tis your issue just might be worth investigating closer than I did.
