Transfer case thumping?

We've got an '03 Duramax FWD. Just went out in the snow(on road) and the thing started banging or thumping in the front end while engaged in four wheel high OR low. We made it home in 2WD but need to go out again soon. I went under the truck and don't see anything obvious. Driveshafts seem ok etc. Any ideas? thanks, Bob:humm::humm: I think it is a NVG 263 case. push button type.

Could it be the front axle actuator:humm: engaging/disengaging rapidly?
