Usually, yes, it could come & go though if broken pieces were moving in and out of the gears. Thats probably not it anyways.

From re-reading your original post, it probably was partially between the gears in the tcase and it may have been popping in and out of gear, that was the bucking you were feeling. Have you checked your tcase shift linkage? See if it has any slop or wear in it. Sometimes it can be adjusted or something may just be loose.

Drain fluids in both diffs and see if there is metal in the gear oil. Could be a ring and pinion, could be broken spider gear. Could also be a lose pinion nut (involves removing the drive shafts (14mm bolts PITA) from the diffs, There is a torque spec) I'd check those things too, and count the driveshaft turns per revolution of tire.

I would never presume to know more than Randy or Mike, or anyone else really. I'm just sharing some of my experiences. I too have had pop out of gear that was related to worn linkages.
