2wd Or 4wd

I have a 96 2DR Tahoe. How can I find out if it's a 2WD or a 4WD?? Any help would be appreciated, thanks. It's a V8 if that helps.

Does it have any buttons or a shifter to put it into 4 wheel drive? If not, it is a 2wd.

WoW!

if it is 5-lug it is 2wd 6-lug is 4wd

I wouldn't worry about it, actually. My experience is that the tahoe defaults to a mechanical failure-induced 2wd anytime you actually find yourself in a bind and decide to attempt a shift into 4wd.
