Default Is early transfer case replacement a sign of an overworked engine?

I'm about to look at this '02 Sierra with 141k miles for potential purchase and the guy is having to wait on its transfer case to be replaced before showing it. I've seen a lot of trucks advertised, but not too many mentioning T case work being done at this early mileage.

Does T case replacement at 141k miles indicate the truck's been overworked with pulling heavy trailer loads? What signs of overuse should I look for on this upcoming inspection, keeping this T case replacement in mind?

Our 05 Suburban needed that at about 100-150k; google chevy transfer case slap should help explain possible problem. Ours failed even with no towing and we used 4x4 only a few times every winter. Apparently a common chevy problem.
