Gears are cheap, probably around $1K installed at a rear end shop. I bought a ring and pinion and did it myself on a chev once, the gear was around $400. Fords are usually really easy, since you can take the pumpkin out and carry it to the shop, you don't need to take the axle out. You are right, though - they last a long long time if the lube gets changed once in a while. The rear gear in my RV (converted MCI) has probably way over 2 million miles on it, and I ain't changin' it!

Rear ends are probably one of the least troublesome parts of a vehicle. Change the oil at 50,000 miles and use something like Mobil One synthetic. You probably would never need the spare.

If you decide to buy it have a shop that does a lot of axle work check it out. Specialty shops that work on a lot 4 x 4s do a lot of axle work. Unless they find a problem with it that will not cost much. They can also tell you what that axle is worth used.
Also make sure the brakes are compatible with your old axle. Or just switch your old brakes to this other axle with new shoes, drums, etc. if needed. Plus it would be a good time to completely change your brake fluid.

As long as the T bone wasn't on the wheel it will be ok. But as the others have said, you will probably never need it. Is it posi and yours isn't? Just a thought.

I have never heard of a rear differential used under normal conditions, i.e. not for racing, that has failed all of a sudden. When the wear gets to a certain point you should be able to hear a clunk in going into reverse or back into first gear. If it is quiet it is probably OK.
Easy enough to check on the internet to see if your truck and model year tend to have a problem with the rear end. If not then forget about it.
When I had a rear end redone on a truck of mine I had them put in new replacement parts as most of the cost was in the labor.
