Unevenly worn tires can create enough difference to break gears in the diff.
If your ratio's are different, you more-than-likely would have broken the higher ratio gears by running it as much as you have already.

I'm really hoping that this is the case - the previous owner has been working on Toyotas for many, many years, owns a 4runner and about 4 other Toyotas, so I don't think that the mixup was done by him. The rear suspension is way out of alignment, in that the tires are bald on the inside, and have 1/4" tread on the other side. The front tires are pretty evenly worn, but are nearly bald. And one of them is about 10psi lower than the other three. I'm going to air the tires up better tonight, and then swap them around and see what I can figure out.
It seems to me that if the gears were vastly different ratio, it wouldn't be able to really drive in 4wd. As it is, you can ride the thing down the road in 4hi, it just doesn't sound good. Or feel good.
If they ARE mismatched, I'm going to have fun trying to distinguish 4.1 turns of the wheel from 4.3 or 4.8
