former 80 owner looking at a 100... (1 Viewer)

Looking at a 99 100-series with 250k on it...runs very strong, but what common powertrain issues come up around this mileage?....or at some mileage in the future...have no experience with this V8 or this front diff (2 pinion...heard it's a bit of a weakness...should I expect to replace with a 4 pinion before thinking about lockers?)

Sorry for my naiveté
