Re: F100 4wd maintenance
Just do the basic maintenance you mentioned and you should be fine. Just be sure hubs are well lubed, u-joints, ball joints, steering components, etc. are greased, and whatever else you can find while you're under there.
You should have yourself a nice vehicle, but don't expect to be able to hammer it over and over with no consequences. It will perform well, but NOTHING is bulletproof.
Congrats on your purchase!
