Welcome to the ORG.
You'll hear this from almost every member of this board.
1.) Get and OASIS report from Ford. This show's what work has been done to the truck by the dealer under warranty. They can be pulled by dealership tech's, maybe a service advisor would be nice enough to help you out. You may or may not see head gasket issues but you may very well see EGR cooler and oil cooler related work done. Being pretty low miles you may not see any of that. If that is the case a replacement oil cooler EGR cooler (or delete) may be in the trucks near future to maintain it's health properly.
2.) Never heard of wheel hubs going out that quick. If I had to put a number on average wheel hub wear I'd say around 150k if it's lifted. Maybe less, maybe more, who knows... I'm at 93k with 37's and I have never replaced any front end parts or feel the need to soon.
3.) I do 5k oil interval's with at least semi-synthetic oil. Run at least Rotella T5 10W30 or, better yet, a full synthetic 5W40 of your choice. The injector's of these engine are happier as the quality (and price) of the oil you buy for it increases. Use only OEM oil filters. Change your fuel filters ever 15k, again use ONLY OEM manufactured filters (Racor/Motorcraft/International.)
4.) At least install a coolant filter and ensure you change your coolant every year or so if you run the stock gold coolant, which I do. The stock oil cooler and EGR cooler are just fine if the coolant is kept fresh and clean (with the filter.)
5.) Read as much as you can on this board. Most of the info on here will keep you out of trouble, even whether it's worth it or not. You'll find a ton of over-achieving info on here but hardly ANY info that will get you in trouble.
5.) Warm the engine up to operating temp before romping on it hard.
