has a very strange tire wear pattern

Shot is the dark but I know that those monsters have a great tendency to go through dust seals. And I know dust seals are the ultimate problem but I would possibly consider wheel bearings. My neighbor had a very similar issue. I have an excursion with the 7.3 diesel. Love the truck.

Smell of fuel. A leak does not have to drip but can seep. Follow that fuel line from tail to head.

You need to have the alignment rechecked. Sounds like the toe in is wrong. Rotate your tires every 8,000 miles as well.
