I'm having a hard time finding a full list of service intervals such as transfercase, tranny, diff, etc. The oil, fuel filter, coolant is pretty common knowledge. Can't find anything else.

 

Have you looked in your diesel supplement manual?

If you don't have one, owner.ford.com - put your info in and you can get or read a copy online. It's all in there, including the definition for severe service schedule. I could spout it off, but I have a 2015 and while I doubt it, it *might* be different for 2014...

 

I never got the supplement with the truck. Thank you

 

This is the 2015 manual, but it should get you close:
