Most dealers don't have a clue about about the 4x4 system.
I did have kirkland Ford look at my differentials since it was puking oil when I had the transfer hubs engaged. They found I was missing the overflow tube. I installed that myself and changed the diff fluid myself too. Kirkland Ford also said they would do a full front hub service but for $350 and of course they are not that familiar with the Dana 60 since they come off an older Ford.
I have yet to find a place that will do the 4x4 service.
