I was looking at a ford f350 super duty that my tire guy just bought and his hubs are interesting. They have two settings and they are not locked and unlocked they are automatic and locked. does that mean he has automatic hubs that he can lock if he chooses.
I own one. I normally run them in "AUTO". In this mode they are auto locking hubs, like the stock X (actuated differently, I think, however.) In "LOCKED" they are just like locked hubs in a traditional manual hubs vehicle. It's a factory setup.
