So you have 4x4 when you engage the hubs manually, and not when you try to go auto?
If that is the case search under the ESOF hubs. That is the auto locking 4x4 that uses a vacuum pulse to lock and unlock 4x4. I did also read in the superduty forum in the last few days someone having an issue with the 4x4 and it ended up being a relay that was bad. He said that even a ford parts guy could not come up with an answer that there was a relay.

Your hubs are vacuum actuated. The ESOF going out is a very common problem. You probably just need this:
