Does it engage when hubs are set to manual? If no, then it could be a solenoid. If yes, might be a vacuum leak.

I was able to get driver side hub to turn manually. Couldn't get pass side with out adjustable wrench to turn. Took both hubs off, lubricated, installed, turn to auto, Now it works fine.

That's great, I still don't understand why Ford chose to put such a flimsy hub on a great axle, it's pathetic. I'm glad you got them fixed.

They had to give Team TFI *something* to do once TFI was obsolete....so they figured "we'll have them design lockouts, how bad could it be?"

Real men always get out to lock in hubs.... Snapped, vacuum and water leaks, frozen internals, screw the auto hub. Nice set of Mile Marker 449ss's on the early, 549 on the later 60's. Never leave you stranded. You know that axle is locked when you feel the click then the clunk.
