I did have the vacuum reservoir spring a leak. In my F450 case, you can manually override the hubs by hand. I don’t know if that is standard on most Super Duty trucks now.
Yes my 2001 ESOF hubs are also "overidable". However, even doing this doesn't work so it appears there is something inside both front hubs that are not working correctly. Could be gunked up with two much grease etc. preventing them from operating properly.
I've already performed part of the diagnostic routine and the dash electronics, transfer case & servo motor, and front drive shaft and axle connections all work as they should. Pretty much leaves the vacuum line or the hubs themselves.
