? on auto/locking hubs
2001 F350 the auto/locking hub on the passenger side looks to be roughed up, it won't turn, the text is wore off. Also the vacuum to that hub is missing. The drivers side is like new.
I'm not sure I understand how these function but I think if they are in the auto position and you flip the switch on the dash the 4x4 will engage at the wheels with the aid of vacuum, if in Lock position they don't need the aid of vacuum.
So my question is... if I find a used auto/lock hub can I manually put them in the lock position and have 4x4 when I flip the dash switch? And not need to worry about the vacuum line?

Not sure or you don't know?

And if you don't mind a couple hours work, you can swap to manual hubs from Warn or Mile Marker and get rid of all the vacuum hassle. Mine has Warns on it. Then you can also take care of all the HVAC problems that will probably show up in the future because of vacuum leaks.

Also is there a set number of shims/washers behind the snap ring on the axles?

It's easy but why would you want to?

For me, manual hubs is what I'm used to. Just prefer not to leave them locked all the time.
