Hey all quick question owners manual doesn't quite spell it out to good. The hubs on my 15 250 should be kept in what position, auto? And if I understand this with auto I can simply at anytime turn my switch to 4hi and go, the lock on the Hubs is a back up incase vacuum fails when in auto? Thanks always owned 150's new to superduty.
