Asked in Ford F-250
Do you have to unlock the manual hubs on a 2006 f 250 super duty that has a 2-4 wheel drive selecter switch on the dash?
Your hubs should have a "Locked" and an "Auto" setting. Under normal conditions, you should run in auto. Then if you need 4-wheel drive, flip the switch. Should the switch ever malfunction or go out, you have to manually lock and unlock (auto position) the hubs.
