Lock hubs for plowing?

[ParkCity.PSD]

Looked in the manual and it was absolutely zero help. I don't really understand why the hubs have an auto or lock position

Probably going to be plowing for the first time with this truck this weekend. Any help would be great!

Basically the auto position is to enable the "shift-on-the-fly" convenience. Flip the switch for the 4WD and vacuumn pulls the hubs in for you. No real sure for the reasoning on the lock position other than the fact that the vacuum system is so prone to leaks (thus no 4WD) that it is there as a backup so that you can still have 4WD even with no vacuum system. You can put the hubs in lock and leave 'em year round if you like. Shouldnt hurt a thing.

So then would it always be in 4wd or only when the switch is in 4x4? Is the lock like an override for the switch?

Use the manual hubs if you have failure. Most 05 and up won't. If you keep them locked, no it won't always be 4x4 but you be spinning the front gears.
