Fellas!

I just upgraded to a super duty from an f 150. Manual hubs are new to me and winter is over. Should I leave the hubs on on or auto for the summer? I won't use 4x4 until october when I hit the longing road for bow season.

You want to leave them on auto so they are not locked in full time. You will get better mpg and less wear on the front end parts in auto. If your esof (electronic shift on the fly) system is working properly you should be able to leave them in auto and just flip the switch on the dash to get into 4x4

 

To avoid future confusion, "manual hubs" usually refer to aftermarket hubs (such as Warn or MileMarker) that you must get out and manually engage.

The factory hubs are automatic- you leave them on auto, and if everything is operating properly, they will lock/unlock on their own depending on if you switch to 4x4. The manual lock position is just there pretty much for an "override" so you can lock them if they fail to operate automatically.

 

Leave them on AUTO as stated for better fuel mileage and what not. It's not a bad idea several times in the summer to put them in lock and drive around a bit like that. This will keep everything free and lubed in the front end. What I do with mine when it's raining and I know I'm driving straight for awhile....turn the selector **** to 4 hi and drive for a bit.....this exercises the shift motor on the transfer case as well as turning everything up front. Keep in mind don't switch to 4 hi at any speeds over 55mph....unless hubs are already locked.
