Three of them had hubs that were either locked or free, and had to be changed manually.
One has automatic locking hubs that apparently lock in automatically when I select 4WD from inside the truck. No way to physically manipulate the hubs.
The new 2022 Lariat 350 has hubs that say locked and automatic. They get changed physically like the locked and free hubs.
I don't get it.
Can someone please explain to what I need to do in order to get into and out of 4WD with this hub system.
Thank you.
BTW, this truck has a 7.3 gas engine and I got 19 mpg on my last 180 mile trip, mostly highway but some stop and go.
I am certainly satisfied with that; I get 11 mpg in my 2002 250 6:8 V 10.
Leave them in the auto position and the hubs will lock when you select 4WD. The lock position is used in the event the auto locking system fails or if you want a faster response when engaging 4WD.

This pretty much sums it up. I believe the book says that if you are plowing snow or doing heavy off roading to manually lock them in also.
I special ordered my last two trucks so I could get the full manual system because I think it's the most bullet proof set up currently offered. I don't know what I'll do when I decided to get a new truck, guess I'll have to go back to the electronic system.
Only thing with the hubs now and the convenience of the auto engage in the truck is that the hubs should be exercised periodically just by turning the hub controll **** back and forth. I'll do mine once a month so they don't freeze up.

Do what I do and lock the hubs manually, ignore the auto system... I use 4wd a lot. I plow snow, I drive in 5-6 months of winter, I run lots of steep gravel mtn roads in the summer. I still find the auto doesn't work every time, or as quickly as I would like sometimes. If I need 4wd I manually turn them. If it is more of a maybe with low consequence i will use auto and usually it works fine.
I only manually lock them if 4WD is going to be needed for an extended period or if the conditions are extreme. I believe leaving them locked reduced mpg.
The problem with owner's manuals these days, especially truck manuals, is that they apply to many other vehicles besides the one you bought.
With the amount of options and features available on each of six plus trim levels, it's hard to determine if what the manual says applies to your vehicle, "if equipped".

And yet these hubs work the exact same as they all have in the last 20+ years....
My 21' is on the third set of locking hubs all under warranty. The hubs the truck came with and the second set did not last long at all but this third set has been holding up for a few months now. My next step will be to bypass the auto system and install a set of WARN hubs and be done with it.
