4x4 Question

[Goose350]

How come on our trucks (Which are the only ones that have the Manual hubs) it seems that the SOTF never works? Then you go to a truck that just has the SOTF and not the Manual hubs and it works every time? Every other truck that I have been in their 4x4 works fine. Do they do something different than the Powerstrokes do?

what hubs do you have are they the ....lock and free ones.....or the lock and auto ones ....

[Goose350]

They are the stock ones w/ the free and auto. But what I am saying is that for a lot of us the shift on the fly doesnt work but when we lock the hubs it works. Then you take something without the hubs and the shift on the fly works. Do those trucks without manual hubs have a different system to engage their 4x4?

well ive never seen auto/free hubs .......its either auto/lock or free/lock............as for other trucks i think they are electronic locks ..........ours work off of vacume if you have the auto/lock ones
