4wd???

Okay why is there lockout hubs and a 4wd shift on fly? Do I have to lock the hubs to shift it into 4wd on the fly? Or is the lock outs backup ?

The two modes are free and auto. When in auto they lock when you shift it into 4wd. In free they remain free even if it is in 4wd.

Ok the hubs are auto/manual. This is how it was explained to me by a tech. For normal driving when 4wheeldrive is needed you can shift on the fly. For severe heavy duty work and needing 4wheeldrive manually lock the hubs in.

I think ford knew how crappy there hubs and auto-locking system is and knew it would fail. There for they gave you the option to manually lock them. I now have to manually lock them because my vaccuum system has a leak and they do not automatically lock out any more.

No the two modes are Auto and lock. Just like my 2002 F-250 says on the hub. It had an arrow pointing in one direction for auto and another arrow pointing in the other direction that said lock.

Yeah ford had issues with there auto locking hubs. My 99 rangers hubs went out and it was 1200 bucks for ford to replace them and noboby makes aftermarket hubs for them. So I scoured the internet and found that you can pull the hubs apart and pop the spring out and you have working hubs but they are always locked. I didnt care as I had 170 thousand miles on the truck and it was so much cheaper then the alternative.
