OK, I have a 99 PSD F-250. I have locking Hubs, FREE -> LOCK. NOW I am familiar with the turn **** on the dash, thats what we have at work. ANd my old jeep has the 4X4 shifter on the floor and only that no hubs. What is the process now. Lock the hubs during incliment weather and shift it in from the floor when i need it ? Is there a way to do it without the hubs? Whats the deal? The manual didnt seem to help much.
In conditions where there is zero chance of needing 4x4, you should turn the hubs to FREE. The idea is that it saves all the wear and tear and drag of all that front stuff flailing around at road speeds. If you think you will need 4x4 (bad weather day, or even "all winter" for a lot of folks) then locking them in before you set out allows you to go into 4x4 by just pulling the lever on the floor. Or you could wait until you got stuck and then wade out into the muck and try to lock them...
If there are long periods of time when you don't use 4x4 (like, 3/4 of the year for a lot of people), then you should lock the hubs in (but no 4x4) for a few miles every once in a while, just to keep things from seizing up from lack of use.

I guess I wasn't too clear on that explaination , thanks Frobozz .
Mustang, are you sure it says lock - - - Free? I thought that all of the 99s and up where Lock --- Auto, at least all of them that I have looked at are. In that sense, if your does indeed say auto. the auto section works just like an automatic locking hub, put it in 4wd and go. The lock section also is beneficial in this situation, the auto hubs are vacuum operated, if the line breaks or something else goes wrong, you can still manually lock the hub.
The Stick on the floor trucks will say lock - - - Free.
The **** on the dash trucks will say lock - - - Auto.
This based on a visual comparison of my truck and my Father-in-law's truck, one of each.
I just keep it in auto and use the dash switch when 4-wheel is needed. My understanding of the hubs and switch are keep it in auto then turn it to 4-wheel when needed, turn to lock when you know you will be using the 4-wheel drive.
