03 PSD 4x4
I looked at an '03 F-250 4x4...the manual hubs have positions on the dial for "auto" and "lock" instead of lock and free like it used to be. What's up with that?

The auto position is where you want to leave the hubs. They will lock AUTOmatically when you engage 4WD from the dash. The AUTO position is the same as the old FREE position.

If you do a search you will find a lot of info on this.
the lock position is a back up for the ESOF incase it does not ingage when you turn the *** on the dash for 4x4. If you have a manual 4x4 then it has the lock and off position on the hubs

I see. Well then, they should also include a manual transfer case shifter in the floor just in case the electronic switch on the dash fails too. 
The idea for the SuperDuty 4x4 system must be the result of one of those projects GM had their hand in. I say either put an automatic electronic system in, or put a manual system in. This idea of combining both, but half-way doing it doesn't help consumers at all. In fact, all it does is further increase the cost of an already overpriced truck.
Oh well...thanks for the info. guys...I was just scratching my head over that one.....

The ESOF system is fully "automatic". You should never have to get out and manually lock the hubs. It's just that you can if necessary. 
Personally, I like it and never had any problems with it in either my '00 F250 or '01 F350.
I think the manual override hub is actually more of a cost-savings item than an engineering feature. If I remember correctly, it's the same hub that the "manual" system uses- it's just that the manual system has the vacuum activation capped off. If true, Ford only has to buy 1 hub design and can save in both purchasing and manufacturing costs.

Not to worry, if you don't like ESOF then don't get it! It's an option, not a standard accessory. Personally, I like it -- but then again, I also like digital stereos instead of analog (I'll take the risk of a display failure vs. the old reliable ****), power windows (I know the motor may fail but your arm never will), and automatic transmissions (nuff said). In the end, to each his own. Like I said, ESOF is not standard & you are not forced to dealing with it if you don't want to.

in the auto position you need to be stoped when engageing into 4 wheel drive. if it is already in the lock position you can shift into 4 wheel drive at any speed.
so if the side roads have snow on them and the main roads are clear, you can leave them in the lock position and be going down a main road and turn onto a snow covered side road and go into 4 wheel drive without stopping.
thats why there is a auto and lock. best of both worlds.

When the hubs are set in the AUTO position, they will lock automatically, then unlock automatically every time you back up. Go forward again, and they lock again. Now let's see, under what conditions would continuous locking and unlocking occur, causing undue wear and tear on the components? SNOW PLOWING!!! Lock the hubs when you're plowing, leave them in AUTO when you're not: the best of both worlds.

Not true, ESOF = Electronic Shift On the Fly
I engage the 4 wheel drive while moving all the time from the AUTO position and it goes in just fine.
