If you do not have the ESOF system, and have a complete manual system, consider yourself lucky. Many of us have spent a decent amount of time and money trying to convert a manual system.
The ESOF system can be a problematic system, and has proven itself to be rather
un-reliable leaving SD owners stuck in wet grass, or parking lots after a little snow. This is embarassing to say the least.
If you have a true manual system, you will find that the little bit of effort to get out and lock the hubs, far outweighs the eventual failure of the ESOF system.
When your hubs are locked, they are locked, and the same is true for the un-locked, or free position. with the auto / lock hubs and the ESOF system, that statement is not always true.
Stick with what you have.
To answer your question, it is difficult to convert to auto hubs. It's not just the hubs that change. You need a vacuum solenoid, gem module, lines, switches, wiring etc.
Consider yourself lucky.... believe me.. you don't want automatic hubs if you have a choice.
I had them in a brand new 97' Ford and they would engage on their own and then I couldn't dis-engage them.... leaving me driving down the highway with the front axle howling away..... Ford said "Sure..we'll replace them for you".......
The only thing is... they replaced them with more of the same junk..... and I continued to have problems..... so I just went and bought my own manual Warn hubs and never had another problem.
If I thought I might need 4X4 for upcoming terrain, I would just turn in the hubs and then pull in the transfer case when and if I needed to... and then turn the hubs back out before I got back on the highway.
I bought a new 2007 Super Duty with Automatic hubs.... So we'll see how these work... I haven't used the 4x4 yet.
It says it has the automatic system but it still has the manual looking hubs...... What's up with that????
I'm going to have to read the manual a little closer!!!!!
I myself will only by a truck with the manual hubs and transfere case,,getting out and locking the hubs is a small price to pay, to ensure your 4x4 system works,,instead of hoping it works,,when you need it,,you need it,,and it's there with the manual system !
Now I think Do%@* has a axle disconect system, without hubs, but is still operated by Vacum to engage the front axle,,have heard of trouble with that system to,,but possibly not quite as troublesome..,,manual hubs ll the way !
My 06 F250 has manual locking hubs. I have always liked automatic hubs. Did the SD ever come with auto hubs? Can I put auto hubs on my SD?
Thanks
My first thought would be, are you sure you have manual hubs? The auto hubs on the SD look exactly like manual hubs, until you get close. The auto hubs still have a hand lever. You have to get close and read the "AUTO" and "LOCK" settings.
I guess I didn't read the manual close enough but,,,, Why does the auto system on my new SD have LOCK and AUTO positions on the hubs??
Like I said,, I just haven't taken the time to read up on it yet...
In short, because the auto hubs are prone to failure and we as owners complain that we don't like them or trust them. So, Ford gave us the option to get out and lock them if we choose. For me, that means that when I am going to spend some time off road, I take the time to get out and manually lock them. Then I only unlock them if I'm going to get on a highway at speed. I don't like them locked at more than about 50 mph. Some guys lock them at first sign of snow, and don't unlock them until spring.
I think it's the best of both worlds myself. Auto when you just want to do a quick run in 4wd, and manually lockable when you want that.
The newer 05-07 hubs are a better sealing design. If you ever see the hub out of the spindle you can see they have much better orings and the end cap is designed better to keep debris out which caused them to lock up and not be turnable in the previous vacuum design, rendering you really stuck if the vacuum system failed and wouldn't lock in the hub. j
It is a far cry better than the auto ratcheting hubs of the old body style. They liked to unlock by them selves and didn't have an option to manually lock them in.
Hopefully they fixed the ills of the first vacuum hub design.
Well on a brighter side of this conversation I guess I am fortunate enough to say that I have never had a problem with my autos and I use my 4wd quite often. I have full confidence getting in some soup knowing that I don't have to get out and lock my hubs cuz my auto work really well. (Knocking on wood)

You probably do not have problems because you do use your 4wd often.
Blue Super Duty, I have a '97 also and would like to switch to manual hubs. Can you tell me where you got your Warn hubs, how much they costed and how difficult it was to make the swap?
