Typically you would want rear lockers if you can only have one.

My approach to a downed log is usually low range as I like using the engine for braking on some slow trails, bump the throttle to get up on the log and brake down the other side. The H3 in low range with an automatic changes the throttle response and I like the results and ability to manually shift the gears. I don't know if it is that way on a manual.
I think it is going to be one of those things with different opinions. Probably because of what you stated, conditions which cause you to want one. I have always been of the school of thought the rear was where you wanted it. That could have been that in the past, way past, that was all that was commonly available on other vehicles. In my case I use it the most when climbing steep obstacles. The H3 gets to a point the amount of ground contact VS weight comes into play and it looses traction. I can try that same hill with the rear locked and it so far has gone on up. Sometimes there is enough torque and uneven ground that the opposite front wheel from the rear in ground contact will pull up. So in my wheeling the front end is already light and may not benefit from a locker or put a lot of stress on the front end. (I'm still mindful of that)
I can see however on red rock where approaching a semi vertical rock face at first the front locker would be great. After getting the front end up and light, then the rear can push on up. Witnessed that several times in Moab.
Also for discussion sake, I was concerned about the aluminum front diff and really concerned about adding a locker. With the CI diff maybe not so much. However I still have not justified the front locker with the problems the other components seem to have. With a lot of weight on the tire remaining on the ground and locked there has to be a lot of pressure on things in the IFS setup. I pulled the trigger on an 08 knowing it did not have the front one but was concerned there may not be an 09. I also at that time found out from someone at GM that the locker could be added at a later date. Turns out they did keep making the H3 a couple years longer and with the front locker.
Here the front wheels had very little contact with the ground.
Several straight axle front ends before me did not make this steep hill with loose shale when they hit this place. I liked how the IFS followed the contour of this place and was told the fronts spun very little. I had the rear locked to make it this far and when I went off in this hole the rear pushed the front up on the next level. So I guess it is one of those never ending stories.
We were all impressed at this time in 06 how the H3 performed right out of the box as it was the first one to run most of these trails.
I still like mine enough to have traded for an 08 at the end of that model year as they were going away.

Agreed. Don't go with a front locker first! If you have only one locker, the rear locker will push you through an obstacle. A front locker will try and pull and drag you through...pair that up with weak parts and you can break things.
The only reason I considered a front locker first was when I broke my diff I could upgrade. I wouldn't use it until I added the rear for that reason.

Wow, well F5 has probably forgotten more than any Dealer knows, for any brand.
MOST Service writers are glorified Wal Mart Greeters. Infact I've only met 2 that weren't absolute idiots. They don't know half of what we know about our trucks. (Ask me how I know - my dealer rap-sheet is probably longer than anyone on this board
Picking your battles is how it works - argue with him when comes to something that is a matter of opinion, but when it comes to tech/wiring etc....F5 would know long before the Dealer Techs could figure it out.
With all the blah blah blah....it's simple.
Switches, (Panel) or Computer do not need to be reprogrammed. The Switch array is not tied to the VIN.
If you try to use the new switch that has the front locker included (late model) on a non front locker vehicle (early model)...it won't work period, for a NUMBER of reasons. Ask me how I know. In fact, I have a late model front locker switch panel FOR SALE.
You want to try?
Yes F5 can be cranky...but frankly I think it's part of his charm.
Dishing it back hurts us all.

No doubt Doug knows as much or more about H3s than anyone, anywhere. I have met very few service writers that could figure out which hand to wipe with, much less answer technical questions. We all have our areas of expertise and H3s, even though I own one, are not one of mine. H1s, even though I have owned a gaggle of then don't even qualify me to count them as something I know enough about to offer lots of advice on. That is one of the big reasons I enjoy the forums so much, you can learn from people that just solved an issue. Don't have to get the opinion of what it might be but can hear what was happening and what the fix actually was and all for free.
Doug cranky...I always thought of him more as being gruff.

Knowing a lot doesn't give you the right to be a prick. I asked for documentation to take to the dealer to prove them wrong, but that was ignored. I'm sure they won't all bow down in awe if I mention the mighty F5's name. If he thinks that he has the right to condescend, then he can do it elsewhere, or I will. Maybe that's not a bad idea.

The point is....they need to figure it out.

Don't see anyone taking sides, just moving things along. We all have our good days and bad days.
Nothing needs reprogrammed when replacing the 4x4 switches. They might need a vin for things like ordering the part or warranty but not anything to do with flashing the BCM for any reason. I think that you don't even need to disconnect the battery when replacing them.

I just want to say, I am sorry I ever mentioned anything about VINs and switches! Good grief! I still can't find where I got that from, I just know I was told that when asking about using a factory H2 locker switch for a front locker. I am now certain whoever told me that was incorrect, and did not know what they were talking about.
Again, sorry I ever mentioned it! F5, I have found you to be a great wealth of Hummer knowledge. I was not trying to question your experience, just mentioning something I was told, and wondering if it was true. It would be a shame to lose you here over something silly like this!

Have to agree that the actual switch panel has nothing to do with a vehicles vin#. As long as the switch panel has the same switches 06-08 rear locker or 09-10 front and rear locker that you are replacing there is no issues. Non Adventure/OffRoad H3/H3Ts will not be able to use the Adventure/OffRoad switch panels from any year to control a locker.
WOW, F5 blows another gasket, takes his ball and crawls home yet AGAIN (I"ve lost count on many HUMMER forums this has happened)!
F5 does have tons of knowledge of the H3 platform, but ALL the knowledge in the world does not give anyone the excuse to be "gruff", "cranky" or a giant whining baby without being called out for it! Nice to see someone else who is not trying to win a high school popularity contest by biting their tongue around the All Mighty F5.

I'm going to close this thread down. I think the question was answered: switches are not VIN specific but the ability to add a non-standard switch to a truck may be VIN specific. Discussion on the various posters' intent, emotion, attitude etc will simply be unproductive.
