The front diff is controlled by a vacuum switch and cable. When mine
failed like yours (on top of Continental Divide in CO! ), it was due to
the vac hose having been rotted out from battery gases. The vac switch
is located on the right side engine compartment behind the battery.
(Roundish thing with a vac hose on one end, and cable to the diff on
other). The lever on the floor only controls vac to the switch, not the
front diff directly.

Well, my first 'sugg' is that you use punctuation so your post makes a
bit more sense. Then if there are auto-locking hubs check them.

the other guy is right...the vaccum switch could be the problem...you
should also check the electronic sensor that fits into the frony diff.
that was the culprit in my case
