Okay. If you have auto locking hubs like I do on my 89 suburban, they
are designed to disengage when moved backwards in 2wd. The fact that
yours were really hot is not a good sign. While my hubs have been
trouble free since it was new I have never had mine towed. At this
stage of the game I suggest that you pull one of the hubs to inspect
it and see if it has been damaged regardless of whether they start
working again on their own which I think is not too likely anyway. It
does not sound encouraging. There may be some liabilty on the tow
company as when in doubt they should use a dolly. You do have my
curiousity up though and I will have to refresh my memory on the
internal design of them. I have had mine appart a few time to check
lube in them and they come off easily. Make sure you do not loose the
little bearing that rides in the end of axle stub inside of hub when
it is in 2wd.

I have the factory manuals here and I can post info on request but my
site is down for moment because of server hardware issues. I am hoping
the it is back up today as it has been down for a few days. As far as
the hubs if they need replacing, if they are toast it would be cheaper
to put manual ones on at this point.

Not if you brought it damaged parts and bills. If they say no, take
them to small claims court because they are most likely liable.

It is in the hubs, not Tcase. There is a clutch in them that is
activated in reverse when not in 4wd that it seem can burn up when
towed some distance in reverse at speed. The clutch only would when no
drive is applied to axle irself so it is not a issue when using 4x4 in
reverse. I am going to have to pull service manual tomorrow and
refresh my memory on that hub design. Mine have been trouble free for
18 years and 180K miles. I do check the gear in them every 5 years or
so. I do not run it in mud and such as it is a family travel vehicle,
not a off road toy so it does not see 4x4 used much maybe once or
twice a year these days. In its younger days it was used more.
