About 1/2 hour after it was off the wrecker, I noticed the front hubs were
hotter than a son of a ......
I tried putting it in 4H and 4L, but the auto hubs don't feel like they engaged.
In the mud, only the rear wheels would slip - it was definitely only in 2wd.
I'm going to let it sit overnight and try again tomorrow night after it's cool.
What's the consensus - am I screwed? If I'm lucky and it works tomorrow, is
there something I should do to make sure I don't do further damage? I'm new to
4wd, but handy in general with automotive work so I'm not afraid to rip
Thanks for any help.
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.
Yea, it's no better today after cooling down. Do you know of any good web
references that would show the guts of a system similar to this to give me
something to work with?
Also, in your opinion, do you think it's better/easier/cheaper to replace the
auto hubs or go to manual ones at this point?
I could try and go after the tow company, but I have a feeling that would be a
huge uphill battle.
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.
I agree with the SnoMan on this one. I used to tow for CAA / AAA an
they were always reporting to their drivers of vehicle claims bein
paid out for drivers negligence and not using dollies.
I myself have had my old 4x4 towed and had a few drivers want to leav
the front tires on the ground.
When I worked for CAA they specifically said not to tow th
auto-locking chevs unless on dollies or a tilt-deck tow truck

So, help me understand this a bit more. When you do tow this way, what is it
that gets burnt? Is it most likely the hubs or could it be something in the
transfer case? I have not done anything with it yet and don't need to right
away. This is not a primary vehicle for me.
As I said in an earlier post, I'm mechanically capable, but 4WD is a new animal
to me and I'm just starting to figure out how the guts work. If I know what I'm
looking for, I can probably do something with it.
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.
I think the only thing I need to know now is if I need one of these auto to
manual conversion kits that is sold separately from the manual hubs themselves.
I'm not sure what that is. I know I don't have the 3 hole cover which seems to
be asked a lot.
