My dad has an 88 Bronco with manual hubs and a 351, mine is an 88 with auto hubs and a 302, manual hubs you get out of the truck, and turn the switch to lock them in (its in the middle of the wheel, its...pink on his) on automatic the hubs on mine are inclosed, and filled with grease pins and stuff, its the 4x4 auto-lock hubs, no way I can turn them on manually unless i get under the truck and use some muscle

I've been known to talk about automotive engineers in French on more than occasion!!

Wow, so many messages. On the newer super dutys the hubs look just like the manual ones. They have that **** at the center of the wheel that shows two positions Auto and Lock. You can lock them manually or leave it automatic. The problem I am having is that on Auto they do not work but when I try to turn them manually I cant, they seem stuck. I read people talking about warn hubs or somethin. Any info?
Thanks again!!

for those of you saying that your 4low flashes when your auto hubs engage isn't true, the 4low light flashes when it can't complete the transfer case shift due to too much gear clash (best to do this when moving VERY SLOWLY), foot not on brake pedal, and vehicle speed faster than about 3mph. there is NOTHING to tell whether or not the hubs are locked, unlocked, or even there. It's an entirely different system from the transfer case, along with all the buttons, lights, levers (if manual shift), etc...
i hope this cleared that up.

In the fully electric system you first have to figure out if its the T-case or the hubs and the flashing low range is the only way to tell that they didn'g engage except for one to get one's **** out of the truck...and look at the hubs.

ftrucktough, we were discussing electric 4x4 here. There are 2 lights! the 4x4 light tells you the thing is in 4wheel drive and the other for when its in 4wheel
If the autohubs don't engage automatically, the low rangelight WILL cause the low light tol flash. If you have autohubs an disengage them in 4x4 the will re-engage so the 2 wheel low thing don't work the way you said without manual hubs. The electric switches activate the t-case and autohubs.
There is only one motor, thank goodness!
There is an outside chance that someone already intalled manual hubs.

Hello all, for no reason that I can think off, the hubs in my truck are finally movable by hand. I guess that the 8 inches of the white stuff we got this weekend made it reconsider 
I was able to move the hubs manually and everything was perfect, I even went to a nearby industrial area to play in the snow with it
I have not tried the auto yet but having 4x4 on a truck like that in the snow is priceless no matter if it is auto or manual.
I will be disassembling them soon for inspection.
Thanks all.
regards,
jimmy

if your light is flashing you have not engaged the low range of the transfercase the hubs can be locked or unlocked it will have no effect on the low range light.

BTW when you push the low range button the light either goes on solid or flashes. Completely off is high range!!!
