I picked up a 96 F150 that the girl child and I haven't sorted out who will be driving it full time. Yesterday I discovered that the four wheel drive works well in the snow, but not in reverse. All 4 tires pull good forward, but neither turn in reverse. I could here a bit of grinding like the hubs just weren't locked all the way in.
Is this something common?
Is it something repairable?
Is it something that is going to make me cringe getting fixed?
Thanks for any help.

I had a ford with (automatic hubs) found out that when in revirce they automaticly unlock. Took them off and put on manual hubs.not cheep but not out of this world either

While I'm not against manual hubs, how do they work with push button 4X4? All the ones I've had in the past were with shifter lever 4X4.

Truck with push button 4wd won't know the difference if hubs are auto or manual, YOU will be the one knowing the difference by having to get out. Still just a spring pushing the splined collar to lock the hub to the axle, auto hubs do it when the axle shaft turns by engaging 4wd, and manual does it when YOU turn the ring. Push button or floor shift, Fords shift the transfer case electrically anyway, unless you are going to 4wd LO range. Very simple, just a convenience.

Had automatic hubs on one of my Scouts, and they worked fine in reverse, only time I needed to lock them manually was to get compression braking on all four wheels. That was only needed once, when I was coming down the western side of Black Bear Pass in CO after three days of rain. Had no idea that fine black gravel could be so slick with no ice. Managed to stop at the fist hairpin and lock in the hubs, making the rest of the trip down just interesting...and very slow....rather than the faster one we thought we were in for just over the top.
Axle should turn the wheels either direction, but the wheels should not turn the axles unless locked in manually. When they don't do things correctly it could be simple as needing to be cleaned and greased, or may need an internal part or two.
Pretty sure the Ford version was supposed to work the same as the Warns on my Scout, but my only Ford 4X4 had the manuals. Suspect that yours may only need rebuilding, but also that either rebuilding or replacement wouldn't be extremely expensive, or beyond the capabilities of a handy DIY effort if you are careful about following the instructions. I rebuilt the Ford manual ones and didn't have problems, and that was my only experience with them. Been too long to recall any details and they may have changed considerably by the time yours were made, so take the above with whatever amount of salt you think appropriate.

From what research I've managed to do, it seems that the automatic hubs put in these truck are no longer in production and nobody makes parts for them any longer. The only option for repair I can find is going to manual hub lock outs. Honestly I feel much better about having manuals because then there is no doubt, just lock them before I'm in a situation they are absolutely necessary. Now I'm on the hunt for hubs and someone with some experience willing to help me change them. I am going to check prices at a couple of shops to get them changed, but fear that might be a bit painful.

The manual hubs might help you pick up some mpg's too. And like you said they are pretty much fool proof.

Definitely not a bad option.
I had two Scouts, one with manual LO's and the other with Warn Auto LO's. The autos kinda spoiled me by letting me delay the use of the 4WD until actually needed. After getting used to that feature and then getting a later truck with manuals again, I did find myself way into some gooey stuff a few times before getting into the habit of stopping and locking in earlier. But I re-learned the former ways pretty quickly after a couple of times stepping into knee deep goo 8^)

I agree with JDaily....don't skimp on the hubs. I have made that mistake and replaced the cheap hubs with a good set of warn hubs after they broke in a couple months. I used the warn hubs for the next 6 or 7 years until I sold the truck.
