Truck keeps popping into 4x4 on its own
 

Every once in a while my 1996 Ford F250 4x4 will engage the front drivers side wheel into 4x4. Its really weird. You'll just be driving along then...poof! So you have to pull over, back up, and its fine. Any thoughts?

Does your truck have the electronic shift on the fly button/switch or is it the lever on the floor? I'm assuming your hubs are the autolocking. What does it do when it "engages"? It doesn't make any sense. Even if the hub is locked as long as the 4 high or low isn't engaged it shouldn't affect anything. It wouldn't pull unless the 4 wheel drive was engaged. The reason I was asking if it was electric push button was maybe the 4 wheel drive is kicking on for some reason which will then cause the auto hubs to engage into 4 wheel drive. Usually when a hub goes bad you don't get your 4 wheel drive when you try to engage it.

Its the stick on the floor. I found out a few days ago my 4x4 just isn't working, the bad noise is it trying to catch, it made a nasty clunk the other day. When we took it off road, tried to put it in 4x4 it wouldn't catch and we got stuck.:( Thanks for the info about the hub, I think thats probably the problem.
