Default Disengaging 4, Engine off

Is it possible to disengage the transfer case, when there's no vaccum from the engine?

I believe my truck was in 4 low, when it was parked.
front wheels were spinning opposite directions when we dragged it out of the field. luckily snow is slippery.

I'm still waiting on parts, before i can try starting it, and it would be nice to be able to roll it out of the garage while i wait.

Tow truck driver was nice enough to get it into the garage, but placement isn't optimal.

Your front tires should never spin in the opposite direction to the rears in 4wd. You have a transfer case. Not a differential in the center. Spinning in the opposite direction would be very very bad.



The front diff is open so the front wheels can spin opposite of one another.





No vacuum is used in the transfer case. Push the lever forward following the directions on the stick.

Is it an auto or a manual? If it's a manual and you take it out of gear (put it in Neutral if its an auto) it will roll around regardless of whether it's in 4WD or not. If there's something really wrong with it and the transfer case won't let go and you can't get it out of gear/in Neutral, you can unlock the hubs (if you have manuals) or if you have the automatic hubs, remove them and throw them in the trash as they suck anyway lol.

Manual trans, in neutral. tried shifiting the transfer case at the time, but i don't feel any stops, and didn't see any change.

Deerhurst:
I was referring to the front wheels only. when dragging it backwards in the snow, the passenger side was rolling backwards as expected, but drivers was spinning forward... like when you have both wheels off the ground. you spin one wheel, and the other side rotates opposite.

This would indicate to me that the hubs are locked.

OldGreyBeast:
When you say remove the automatic hubs, I'm guessing you mean replace them with manual ones?

I'm not familiar with how the automatic hubs function on this 95. I assumed they were like the 90's chevy trucks which required vaccum assistance to engage 4...

Yeah throw those autos away and get some manuals. I run Warns on mine, I think DH has Mile Marker on his. The autos on this truck use a ratchet and clutch type system, so putting the truck in reverse is supposed to lock them in, but the parts get worn. It doesn't take much wear at all for them to get janky.


Unless something in the diff is borked I've never seen it rotate the wheels in a different direction while it was being towed. I've scooted mine around in the driveway a lot with it out of gear and even with the hubs locked the wheels still move in the same direction.
