I have 04 2500 4wd with electric push button 4wd. Transfer case is shot. Can I disconnect itand drive just 2wd? Or even remove it? Stuck here and could use some help please.

 

I guess it would depend on WHAT is wrong with your T case. All you can do is try.

 

Im new to the 4wd mechanical stuff. From what I have read these cases have a trend of pumps wearing a hole in the case and if you don't realize it the transfer case goes to hell. Well hell is where Im at. Can the case be removed or disconnected in any way to drive 2wd?

 

If you have a hole in your transfer case... No you can't just drive it in 2 wd.
Eventually it will completely grenade on you

 

As far as I know the 2wd 4l60 cases use a different tailshaft housing, or completely different housing all together. I'm not really sure, but you might be able to get a 2wd tailshaft housing and drive shaft and run 2wd only without the transfer case there ........ but I emphasize MIGHT. In fact, if you were to just ask me outright, I'd probably tell you no.

Actually, after reading this, I'm going to say that you either need to replace your transmission with a 2wd one, or replace your transfer case. Either way, you need to repair something no free repairs here unless you wanna try and JB weld the hole in the case ...

 

When you say the 4wd is shot, what does it do? Leak? Not shift? Clatter and scatter parts?
If it is a full time 4wd then you might not be able to disconnect the front drive line if it has a viscous coupling between the front and rear ends.
So, what are the options on the buttons? My GF's truck offers "2wd" 4WD" and "4LO".
The shaft going to the rear end always turns on normal 4wd rigs; when you put it in 4wd you simply connect the front driveline to the shaft going to the rear wheels. In other words, in most cases you are in 2wd already unless you put it into 4wd.
There is a seal between the transfer case and the auto trannys that tend to go bad, pushing auto tranny fluid into the transfer case and out the vent. An internal leak looks like an external leak...

 

Options are, 1 is 4wd as needed, 2 is 2wd, 3 is 4wd hi, and 4 is 4wd lo. As for case it was making huge noise on highway. Pulled over and making clatter noise and truck was jerky bad when moving. Towed to a spot and drove 10 feet and sounded like a chain in there off the gears. I pulled drain plug on case and doubt there was 2 ounces in it. Have drive lines dropped and case loose. Need to borrow a small jack to lift tranny to get T case out. Doing that tonight. If needed, can I pull the chain out and patch small case leak then put back together like that without chain? If bearings are still good that is.

 

There is a reason why your main output chain came off.. I'm guessing a bearing over heated due to lack of lube in the T case.

Hopefully you pulled over in time that no other damage was done in the case.
Easy and cheap fix. Replace bad bearing
Patch hole.
Replace fluid.... reinstall
