98 tj 4 wheel drive

Hey all, new guy to the board and a new jeep owner. Always wanted one and finally got one. So here is my question. I have what I believe to be dana 44 front and rear ends, with the front having lock out hubs. When I lock the hubs in and without the transfer case shifted to 4 wheel my front end is in 4 wheel. Transfer case problem? What should I be looking for? This is all new to me and learning as I go.

That's not normal, my bet is your t-case shifter mechanism has slipped out of adjustment and it's not really in 2wd like you think it is.

Thank you. I will get under there and check to see if I can see where it is supposed to be when in 2 wheel and where it actual is. Thanks again

Well I pulled out the shift linkage and moved all the way into what should be 2 wheel drive and it is still in 4 wheel. I pulled the fill plug and it was a little over full but not bad. I then pulled it out into the back field and tried shifting it under the truck, 4 high works, neutral works, 4 low works but it will not shift into 2 wheel. The lever on the transfer case clicks into position like it has shifted but when I spin the tires the front ones still turn. Any other thoughts? Thanks again Paul

few things... 1. going from 4wd to 2wd.. did you try backing up a few feet to see if it unlocks from 4wd....usually not something you would do with the 231 t-case(assuming it is one) but couldn't hurt at this point.. 2. is a 231 t-case? 3. might be an internal issue...

Yes I tried backing up and yes it's 231 transfer case.

One thing to know about the 231 tcase is that it will not immediately switch back to 2wd after having been in 4Hi. I usually have to drive mine a short distance before it completely shifts all the way back into 2wd and the more gas I am giving the engine, the longer it takes. I dunno if that's related to the issue or not, just throwing it out there.

Thanks Jerry, I tried driving it to work and back today. 30 miles each way and when I got home I locked the hubs in and spun the tires and its still in 4 wheel drive. Guess from the looks of it, I will have to drop it out and see what I can figure out. I have never had a transfer case apart but how hard can it be right? Whats worse case, my transfer case doesn't work?

What do you mean "you locked the hubs in and spun the tires and it's still in 4 wheel drive"

Take your front drive shaft out. It's 8 8mm bolts and then tape a camera under your jeep and see if your front output shaft spins when you're driving. If it does, you're in four wheel drive. If it doesn't, you're not. The four wheel drive system has nothing to do with your locking hubs. All it does is engage a chain inside your transfer case to drive your front output shaft.

My wife's garden is not planted yet and I pulled out into the garden locked in the hubs and spun the tires and front tires dig like its in 4 wheel drive. Shifter has been in 2 wheel since yesterday about 70 miles ago. I can remove the front drive shaft and put a camera on it if you think I should.

Easier way if you have manual hubs lock them if not they are always locked

Jack up front so both front tires not touching the ground ( both in case you have a front locker or limited slip)

Leave back tires on the ground

Now hand spin one front tire and observe the other front tire

If cannot hand spin your tc is in 4wd and you have locker or limited slip front Diffy

If hand spin one tire and other front tire turns opposite direction you have an open front Diffy so then drop one front tire to ground and only have one front tire jacked up. If you can hand spin that tire your tc is not in 4wd but if you cannot hand spin it the tc is in 4wd

If it really isn't returning to 2wd the likeliest issue is the return spring. 4wd high to 2wd relies on a spring, which is why, as Jerry described, it doesn't always shift immediately if the drive train is bound up. Shifting between neutral and 4wd low does not rely on the spring which is why everything may work normally except for shifting into 2wd.

The NP231 is a simple system and quick/easy to pull.

EDIT: Actually I lied, neutral partially relies on the spring. Two things happen when you shift into neutral, the input gear is disconnected from the main shaft (not reliant on the spring) and the chain drive sprocket is disconnected from the main shaft (is reliant on the spring). Another test you could do is put it in neutral and see if the front and rear drive shafts are still locked together (they shouldn't be).

Well what I was getting at is that the locking hubs should have nothing to do with the equation.

If it's in the 2wd position, and your front wheels are spinning, then your transfer case is the problem.

I am not sure I tested the neutral position properly or not. Transfer case in neutral, jeep in gear will not move. I then tried to spin the front driveshaft by hand and it turns the rear drive shaft also. The spring that you refer to, do I have to drop the whole thing out to replace it or is that something I can do in place? From your explanation I would say the spring sounds like the faulty part. Thank you all for the help. Paul

I can't say I've ever spun a yoke on the drive transfer case with it in neutral.. I can check on my 241 that I have out when I get off of work in a few hours. I would assume though, that the rear isn't supposed to spin.

You could leave the case in place and just go at it, but it would be loads easier if you just took the case out, then apart. Sounds difficult, but if I can remember, it's five bolts that hold it to the trans, then you take off the dust cover for the drive shaft, slide that puppy out,disconnect the speed sensor, then disconnect the shift linkage. Sounds like a lot of work, but if you've got some time on your hands, it's more labor intensive than it is technical.

You can leave the transfer case under the Jeep to split it open. Doesn't take much longer though to just pull the whole thing. In the picture you can see where the spring should be sitting on the shift rail.
