2 wheel drive doesn't work, 4 wheel does

Hey guys I was driving home yesterday after picking up my girlfriend from work and we heard a pop. Then instantly it was as if it was put in neutral. I then rolled into a parking space and deciede to put it in 4 wheel drive and it works but only power goes to the front. Does anyone have any ideas? mabe u joints or transfer case. I just got a new clutch put in two weeks ago. Its a 98 2.5L 2in lift with 31in tires.

Have any way to have someone else drive it forward a little and see if the back drive shaft turns? I would think if it was the transfer case the back one would not turn anymore if it broke, but I really have no idea.

Did you, by chance, install a body lift? Could be something as simple as the shifter lever needs an adjustment so it will fully engage 2wd.

Could be something as serious as a busted up transfer case.

I'd check the shifter linkage first. If it isn't fully engaged into 2WD you can get those kind of symptoms.

I just did what you said and the drive shaft did turn.

That's because the other end of the drive shaft is hooked to the ring and pinion which is turning because of the tires on the ground. The rear drive shaft will always turn, same with the front, if it is moving.

blew out the rear end. put on the parking brake. block the rear tires and pull the diff cover. I am going to bet you have pieces of the carrier and bearings falling out of it. Sorry to give you the bad news. Hope for the best tho.

If the transfer case is the problem you will hear it when the jeeps moves forward and backward. If you had a new clutch installed there is a good chance the install wasn't put back the way it was intended. I'd suggest moving the shifter lever bolt to move it on the rod. Then manually move the tcase into 2wd. Then tighten the bolt back where it is suppose to go.

I'll try what you said tomorrow when there is some sunlight. I don't really hear a thing when I drive it at all in 4 wheel or 2 wheel or even when its rolling in neutral.

Thanks

Just sounds like your tcase lever needs and adjustment. Best as my memory serves me you need a 13mm socket and 2 minutes time.

Busted rear Diff?

I have a 2000 TJ with only 32,000 original miles I bought off my brother. I have a 6" lift running 35's. Last night driving down the road, I made a right on a tight off ramp and heard a pop then crunching noises and the jeep would not move. Put it in 4 wheel high and made it to a garage where they loaned me a wrench and I dropped the drive shaft and was able to drive home. I have no idea whether its the transfer case or the rear differential. Seems if the rear diff had broken pieces in it, that it would still be making noise as I drive. there is no shift problem. And if it were the transfer case you would think that it wouldn't drive in 4wheel drive mode. where do I start with this, and suggestions would be appreciated.

First, what do you have in the rear, a D35 or D44? With 35" tires I'm hoping it's a D44. If you have a D35, I would imagine you blew the rear as 35" tires are not friendly to D35's. If you pulled your rear drive shaft, you can still drive in 4WD because now you're just driving with the front wheels like a front wheel drive car and your rear wheels are just spinning along.

Thanks for the reply. Not sure which Diff I have, but will be pulling the cover off it today to take a look. I hope that's what it is because if its the rear yoke on the direct drive out of the transfer case, this will be expensive. How hard is it to repair or replace the gears in the rear. If that turns out to be the issue, would I be better off looking for a used rear and axel assembly or is it easier just to replace the gears in the differential.
