Howbdo I go about changing this bearing. Can i do it with the tcase in the jeep or not? If anyone has done this please let me know. Lastnight it started screaming after highway driving. Thanks

Front or rear?

x91j

Oops thought I stated that FRONT.

SeriousOffroad

You'll need to drop the t-case.

I strongly recommend doing a complete rebuild since you're going to have to crack the case anyway.

So no easier way huh. Darn that's what I was afraid of.

x91j

I was reading and it says that there's just a snap ring that hold it in. Can anyone elaborate

x91j

Now I don't know if it the bearing or not. I have no front drive shaft in so would the bearing still be loud?

Some pointers:
-Try turning the front yoke by hand w/the t/c in neutral and see if it is difficult to turn or loud to determine if it is that bearing (probably not that bearing you have your d/s out)
-If you are sure its coming from your transfercase, there is also a chance it could be your actual planetary gears. The needle bearings on mine were worn and caused the transfercase to vibrate and gave the same symtoms of a bad bearing.

It's coming from where the 4x4 shifter is. No vibes just a swirl sound when i drive and when i tap the has it sounds like marbles

Your planetary gears are probably fine, but sounds like you do have a bad input bearing. No way of really telling exactly what is wrong though until you pull it out and crack it open. Like Frank said, I would just plan on rebuilding the whole thing with new bearings/seals, and I would also get some shift fork pads while you are in there to replace those (I have worked on about 3 cases and they were all worn out and could cause a whirling noise if worn).

So there's no way to find out till I open it? I just put the trans and tcase in the jeep. Ugh. I wonder if its low on fluid. I checked it before I put it up and it seemed a little low. Could that cause it? Possible chain?

gvns8

Low fluid could Definitely cause noise. I would try filling it up (make sure the transfercase is in neutral also when you fill it I think I remember reading that in the fsm). If that doesn't work, you could always drain it and take a look through the drain hole to try to get a look at the chain and see if it is extremely loose, but it is pretty difficult to tell if a chain is worn by just looking through that hole.

Yea it sucks dealing with transfer cases especially if its your dd.

x91j

Thanks man i really appreciate your help. I really don't know how to work on a tcase that's why I'm scared to open it.

I'm in the same boat too. My rear output bearing is bad from to short of a driveshaft from my 4x4 conversion. Solution: got a 2nd tcase ready for a SYE

x91j

How did you determine your was the rear bearing?
