Wj Squeaking Noise!! Need help

I have a 99 Jeep Grand Cherokee 4.0 with a 242 transfer case. There is a squeaking noise coming form under the jeep every time it is in motion. The noise gets louder and goes with the drive shaft, also gets high pitched and stops as I start to break. I took the front drive shaft out to see it was the double cardon was going bad but it kept squeaking.

Could it be the transfer case? I just changed the fluid in it a couple months ago. Is there anything else I can try to fix this problem? But I know its not the brakes definitely drive shaft/transfer case problem.

only when you're moving? check front brake pads...wear sensor is a metal tab that squeals on the rotor when you are moving. when you hit the brakes, it puts pressure on this tab and the squealing goes away.

Is your parking brake on or stuck?

Some more info about exactly when it happens would be helpful. I hear the swaybar and link bushings tend to squeak when they're in need of lubrication... Could be a thousand different things without some more details.

If you bounce the car up and down while stopped, does it squeak? If so, crawl under it and have someone else bounce it, see if you can get a better idea of where it's originating.

Have you checked your rear driveshaft u-joints? Also would just check to make sure no fluid is leaking out the rear axle. Since the sound is directly proportional to your movement, would start look at whatever is moving/turning as the cause, starting with the easiest first. Not saying it isn't the tcase, but have never heard one squeal at all. Wouldn't hurt to double check the tcase fluid and see if the output shaft is leaking.

The beatings will continue until attitudes improve!

The noise comes as soon as you go down the road. Both front and rear axles were replace recently and the front drive shaft has new u joints. The transfer case just had its fluid changed and there is no fluid loss anywhere that I see. I remove the front drive shaft and it still makes the noise, so I eliminated the front shaft from the equation. When I replace the front axle I checked the brakes and they were fine. The rear brakes I checked.

How can I check the rear drive shaft? Tips would be helpful. I'm hoping that it is not the T-case because they get expensive.

In the same boat you are!

So I own an 03 jeep grand cherokee, Not too sure with the model transfer case. But it is mechanical, not electrical to change from 2wd to 4wd. I know for a fact it very well be the transfer case causing the issue, I have sunk soo much money i didnt have thinking it was wheel bearings, brake rotors, real axle seals and more!!
So i have been ripping my hair out and feeling embarrassed from the squeal noise. I have also experienced hard shifts (clunking shifts), changing transmission fluid or transfer case fluid did not do any better. Or even adjusting the TV kickdown cable.
4 months down the road, the squeal noise went away. Now it sounds like a knocking noise where the spare tire is supposed to sit. Sounds like someone keeps knocking saying let me out! lol but Acknowledging the rear differential, fluid is still good and no leaks as of today 1/13/2016. wheel bearings are good. etc. The only reason why i have not fixed mine yet is because lack of cash for the moment. I love my jeep to death and its a major BEAST. I wish to just DELETE the transfer case and TANK it in the trash. I have been doing research and more research trying to find options on if i can even remove the transfer case, find adapters and longer drive shaft. I cant find anything. Very stumped on this! I NEVER had to use 4wd even in the snow and ice. Honestly when the jeep was given to me, i declared it as being jeep abused, little to NO maintenance what so ever. The spark plugs still had the factory ones installed after 168,000 miles on it. Only had 3 oil changes done, nothing else. All vaccume lines clogged with dirt, EVAC system rotted out, and i can go on and on.
But the main thing is, If there is no other option, get a rebuild transfer case. It be easier and less time consuming for your fix.
