So this is a new noise...(Jeep Squeal)

2004 Jeep Wrangler X
97,000 miles

I don't know if the video does it justice but its a similar to sound to the grinding of metal.

I have heard of a lot of people saying it could be the front drive shaft hitting the headers, but there are no signs of scrape marks on any of those two parts. Any ideas?

P.S. There is also a shimmy movement (Not death wobble) going on with the front end of my Jeep which started 2 weeks prior to this. Correlated?

I used the following diagram to locate all of the U-Joints and they all seem fine. Is the front drive shaft suppose to have as much play as shown in the video?

Check the cv in the front driveshaft. After you remove it, look in the end and see if the ball and socket are not wore out. Mine squeaked similar to that before it went out and tore my t-case in half

UPDATE:
So the squeal got worse, which led to a little more research and finally some action, it looks like I have this "angry sparrow" thing.

I read to remove the front DS and drive around as a process of elimination.

Squeal Stops = Something with or connected to the front DS is wrong.
Squeal Continues = Remove Rear DS, put in 4H and see if problem persists.

My squeal continued after the removal of front DS but ran out of time. I will be removing the rear DS later tonight or early tomorrow.

NOTE: FOR THOSE OF YOU THAT HAVE A ROCK GUARD (transmission support? Idk what its called). It is MUCH easier to reach in from the rear and have your arm pass the Transfer Case than to do it from the peep hole or the front.

P.S. Still wondering if that is too much play in my drive shaft shown in the video above.

I'm far from an expert but both my axles have approx that much play, just had a shop check my front and they said all is well, so I think that is normal.

It does look like your pinion seal is leaking pretty bad, you might want to take care of that.

Be sure to put the front drove shaft on, remove the rear, and see if anything changes.
I tried to skip that step and turned out the issue was in the rear shaft even though it felt like the front.....

Yeah,

I guess I wanted it to be front, so thats where my mind was telling me to hear it, but when I took it out with no front DS, the noise was clearly coming from the rear.

From what I have read so far on the forums, its ok to have play in the driveshaft, but not at the U-Joint itself. Is this an example of a bad U-Joint? It's my rear driveshaft connected to the differential.

Great...just check shipping costs. Some outfits sell cheaper, then rip you on shipping.

Your gonna have to use a breaker bar ie a piece of pipe on a half inch ratchet probably gonna have to try and bench press your jeep to get it to break lose. I just did my rear pinion seal and I was able to get underneath of it enough to put my feet on the opposing side frame and pull on it with all my weight and get it to budge.

PROBLEM SOLVED

So I ended up just fixing the U-Joint on the rear drive shaft and not replacing the pinion seal considering it wasn't the diff that is leaking. I am leaving the front driveshaft off until I can find a way to get that nut off (probably will stop by the auto hobby shop on base when I get a chance).

So in the process of replacing the U-Joint, I ended up bending the bar on my vice lol. It was getting warm from all the flexing so I had to put ice on it on the occasion to keep it cool.



I used this guys video to guide me through replacing it the U-Joint on my rear shaft:



I originally was going to use his hammer method but the drive shaft was denting, and I wasn't comfortable with that. When I took the caps off the U-Joint, it was obvious they had gone bad. The needles were disintegrated.



New U-Joint is in, and the "angry sparrow" sound is gone!

pinon nuts are tight with over 200lbs at least my rear was.. be sure to know the exact amount as you will need to put it back on with the exact amount of lbs or else it can mess up your gears. Some say you need a new crush sleeve, but after I did the rear on mine, i took it to the shop to check gear backlash as a just in case.. all was fine...

When you pull the u-joint cups off to assemble the u-joints, make sure you look closely inside the u-joint cups. I had 2 spare needle bearings sitting in the bottom of the cup. They weren't missing from the cup sides, they were just extra. Definitely remove those extra bearings if you ever see them. First time I ever had that happen to me.

If you mean why is your post so wide, that can be fixed.
When you want to attach a picture to the forum, open it using "paint". It's already in your computer.

Towards the top left of the paint page, you can see where it will allow you to resize your picture. Make it smaller there.

Do that first, save it, then post it to the forum.
