Schmo Check the prices on a new one before throwing too much money at the other, especially if it's a stocker, or if the local shop tries to rape you like the guy that posted before . . . I didn't pay that much for a brand new DS let alone to rebuild one . . . 150 is about right for a complete rebuild and rebalance with new U joints and Center Ball.

After doing it a couple times you'll learn the trick to it . . . I don't see a reason to drop the skid, that is way too much work . . . they put those holes in the pan for a reason!!!

Finally got it loose. PB Blaster and a heat gun did the trick. My front driveshaft is in pretty bad shape. Debating on just dropping it off at a driveshaft shop and have them deal with it.

fifedawg I recently dealt with the Angry Sparrows.. in fact I named the D*mn jeep that because it caused me so much fustration. My sparrows were located in the rear driveshaft cv joint (centering ball disentegrated). I had to have a new one put on at the local driveshaft shop, cost me 390.00 for all the labor *ouch* but I didn't have the know how or time to fix it. I discovered it was the rear by removing the front driveshaft and then the rear. the easiest way that I have found for removal is to take off the skid plate, I know it's a PITA but it makes access to the bolts easier. (however, do not drive with the skidplate off.. it uh.. supports the motor) In addition I replaced the unit bearing on my driver's side in hopes to solve the problem.. so hopefully you won't have to throw as much of your checkbook at it as I had too.

Yes, could definitely be a sign of failure. It honestly is not bad to do; I wouldn't put it off any longer than I had to. I let mine go for about a month before I finally fixed mine and by that point the squeaking was much worse than when it started. You can take your front drive shaft out (eight bolts total, takes about 5-10 min) and drive to see if the sound goes away to make sure its the shaft that is making the squeaking noise. I've also had luck spraying some WD-40 or white lithium grease in the CV to see if the noise goes away temporarily. Either way its easy to diagnose.

If you don't need your 4WD you could leave your front drive shaft out until you get a chance to fix it, but like I said its pretty easy. Basic hand tools and an hour of your time. Check out Stu Olson's site if you haven't already.

Agreed... Just did this myself; I got 3 new spicer u-joints, but only replaced the outermost one that comes off to service the center ball. The old u-joints seemed to be in good shape (and they are easy enough to replace later on) so I decided to keep them in there for now and kept the one I replaced as a trail spare. Overall its a pretty easy fix, less than an hour total time; I did mine while I changed the oil.

When looking at the drive shaft that runs to the rear diff, there are two u joints (one closer to the front of the jeep and one closer to the rear). Are you saying the one closest to the front is the one I should replace or should I just go ahead and replace them both?

There are also u joints in the front wheels correct? Are those something that should be replaced as well?

Usually the "angry sparrows" noise that you described is associated with the front DS. I'd recommend removing the front DS to see if that is indeed the culprit and if so, you can opt to replace it (upgrade!!!) or rebuild it which usually consists of 3 new U joints and Center Ball . . . for the front DS. As you mentioned the rear DS (if a stock, non CV style) will only have 2 U joints and will not have the Center Ball. I'd recommend checking the U joints on the Rear DS and Front Axle while you are at it. . . check for any play in the U joints, see if you can grab the DS and shake it at all . . . it should turn a bit each way, that's fine, but there should not be any other play in it.

snwchris It's the (2) U-joints at the CV, near the T-Case output shaft and (1) at the Front Pinion of the DS.

Yes there are U-joints in the front axle (1) on ea. side

I typically replace all (3) Front Pinion and CV while the driveshaft is out, since it's easier that way.

The U-joint at front of DS at the Front Pinion is held in by plastic, so the best way is to use a torch to melt plastic, before using a Ball Joint press to remove the u-joint.

Schmo x2 on the front DS...exactly what I had about a month ago.

WinkyTJ Okay awesome hopefully that will take care of the issue. I will take a look at it tonight probably and let you know if your info helped. Thanks for your quick response!

snwchris Sounds like you have "Angry Sparrows"... which would be the U-joints in the CV of the front Drive Shaft.
Usually it's just a maintenance issue, since the U-joints are not able to be serviced, so you replace them.

You can remove the driveshaft to see if sound goes away and if it does then the CV needs to be serviced, which is usually (2) U-Joints and a Centering Ball Kit.

The easiest way I've found for removing is using one of the small ratchet wrench that the head folds over and using I think an 8mm socket. You should be able to squeeze it in there to remove the bolts.

There are a set up front on the pinion and the set my the T-case output shaft.
After removing the first (2) by the output shaft, put t-case in neutral and spin DS by hand until able to reach again, then put t-case back into gear.

Squeaky sound?? Drive axel??

Hello, I was driving my Jeep yesterday and started to notice a high-pitch squeaky sound coming from under my Jeep. As the day went by, the sound grew louder and louder and now its super annoying!!

Today I had a friend drive it really slow while I inspected it to find out where the sound was coming from, and my best guess is that the sound is coming from the drive shaft or something of that nature. The sound seems to be in synch with every revolution of the drive shaft.

I had gone out playing in some mud about a week ago and of course didn't wash her until yesterday when I noticed the sound. Could it be possible that the mud being caked on for that long could be causing my issue?? Thanks for your help!
