chirping (from the drivetrain?)

I've got chirping coming from what sounds like the front end of the Jeep (hard to tell with the hard top on - I've been driving with the door open leaning out and trying to hear where it's coming from...super safe ).

It is related to speed, not RPM's, and it continues if I turn off the jeep and am going straight, so my assumption is that it's a drive shaft or something in that neighborhood. In addition to the chirping, I was driving up in deep snow last weekend and noticed that when I was in 4hi (Atlas II), there was a fluttering sound from the front end - not super loud, almost sounded like there was something wrapped around the drive shaft hitting the bottom of the Jeep. I didn't notice the sound when I was driving on dirt, so not sure if it's related to the snow, or if I just couldn't hear it on the dirt.

Any recommendations for troubleshooting & fixing? I bought the Jeep back in June - it's been wheeled hard, but has Tom Woods shafts, so I assume they would last longer. Did a couple searches on this and assume it may be the driveshaft or u-joints, but wanted your opinions.

Thanks! Ryan

That would be the first thing I would check. The Rear DS would generally be the one to go first as they are so short that the angle is more severe than the front, but it could be either. This sounds like what I was hearing a month or so ago . . . my Rear DS is currently with Tom Wood's getting rebuilt. Mine got really bad on the trip home from TDay, and when I crawled under the Jeep, I could actually feel the play in the DS by grabbing it and giving it a wiggle. If your noise is constant, you can remove the DS and drive around in 4WD to figure out which one it is. Here's what I've learned along the way . . . You'd think the TW DS would last longer, but chance are it won't . . . nothing against TW, but chances are you got a new DS because you needed a CV DS due to the severe angle of the DS in the first place which is problem #1 . . . the more severe the angle, the quicker it'll wear out . . . and the second thing is, the TW DS have a needle zirk fitting in the double cardan that needs to be greased from time to time . . . and apparently you have to remove at least one end of the DS to reach the zirk. If the center ball isn't kept lubed, you'll be rebuilding the DS a lot sooner than you expect. I live in SoCal where it's dry and mine only lasted a bit over 1.5 years. I'd expect in a wetter area, it would probably wear out even quicker.

I'd start by removing the front driveshaft and listen to see if the noise is still there. As superbly as Tom Wood builds his driveshafts, he can occasionally get a bad component used in its construction which can start squeaking.

My last TW rear driveshaft developed an intermittent squeeking that was hard to isolate because it was new and I assumed couldn't have been the driveshaft. It turned out to be the new Spicer CV centering joint had gone bad within its first 50 miles. Tom of course immediately took care of it and even sent me a new driveshaft rather than making me wait for mine to get repaired.

I have a stock front driveshaft but mine was doing the same thing at slow speeds it woud chirp and get a little louder and faster the faster I went. mine started after a wheeling trip to naches this summer. I searched around on a few forums and found out it was a thing people call "angry sparrows". All it was was a worn out cv joint in the front shaft. it was really easy to replace and I did new u joints while I was at it. you can get the cv at at napa but the are precision brand I think or you can go to a spicer dealer and get one just make sure its the right size for the u joints you have in the front I have a rubicon with 1330 joints and they gave me one for 1310 joints the first time.

here is a link that might help out if your going to try and fix it yourself

Yes, I agree with you Just rebuilt my CV joint on Front Drive shaft, I also put in SYE and new drive shaft from Coast. Also make sure you buy the dust cover that is in the CV joint on the Front drive shaft, My first one lasted 112000 miles and showed every mile of it

I've been having this problem for a while now and haven't been able to figure it out. So that's good to know. Would it hurt anything/help to diagnose this problem by spraying some white lithium on the u-joints?
