I went wheelin and now I have a wierd vibration when I drive. Its faintly noticable in 1st gear and very noticable in 2nd-5th gears. I checked the U-joints and the axles, so I ended up taking it to a garage and had them check because I am not very knowledgable in this area.... they found nothing either. They said all the U-joints weren't bad and nothing was lose. Since I have the lift they thought it might be because I don't have the spacers in to drop the transfer case, well I gave them the spacers and they put them in and absolutely no change... I banged up my jeep and I can't figure out whats wrong... crappy times.

You say you "banged up" your jeep. Were you in the rocks? Could have bent a drive shaft. Were you in mud? Could just have mud caked on the wheels, causing them to be out of balance. Could have just thrown a wheel weight.

Without pics of your drive line I'll have no clue as to whether or not it's a result of your lift, but I'd think the vibes would have been there before the wheeling if it was drive line angles.

Take out the front driveshaft, drive it down the road, then put it back in and take the rear out and drive down the road in 4hi. Any changes? If so, bent driveshaft, worn UJoint, or worn CV Joint on the front shaft.

I often get tire wobble around the 1st gear and then 40-50 mph range when my tires are out of balance or caked with mud.

Also definitely check the drive-shaft in the rear. I had a very strange vibration that I thought was a u-joint a couple of months ago. It ended up being my rear drive-shaft. After the snow wheeling season it was caked with salt and crud and stopped slipping when it needed to. I ended up blowing it off shifting out of first and taking out a muffler with it. :D

Both components are definitely worth while to look at.

Hey guys!! I went wheeling Friday up at bald mountain out of shaver ca also for my bday! Anyway I'm having the same problem as Jonhodge... While wheeling I kept hearing this clucking noise while I went to another gear (automatic) I thought it was normal and went along with the fun....

After I drove out onto asphalt I got the same vibration throughout the dash and floor board. The vibration is not really noticeable while off the skinny pedal but once I get passed 15 mph it gets bad. I also can't go past 65 unlike before I could hit 75 easy!!! I read many threads no this and like you guys recommended I checked tire weights for balance. I checked steering arms, lower arm bushings, u joints, driveshafts, and the transmission mount. I still have no clue what it could be. All weights on the rim were on. I have an idea of what a broke part looks like so I'm thinking its something I don't see or past my knowledge to realize.

I'm desperate so please any info or opinions would be awesome :))

The info is all in this thread. Did you rinse the jeep down real good including the insides of the tires? What kind of wheeling was it? Did you get stuck and need a tow?

You need to pull a drive shaft and take it for a spin. I would bet you bent the T output shaft. I have seen that a lot with 4" lifts that get used and flexed out, especially when a SYE has been avoided or even with a hack and tap style.

No tow. Wheeled on granite/ dirt I did not go through any mud or wet dirt at all. For any caking to occur. I did not hear a scrape nor did feel it while wheeling. I checked for scrapes and found nothing. I could say i flexxed pretty hard which leads me to brlieve that its the yoke/ driveshaft. Tmrw I plan to put the tj on stands and run it to check for vibration of the driveshaft/yoke , and hopefully I could find an answer their! Have any tips on anything while doing this ?

I finally got it out, took a ride on 4hi and no vibration!! So now I'm thinking the yoke is bent or my driveline is! And no I do not have a sye, I plan to buy one now that I need it
Are they difficult to install ? I have no experience with trannys or anything but I'm handy and smart ? Lol

Are they difficult to install ?
If you know how to read, and have a good set of external snap-lock ring pliers (there are a lot of similar pliers out there, look carefully at the pictures in the instructions and buy a good set for the intended purpose) you will be just fine installing a SYE yourself, in one afternoon.

I'd also recommend a stubby 9/16" ratcheting wrench for reaching some of the tighter clearance bolts to remove the TC from your Jeep.

Well thanks guys for all the info, always much appreciated. I ended up buying a procomp cv driveline and a sye kit with a short shaft. I payed 730 for both and 400 for labor. No vibration so it's running like a champ but for sure has been the most expensive wheeling trip I have ever had.
