So im getting a terrible vibration from my Jeep. I think its either the driveshaft(s), blown tranny mount, (need new shocks), or something t-case related?
Ive checked
-Alignment is perfect
-tires are balanced
-u-joints are fine
It happens when im going over 45 and when i let off the gas it tends to die down a bit. My t-case shifter and tranny shifter dont shake (which i would imagine they would). Gas pedal and steering wheel vibrate. Any suggestions would be appreciated. Im gonna pull the front DS tomorrow and see if thats the problem. Pinion angle is pretty much dead on f/r.

Offline Possible issues:
Bad trackbar bushing/loose trackbar bolts
Bent/out of balance front DL
Bad front DL u-joints
Bad rear DL u-joints
Bent/out of balance rear DL
Bent rear output shaft
You also could have lost the weights on one of your front wheels.
I've had a broken motor mount before and it didn't cause what you describe. I'm not sure about a broken tranny/t-case mount however.
IMO the most likely problem is either a u-joint or something with your front trackbar. You should be able to see if you dented the front DL.
Let us know what you find.

Offline You said the tires are balanced. Did you get them balanced as a possible cure to the problem or are you assuming they stayed balanced and haven't had them re-checked? Speed sensitive wobbles usually come down to tires/wheels and drivelines.
I used to wheel a lot. . .

I will place 10$ bet on the U-joint in your driveline. ....Any takers?

I had the tires balanced and rotated right before the Rubicon Trip and it didnt change a thing. My front trac-bar is stock. I think its time to upgrade.. Any suggestions? The bushing is shot.

JKS, Teraflex and RE all make good aftermarket trackbar upgrades. Other brands do as well. It's nice have an adjustable model so you can center your axle each time you change your ride height.

Offline I've got a new in the box JKS front adjustable trackbar I'd like to find a new home for. I don't recall the part number at the moment but can post it when I get home this evening.

I think its home has been found! I could really use a new tracbar. Does it come with bushings or heims? Is there a bracket as well?

Offline Connor, you need to stop by Fred's, pick up the track bar, and come to my house Saturday and we can install it. :hack:

Offline I'm pretty sure this is the one I've got, but I'll double check tonight (it could be the OGS126) - http://www.northridge4x4.com/proddetail ... JKS-OGS125 It's got a factory style bushing on the axle end and Johnny Joint style joint on the frame end. No brackets are included. The hole in the frame end mount does need to be drilled out.
It was recommended when I downsized from the RE 4.5" springs to RE 3.5" but I found I was able to reuse my existing RE trackbar.

We could get a lot of work done on the Jeep...
Fred, ill take it! Hopefully that will put me one step closer to the problem.

If you come down this weekend don't forget to ask Justin for our sheels shopping list.
Check the rear diff. fluid and pinion nut? With new gears and bearings in that 8.8 it may have killed the oil as they all tend to run a little hot during break-in. Track-bar is most likely suspect.

I hope I didn't mislead you to think I was giving away the trackbar. I'll pm you a price I think you'll find fair. Let me know if you still want it.
The trackbar is the OGS125 I linked above. Here's a picture to show you it's still new and unused.

a little.. just a little. It has to be a driveline issue. Im gonna find time next week to pull my front shaft and see if thats the problem. Im hoping its just out of balance.

If you pull the front DL, why not replace the u-joints at the same time. Its easy and cheap.

Offline Bring the u-joints with you to the DL shop, pay them to put them in and then balance the DL. The problem will be fixed in one shot and for only a few bucks (+ the cost of the u-joints).

Offline Conner, didn't you just put a lift on that rig when you first purchased? Did you verify the DL angles ... especially the rear? It sounds EXACTLY like a DL loading and unloading by your description (ask me how I know).

Would you mind telling what DL show you would be referring to? Might be an option I need to consider in the next couple days as I tackle myself.

I'm a big fan of Driveline Service of Sacramento (in West Sac.). Quality work, reasonable prices, knowledgeable, and creative enough to deal with some of the "different" type stuff that comes up on a lifted rig.
