a torsion bar is the bar that is on an angle, it connects your front axle to the frame so that your front axle is shifting from side to side as you're driving down the road. mine went out a couple times now, but that happened because of what the lift kit instructions stated that you have to drill a new hole and slide the traction bar a 1/2" towards the driver side on the axle; well when you do that, what i didn't realize was that when you do that the bolt isn't allowed to tighten down all the way, so you have to replace that bolt with a shorter bolt of the same grade in terms of hardness. Also, the reason why the torsion bar tends to go out is because of the stress on the tapered joint at the frame that the angle of the torsion bar is at.

Let me get this clear. The cherokee doesn't have a tension/torsion bar. The only bars you have in a cherokee are a track bar (Panhard link) and sway bar (anti roll bar).
A torsion bar is a bar that is used instead of coil springs in front independent wishbone type suspensions, like in the Nissan Pathfinder. The bar is linked on one side to the A arm and the other side to the crossmember, parallely under the frame rail. When the suspension cycles the A arm rotates and "twists" the bar that acts like a spring.

...unless you're talking about a rear sway bar(which some XJs don't have and wouldn't cause his problem if his has one) XJs don't have torsion bars.
shocks? if the ride is bouncy, or if there is fluid leaking from the shock cylinder.
It'd be noticable, they are typically rectangular pieces of steel that are welded onto the driveshaft. if yours is missing one or is severely bent...most likely thats your problem.

x2 on the torsion bar not being on a jeep. Track bar or pan hard bar is what you are talking about. It creates the "DEATH WOBBLE" in the front. His vibe is in the rear. After reading all 10 pages of this, I agree with thesundancekid. Rotate tires to front and then check drive it. If you haven't jumped it or landed hard on it, then it is still probably your tires or rims. Make sure your lug nuts are torqued properly too. It does sound like you need to leave it at a reputable shop and let them find this out though. If you can't do that, and you can't fix it, drive it and suck it up, or sell it. Jeeps are tempormental b!+ches.

Honestly what are the odds that I put a bad tire on in the same spot! There's no way I did that 3 times. I'm getting my lift on next friday so maybe it will go away with the new leafs that arnt flat and new shocks. If not then its gotta be something with a minor bent axle. I live in chicago there are pot holes everywhere so I wouldn't rule out the bent axle shaft. Ill post back with my findings in a week or so. Like I said b4 at idle speed the jeep limps down the road.

Cherokee's don't have torsion bars. end of story. They have a front sway bar, and then a rear sway bar that is all but useless. The only other bars that they have are the panhard bar(also known as a track bar) and a drag link(not suspension related)

Wont stop shaking!!
Alright UPDATE. I just drove 200 miles this mornign and the shake is def in the rear. On a cold start when i push the brakes just a little bit it jerks me like they lock. I dont know id that is causing the shake i doubt it. Today i am going to check the rear brakes. U-Bolts everything seems nice and tight. Tires i just got them from a guy off CL they are only 2 weeks old and they have weights, he told me that they were ready to go. Alright so then i looked at my shocks and nothings wrong with em so thats ruled out. Now on to the Drive shaft, i replaced the u joints id say about a 2 months ago and the drive shaft looked fine (rusty but fine). So i dont know what is going on. the first week i bought it (july 27th or something) it didnt shake at all then after that the shake happend. so its been a good 6 month problem.
You may have a bad tire with broken belts inside the tire.Guys sell tires somtimes because they cannot get them balanced (broken belts will cause sever shaking)If money is short switch them to the front and see if the shaking stops in the back. Or take it down and have a tire shop check the balance.I had one tire that would only shake betwwen 40 and 45 mph and then it would go away. Good luck

High or low?
The driveshaft turns 3 to 4 times faster the the rear wheel, if its high rev vibration check your u-joints for ease of movement. A stiff or frozen u-joint will cause a high rev vibration. Check the front driveshaft cv joint for ease of movement. I had a vibration that was caused by the cv joint. The low rev or same as tire rotation vibration could be caused by warped wheel, out of balance or balance wieght missing from rear brake drum.
