Jk vibrating horribly

My moms jk (I have a tj) is vibrating horribly at all spears. It's acting like a vehicle that is out of Aline would but doing it all the time. Sometimes when you stop and start back it takes it until about 30 mph to start doing this but does it so bad the jeep is hard to control. Any ideas?

What year is it? Is it under warranty? Has it been modified any in the past? Has she hit anything recently such as a curb? Does anything look bent? Are the tires inflated properly? Any bulges in the tires? Any sign that a tire weight may have come off? Is it extremely cold where you are and the vehicle has sat for awhile in one spot? Is anything loose underneath?

Sounds like death wobble to me. Some serious issues going on with the front suspension.

Do not drive it. Take it to a shop that knows Jeeps.

Any chance it could actually be out of alignment? When were the tires last balanced? Could she have vent a rim somehow? If it's stock it's most likely not death wobble. How are her tie rod ends?

Sounds like Death wobble.
Worn track bar bushings, loose tack bar bolts, bad ball joints.
100% front end check is needed.

^^^Watch the video's!!!!!
What your are describing, sounds like the dreaded Death Wobble.
Lifted, or not, it can still happen!!!

Track bar bolts loosen up, and elongate the mounting Brackets. (Number one cause)..........

I'm almost sure it's the death wobble you speak of. It's not lifted or modified it is under warranty. I believe it's a 2011 but not sure. It is under warranty. I will check the front end suspension in the daylight tomorrow before its scheduled to go to the jeep dealer. It def is not an alignment issue all the weights are there and it was just aligned 4 months or so ago. She hasn't hit anything but does drive it in the beach a lot since she lives on the island of carolina beach.

Once the dealer says their peace and fixes the problem. Let us know what they say.

I just had a drive shaft u-joint go out. Shook like crazy but happened even at lower speeds. Might be something else to check. I know at least one JK owner that had the same issue and he thought it was steering but was drive shaft.

Sry for the late post but the jeep dealer only replaced the track bar shock and said there was nothing else wrong. It doesn't shake as bad but still can feel it a little. I'm guessing when this shock wears out like the last one it will go back to doing the same thing

^^^The steering stabilizer is not the cause of your problem. It is only a temporary band aid.
Go back up to Post #7 and watch the two video's.
Also make sure that you don't have a bad tire, or bent wheel. If you have a Discount Tire store in your area, then take it into them and have them check it out for you.

I know this is a band aid. The jeep has a lifetime power train warranty and every time we go to a jeep dealer they are more concerned with trying to get us to trade the jeep on a new one to get out this warranty I suppose. I pretty much told them to suck it this jeep will never be traded as it is paid for already and they can just keep fixing it. Wheels and tires are fine otherwise the band aid track bar shock wouldn't have suppressed the vibration as much as it did. However I know the problem will more than likely return

You should not have to pay for repairs out of your pocket just because the dealer doesn't want to address the real problem. Since you are still under the factory warranty and this dealership has not fully resolved the issue at hand; take the Jeep to another dealership. Certain dealerships have the reputation of trying to spend the minimum amount of time on a vehicle under warranty since they don't make as much for the repairs.

Yeah, I would try a different dealer if they're trying to tell you it's all good now with just a SS. Either they don't know what they're doing or they don't care. Don't forget to check the ball joints for play too. Mine went bad at only 30K.
