Jeep question: death shake.
Posted on 1/20/16 at 6:30 am

Morning fellas,
3 times in the past week while driving, my jeep erupts into a fairly violent shaking back and forth. I'm talking rocking side to side hard enough that I have to put both hands on the wheel to control the vehicle.
It seems unprovoked; I hadn't run through any giant potholes or smashed over a speed bump before any of the episodes. After 15-20 secs, it will spontaneously smooth out.
Any ideas or suggestions would be much appreciated.

Maybe a cylinder going out.
Any check engine lights?

Grab each wheel and try to move it from side to side. If there is any play in it you have a wheel bearing going out or something closely related.
Very similar situation happened to mine.
After that check you UV joints

Does it happen when you are cruising or accelerating?

You been in the mud lately? Make sure there aren't any chunks of mud on or inside the wheel.
If not that tie rod ends being worn out will do it too.

Its called death wobble. There are a number of things that can cause it. Like someone else said, start at the bearings and work your way in. Whatever you do FIX IT, don't just go put a steering stabilizer on it as that only masks the problem.

Death wobble? You tube death wobble and tell us if that is what it looks like

you may have thrown off a balancing weight. it happened to me.
also, is it happening when you apply the breaks? if so you probably have a warped rotor

Sounds like tie rods

This.
If you haven't heard of this, you haven't done much jeep research.

On my 09 it was a combination of things, cheap factory steering dampner, and track bar bolts/bushings.
If you have lifted your Jeep but have not installed a longer trackbar, you'll normally find that the trackbar is doing two things, pulling the axle over to the driver's side, and pulling the front of the Jeep down.
One way to test for wear in the trackbar bushing / bolt is to have someone start the Jeep, engage the parking brake and put it in neutral (park for an auto). Lay down in front of the Jeep. Focus on the bolt that goes through the bushing where the track bar mounts in the bracket there on the passenger side.
Now have your driver rock the wheel back and forth. Not a lot, just like: 2 - 10 - 2 - 10 - 2 - 10. As you watch that bolt look to see if the bolt moves, if the front end stays in place but the back end moves, and if there is any noticeable "catching" in the bolt/bushing. If any of that is happening, then the BACK side of the bolt hole is likely no longer circular or the bushing is just plain worn out. The trackbar no longer has a good stiff mount and even that little amount of give is enough to translate upstream and cause death wobble. After I fixed my trackbar issue I also put a better steering dampner/stabilizer on the front.
Like others have said there is lots of information on "death wobble".

This is the only answer. Its Death Wobble
Check your Tie rod conections, Track Bar bushings and or Ball Joints.
This is a somewhat fairly common issue with some Jeeps. Not all of them will have it, but the ones who do end up changing most of the front end suspension components chasing the issue. I never had it on mine, but know a couple people who did.
Good Luck

Pretty normal for a jeep. I wouldn't worry about it.

It's pretty common on most of these Jeeps with the straight axle and the fix really varies from vehicle to vehicle. I had it pretty bad on my 04 Grand Cherokee. Tie rod ends were replaced and it helped tremendously but still didn't fix it totally. Here is a video of mine that I took right before I had it fixed.

It's the jeep death wobble. Well known issue among jeep owners/drivers. If you can't find the cause of it call around to shops in your area that install lifts and/or know jeeps and have them look at it. You need to get it fixed before it causes permanent damage while driving

Don't do this, it is an indication of a worn or loose component(s)that won't get better over time.

I had that on my F250. FML, it was scary the first time it happened. The only thing that would reduce it was flooring the damn thing. Ended up replacing all of the joints and the steering stabilizer
