I'm a bit late here but steering wheel shimmy is caused by a tire being out of balance, not alignment. Basic alignment specs are the same after installing a suspension lift except for the Caster angle whose optimal angle is reduced with bigger tires. The factory caster angle setting is 7 degrees with factory size tires but it drops down with bigger size tires... like 6 degrees is pretty optimal for 33" tires (but not critical) and 4.5 to 5 degrees is a good Caster angle for 35" tires. That's not to say everyone needs to reduce their caster angles if they have bigger tires as the caster angle is not super critical, within reason that is.

My death wobble experience.

i bought my 04 jeep brand new. it got DW about a month after normal driving. as soon as i got it i called the dealership in San Diego i bought it from. Rancho Jeep. well they picked it up and drove it and called back and said it was fine. so i picked it up. as soon as i got on the hwy it came back.
i turned around and went strait to the dealer. i showed the main tech the problem. he drove to 55 and BAM! Death wobble. he nearly crapped himself. they replaced the steering stabilizer and rebalanced all four tires. the DW came back a few days later. i took it back 4 times and got different treatments but the same results. i even had them change all 4 wheels and tires. after owning the jeep for 6 months i got deployed and left. jeep stayed parked for 4 years. when i got back this Feb i bought new tires. DW never came back. i then installed the ZJ/CV coil springs. no change. i put on new shocks to support the lift of 3.5 inches. no DW. redid the alignment aswell. still no DW. the other day i got a nail and had the tire fixed. the tech didnt rebalance the tire properly and the DW came back. i went back and had them rebalance the tire and it went away. it was the front passenger side tire. hope this sheds some light on someones probs.

I just purchased a used 2001 Sahara with a 3" ProComp lift and MT Baja Claws. Experienced the DW at low speed (entering highway ramp, I pulled to the side because it as so bad.)

I want to get rid of the MTs tires. Do you have any suggestion for a more user-friendly wheel/tire combo?

my new 2000 TJ has it at 55 mph. I am presently going through the remedies on this post to clear it up. Maybe Jeeps next Wrangler can be the DW (Death Wobble)

Bought an '06 Unlimited four weeks ago and was doing it frequently at 90kph (about 55mph). I could accelerate through it and it would go away but if I cruised at 55, it would amplify and get scary. After two unsuccessful balancing attempts, the dealer took the Goodyear Wrangler tires off and put on 4 Michelin Cross Terrain. That worked. After 500km of driving all is well so far and the Michelins have refined the ride overall too. Seems to coast more easily and a definite jump in range on a tank of gas. Hopefully I'm wobble free for good.

Two things I found interesting, one was the comment by Jerry Bransford referring to caster which is dead on as the cure. The other was the sport bike reference. Sport bikes are very responsive because their headstock angle is closer to vertical as compared to a cruiser (Harley Style) bike and therein lies the reason for the damper on sport bikes. I've had more TJ's than I would like to admit and I always crank in a couple of extra degrees of caster (the top of the axle tilted to the rear) and with all other pieces good, I've never had death wobble. If you have to have a steering stabilizer then you're wanting to look good or haven't a clue how to fix the problem. It's bad enough turning big tires in difficult situations without having to add the drag of a stabilizer. I bought a 04 Rubicon last Wednesday and it has a big old stabilizer on it, a 4" lift and guess what, the caster is at "0". It was a bargain because the owner got tired of dealing with, you guessed it, shimmy or as we know it, death wobble. He told me he had tried everything, bushings, track bar, balancing tires and they finally told him he had to have a stabilizer, that was the only thing that would fix it.

Had this DW ever since drove my 09 off from the dealer new. They did a dealer 3" lift and added eccentrics to the lower track bars and adjusted for max caster (bottom of axle housing forward as possible) and still only have 2 degrees pos caster. They have put 2 new shimmy dampeners (higher performance) on only to temporarly help it.
Which track bars do I need to replace with adjustable ones - the top ones going from axle reward to the frame or the lower ones going from the axle housing to the rear frame? I understand I might need to go to as much as 8 degrees + caster.

A double stabilizer works twice as good!

Hey, I'm new to the site! I had a case of the Big DW... Talk about frustrating... It developed progressively and got so bad that it caused my steering box started leaking... ( Yes, I'm a procrastinator) I tightened all the steering components down but found nothing wrong there. Checked the out for loose bearings and it was all tight n' right there. Then I thought maybe the factory track bar was just too much of a sissy to keep up with 36" Tires. Needless to say, I ordered all kinds of parts and the only thing that made it go away was New Tires. If your Running a Bias Tire on your Jeep it's tougher to keep them balanced. I made the switch to a Radial and haven't had a problem since. Putting in 4wd did helped the problem with mine for a temp fix.

Death Wobble on Stock 06 Wrangler

I bought a used 06 Wrangler, all stock except 31x10.5x15 tires on offset rims. Complete with DW. I replaced the trackbar. It had a work bolt and lost of play with only 23K miles. DW was less, but still occurred. I replaced the wheels with stock 30's and stock alloy canyon rims. that changes the speed where DW occured. I changed the the shocks to Bilsteins but still had DW. I replaced a slightly bent, tie rod end. Toe had been set to specs with the bent end. Replacing the end and resetting the toe reduced DW more, but it still occasionally tried. I put on a Ranch steering damper and the DW is gone.

I believe the stock steering damper allows DW, and DW wears the track bar mounts and other suspension components. THen, you have to go through everything. If I were a new Jeep owner, the first thing I would do is put on a heavy duty steering stabalizer. Before DW develops!

Had some serious DW last night, even after I went to bed. Oops, wrong forum. Sorr...(hiccup)y.

Seriously, I had near-DW when I bought my Jeep; right around 50MPH. The tires were fried; don't think they were rotated regularly. Anywho, new ones killed those shakes, but I still have a little, bitty shimmy, as I get off the line, then it smoothes out. Almost feels like a shaft problem or something (though, I'd expect something like that to get worse with increased RPM's). Who knows. Maybe inherent with a SWB vehicle.

Hoping this is another problem I don't get with my Jeep.

Not at all, even big full size trucks from the Big 3 can get DW.

It is specific to rigid front axle trucks/Jeeps. I have personally seen the DW on a LWB Range Rover this winter.

If there's still a problem, it's time to have alignment checked. Most shops will check it for free and give you a readout of the condition. It's usually about $60-$70 to get the alignment done if it's not in spec

I had a death wobble problem when I got my TJ last spring. I first noticed it when I had my friends 3 kids in the Jeep taking them for a ride. When we got back onto the tar road. I got up to 50mph and it jumped the crap out of me. I pulled over and checked a few things and then drove off. it came back a couple days later. For some reason I jerked the wheel and it went away. It happened 2 or 3 more times and I stopped driving it for a week. In that time I changed shocks, checked bushing and changed u joints. That did nothing. The last thing I changed was the front Track bar bushing. The one I didnt check it was there was no sleeve left inside and the mounting bracked holes were slopped out. I over sized the holes to 1/2", installed a new bushing and made a new sleeve because the one that came with the bushing kit was to small. The wobble is gone.

Now to cut off the front fenders and make some custom flat fenders.

OK... I bought a used 04 wrangler last summer. I kept seeing these posts about Death wobble and was wondering what you guys were talking about... It is completely stock and only has about 46k miles (I have put 10k on it myself). About a month ago, on the interstate I hit a bad spot in the road... and found out what "death wobble" is. It only happens in my jeep every once in a while... typically between 55-65. However, my wife drove it today... and it got her. She came back wondering what in the heck was wrong with the jeep. I told her what I thought it was... it has only happened to me maybe 3x and only one was bad.

I have this entire post and many of the attachments. Most of you folks are way more mechanically inclined than I am. Is any of this covered under a recall or warranty from Jeep? It just seems that this is way too prevalent for Jeep not to do something about it. I have seen posts out here about other vehicles doing this... I have had a variety of trucks and cars in my life and never had anything like this. I even drove a ford ranger for 7 years... had the engine and transmission replaced twice, went through more mud and over more stumps than I really should remember and NEVER had this kind of thing. By comparison, my jeep has never been off-road... sad but true. I am really concerned about how much money this is going to costs to fix.

I just bought an 06 tj with 27k (still has original wrangler rt/s tires).

I had it three weeks and started to have DW. It was so bad the other day I had to take it back to the dealership. They replaced steering shock, it was busted and spraying liquid. For now, seems to have fixed the problem.

My 06 was the sam at 23 K miles. I had to replace the track bar and steering stabalizer. You should check the track bar where it attaches on the passenger side. Watch the connection while someone moves the steering wheel back and forth. If the connection is loose, the track bar needs to be replaced.

Ours was the track bar bushing. Got rid of most of it. Mechanic recommended new tires to complete the job.

Check the wear on your tires, when my jeep started shaking, I kinda kept going to that same speed because it was fun, probably terrible on my Jeep though. However, it did turn out to be that one tire was absolutely bald and 2 others were in almost bald shape. Replaced the tires and it rides just fine. Go under your Jeep and see if something is leaking or loose, its probably something simple. There is no warranty that will fix this especially since youre past the 3 year/36,000 mark

I'm sure someone has posted this.
There are a number of death wobble videos on youtube


I believe that I'm in the beginning stages of the second coming of the death wobble for my 04 TJ. At around 45 mph there is a slight shaking until about 50 mph.
I did not notice this until I rotated my tires the other day myself.
First time around the dealership replaced my shocks, steering stabilizer and finally the trac bar which is what fixed it. That was about five years ago.

Stupid question because I really don't know:
If you rotate your tires yourself do you have to get them rebalanced?
And could this be the problem?

Unless a tire loses a balancing weight it should not need to be re-balanced. That being said, it is real easy to knock a weight off while off road.

So, I can pretty much count on this happening if I buy a Jeep? Do you consider it to be a normal maintenance thing? Because it does not seem like a normal maintenance item to me. This really makes me have second thoughts about buying a Jeep.
