Death Wobble Problems

You don't give enough info to be very specific. What kind of Jeep do you drive? Is it lifted? How many miles? Is the steering all stock?

You are suffering from many of the symptoms common with DW. It often shows up after having new or balanced tires and/or an alignment done.

If your lift (if you have one) is 4" or more, ask the alignment shop what the caster they are setting it at. A TJ will call for +7 degrees in the specs. With the lift, you need to drop back to 2.5 or 3.0 degrees. That will often help if all the other joints are in top shape.

Otherwise, take another read of my first post on this subject for more help.
I have more than a little experience with this on several Jeeps.

Good luck.

Dw

I have a 2004 stock TJ Sport with 49k. I only have time to offroad a couple times a month and I take it pretty easy on the Jeep roads. I have 31" BFG AT's and a Rancho SS. I have no lift and the original shocks. I had this problem two years ago with 24k after I had the stock GY Wrangler tires rotated; the problem disappeared after I had the new BFG AT tires and Rancho steering stabilizer installed and the alignment done. It recently occurred after I had the alignment done and the tires rotated. Yesterday, I took it back to the shop and they supposedly rebalanced the tires. The mechanic who did the work told me that the track bar, tie rod end and drag link needed to be replaced. Today, the DW was worse after I drove over a section with a few minor bumps in the road. I'm going to take it back and have them check the balancing and rotate the tires again. I should have them check the alignment again too. The alignment is guaranteed for a year. There are only a couple of alignment shops here where I live. Any light that you can shed on my DW would be appreciated. I read your other post, but I'll read it again. Thank you.

Death Wobble

For those of you with lifted Wranglers suffering from the Death Wobble, let me make a suggestion. Go to this web address and watch all 3 of the videos on aligning a TJ with a Teraflex lift. I know that it may not be exactly what you have for a suspension, but some of the "rules" still apply.
Pay particular attention to when he tells about setting the caster. This is where too many alignment shops drop the ball. They try to set you up according to the factory specs. Factory specs no longer apply to you when you start lifting a Jeep.
Give it a look. I can practically guarantee you will learn something.

Be sure to watch all three to get the whole education.

Any suggestions for non-lifted TJ's?

Mine is stock, with the exception of the 31's and Rancho SS. Any suggestions? Thanks.

Its Back

So I thought I had gotten rid of the wobble in my 06 Unl. Rubi, and about a month ago it started coming back. Its not as severe but it definitely wants to do it between 45 and 50. I upgraded the stabilizer, put on an adjustable track bar and had the tires balanced and an alignment done at 4wheel parts. At this point they just want to add another stabilizer but I don't think that is the answer. I've got a 2.5 inch EMU lift on it, if anyone has anything else to try I am all ears. Thanks.

wobble

The first time you cured the wobble you rotated the tires, bum tire maybe was the cause.New tires, no wobble for 25,000 miles.That is alot of miles on a radial tire without rotation,possible cupping starting. Now,new parts in front end and alignment.Did you get a print out of the alignment figures? If the tech set the caster to factory specs he may have to lower it a tad. factory spec is about 7 degrees +/- 1, I set caster about 4.5 degrees +/- 1 and have no problems. I have aligned cars to semi trucks for the last 30 years.

I rotated the tires every 5000 miles with each oil change. However, maybe they never rotated them like they said. I took the Jeep to another mechanic and he told me that the toe in was off. He said that the track bar, tie rod, TRE, and drag link were fine. I went back to the shop where I had the alignment done, and that is where the Jeep is as I write this post. I'll call him and ask him about the figures. Thank you for the help.

Death Wobble Problems

As you have a basically stock rig, the mileage and description of what you have done lead me to believe that the alignment shop you are taking it to isn't experienced with this problem. If you are really patient they may learn, but it will be just hit and miss and luck.
I agree with the other post that you may want to reduce the caster... but I don't think on a stock rig I would go down to +4 degrees. I think +5 would be more appropriate. Doing this might cure the problem for a while, but will only hide the real one.
Have the alignment shop do a check of all the steering rod ends and the control arm joints to see if they show any wear at all. With the mileage you have, I'm betting there will be some.
**One other thing to check is that the frame end of the track bar is stable. If the frame is flexing or the track bar tower is able to move, that will cause the DW.
Also check to see that the steering gear is not loose or flexing on the frame.
Have them really check the track bar ends closely... they are a large contributor to DW.

If they only find "normal wear", start by replacing the track bar first.

If that is not enough, replace the ball joints. Next would be the control arms (you should be able to pick up some used ones from a 4x4 shop that has done a lift for someone pretty cheap).

The last things to replace would be the tie rod and drag link ends.

I wish you well and Happy Trails.

wobble

2011 Dodge 2500 HD 4x4 with 5011 miles in the shop today.2" leveling kit installed,no problems before the kit. Wobble in the front end after the kit was installed when bumps were hit on the highway.Factory caster spec 4.5 degrees +/- .5 positive ,including frame angle after leveling kit caster was 6.7 degrees positive. Caster was changed to 3.0 degrees,including frame angle total caster 4.0 degrees positive. No more death wobble,no more problems and nobody spent $ on parts that won't solve the problem.This was a brand new truck, no worn parts,no bad tires, no problems until the leveling kit was installed and the caster went over 5.0 degrees positive, almost 2.0 degrees over.Once tires and front suspension parts are inspected and deemed good, a good alignment tech should be found that has experience with Death Wobble and adjusting caster to help handling.

Thank you for the tips. I went to another mechanic who said that the front end was fine, and then I went to the shop that did the alignment. The mechanic showed me where there was play in the track bar, TRE, and drag link; he also showed me that the bushing in the control arms are wearing out, especially the lower control arms. I had them put the read tires back in front. I can see that there is play in the suspension, but I think that the rotation of the tires caused the DW. The mechanic said that the worn suspension was cupping the tires and that BFG AT's were more prone to cupping. I think that I'm going to start with a Moog track bar and maybe a Crown Heavy Duty Steering Kit for now. I'm going to have to get some new tires pretty soon, but I'm going to try to get as many miles out of these tires as they only have 24K and I can't afford a new set just now. Tomorrow, I drive it more and see it the rotation helped. Thanks again for all who have shared there experience and expertise. Have a good one!

I had the shop rebalance and rotate the tires. I drove 140 miles yesterday and no DW. However, the Jeep does drift to the right. I'm going to take it back after I install a new track bar and Crown Heavy Duty Steering Kit. I might have the control arm bushing replaced as well. Thanks again guys for the help.

2x Jeep owner. Paid off my '08 Wrangler Unlimited two months ago but am very concerned about this Death Wobble. Bought the lifetime bumper to bumper with the full intent of handing this car down to our 4 kids. Oldest will be driving in 3 years. Everything is still factory on the car. Multiple experiences of DW at about 20,000 miles and again at 36,200. Dealer replaced the steering dampener. Chrysler refunded associated expenses, but refused to acknowledge an issue; they instead deemed the refund "good will."

Reading through posts below, I see some say it "gets better" with various fixes. How do you define "better"? DW nearly rips the steering wheel out of your hands, at high speeds no less. I think you either have it or you don't.

I do not panic when I get DW and honestly believe that I can bring the Jeep back under control. But I cannot fathom giving this to a 16 year old. I might as well buy them a coffin.

Personally, I opted for filing a complaint with the NHTSA, (888) 327-4236, https://www-odi.nhtsa.dot.gov/ivoq/.

Is this an inherent design flaw? Why hasn't there been a recall? Is it because the fix isn't straight forward?

The stabiliser is obviously there for a purpose as part of the overall design, and the fact is replacing that failed part was the solution to stop DW on my jeep regardless of any other involved analysis you want to get involved in.

For me I would rather see posts offering solutions that have worked for others than posts that maybe just put others off from posting their own experiences.

So come on guys, I would like to know if this is an issue which maybe affects more 2003 wranglers than earlier ones, as I seem to have seen more posts from owners of 2003 owners than any others.

Also, I note sticking it into 4wd helps when it happens, however I find on my 2003 Sahara it won't engage 4wd at anything like the speed that DW occurs, so is there some limiter that only allows 4wd to engage at low speeds on a 2003?... or is that something else I need to fix?

Thanks Dave
I am going to have to agree with Mr. Bransford. You are not "hearing" what he's telling you. The stabilizer only MASKS your problem... for a while. It will come back on you. I will agree that the article he points out is a lot of "engineer speak" that explains the dynamics well, but that has to be understood properly to be of any value.
Try reading Death Wobble
In it, I don't dwell on the engineering, but the causes and some of the cures. This is not an "easy fix" problem normally. This article doesn't place blame on tires out of balance... they can be the pressure on the trigger, but they are not what allows DW to occur. They just aggravate the problem.
"Listen" to some of the answers here. (not all of them... most are just remembering what they have heard) The experienced ones stand out to me. But then, I've worked on several with DW that other "good" shops couldn't cure --- with success. (no brag, just fact!)
DW is a beast, for the owner and for the mechanic. Most owners think the mechanic is a rip-off artist before it's done. Experience and an excellent understanding of suspensions and alignments are the best answer to your problem. All those moving parts require an art to understand when dealing with the DW. Happy Trails!

You are wise to not want a new driver having to deal with DW. There are many things you don't want to experience and DW is right at the top of the list.
The Jeep dealer mechanics "should" know that the damper is only hiding the real problem... but they are under the gun to "just get it out the door" by any cheap method they can. Actually, an excellent alignment shop (not usually one of the chain shops) can be of more help than most. If you know a 4x4 shop with way better than most techs/ mechanics, they will have a better than good idea of what to look for. Especially if the Jeep is lifted. Lifted rigs require some know how that stock rigs do not.
My experience with JKs like yours makes me suspect that the ball joints are sufficiently worn to be at least where I would have the shop look.
The JK seems to be showing a problem in that area. Don't take this to mean this IS YOUR problem for sure, just a good starting place.
You don't state whether or not you have larger tires than stock. Larger tires will create an added load on things like ball joints.
If the dealer won't/ can't repair it on their own, take it to a good alignment shop and ask them to "really" check all the Joints--- ball joints, tie rod ends, drag link ends, track bar ends, control arm ends, and flex in the track bar tower on the frame end, and flex in the steering gear or frame in that area. Tell them to note ANY wear in all of those possibilities. A little here and a little there add up to a lot where your front suspension is concerned.
As for this being a design flaw, I wouldn't exactly call it that, but it's not far off. This has been around for 40 years that I know of and suspect it started way before that. It can be repaired, but it may take some time to find all of the problems. They hide well because it's seldom one big thing causing the whole thing. For more info, read my article at:

The fixes are straight forward. DW is fairly simple to diagnose and correct.

There is somewhat of a design flaw on JKs in that Chrysler decided to use a 14mm trackbar bolt in a trackbar bushing sleeve that fits a 9/16" bolt, and with bracket holes that are 15-16mm large.

Because the bracket bolt holes are too large for the bolts, the up to 2 mm of play allows the bolt to violently cycle/resonate back and forth in the bracket holes when the bolts are not sufficiently torqued--elongating the holes and making the situation even worse.

The trackbar bolts need to be torqued to 125 ft lbs. Any loosening of the bolts through normal cycling of the suspension and lack of proper maintenance will result in DW.

The other issue is that re-torquing the front JK trackbar bolts to 125 ft lbs should be done at every oil change interval (3-5 times a year), and after every major offroading trip. This must be part of the regular scheduled maintenance, part of the owners' manual, and trained to Chrysler techs.

Since you have had more than one instance of DW, and instead of simply fixing it, the dealer installed a new steering stabilizer that eventually failed because it could not mask the source any longer, the DW likely has damaged several other front end components.

Given that you have a JK, it would help if you read this:

My '04 Jeep Wrangler Sport 4.0 5sp,with 9600 actual miles just started the DW ! WOW! This scared me!! I am a Parts Mgr at Janzen Toyota in Stillwater,OK. I had our best front end tech look at this. Here is what we did. The original 30x9.50r15 were DOT dated to the 14 week of 2004. They were cupped and choppy on the front 2 tires with around 6/32 tread left on the front & 8/32 on the back. We did a front end alignment & found the caster was way off to the -. Then greased every zerk we could find. Installed a Old Man Emu steering stabilizer, mounted new 31x10.50r15 Goodyear Wrangler Silent Armour LTC set to 30psi, on a set of Ballastic Flash Wheels. Roadforced wheels & tires to get a better balance. WOW!!! after 3k, ** Absolutely NO Death Wobble **

You also want to remove the trackbar to inspect the bracket holes for ovaling and the bushings for wear.

You also want to inspect the ball joints for up and down movement of the lowers and lateral movement of the uppers.

You also want to inspect the tie rod and drag link ends for wear.

DW is usually but not always trackbar related. However, it can be triggered by other sources--i.e. bad tires, bad alignment, etc.

Even one instance of DW can damage other components--ball joints, joint ends, trackbar bracket holes and welds, etc.

Unless the actual source of the DW has been fixed, it will resurface in the future when the new steering stabilizer can no longer mask the source. This may take a while with newer tires that have less of a tendency to trigger it.

However, one of these times in the future, you will hit a pothole or railroad track in the wrong way and it will trigger DW again if the source(s) are not fixed.

So I put on a 2.5 Rough Country lift and had no problem....two days later had new 33 duratracs put on and now have DW at 45-50mph? I even had a new steering stabalizer put on with the lift. HELP

Death Wobble Problems

Your info is a little lacking to be very specific.
1. After the lift, did you drive it? If so, on the same roads and same speeds that the DW showed up after the tires?
2. Are the tires of the same size as before or did the lift allow for larger tires?
3. After the lift, did you have it aligned?

If no on #3, have that looked after first--- with the items in post 193 here checked out. The the alignment tech what you have done and what you are experiencing.
You might want a copy of post 193 and one of Death Wobble to take along for the tech to study.
They are going to want to know about checking all link ends and ball joints VERRRRRY carefully. Anything they miss could be the problem or atleast part of the problem. DW is seldom just on thing. If it is, it will stand out.

Be sure the alignment tech follows the Caster changes recommended, otherwise, all bets are off.

death wobble

i just fixed my death wobble today. i always ck the track bar first and it was loose at the frame. thats the second time and second fix at the track bar. the stabilizer shock will cover up wobble for a short time but is seldom the cause of the problem. c-ya.

We have an 06 Unlimited that had Death Wobble. It started after we installed a 2" BB. During our investigation, the first actual problem we found was a damaged RF tie rod. We replaced that, the steering stabilizer, the trac bar (put on a Currie adjustable), new tires, new rims, adjustable cam bolts, yada, yada yada. It finally went away when we put on ADJUSTABLE LOWER CONTROL ARMS. I don't know if this will fix yours, but we've gone over every spot that ever caused ours at varying speeds from 20-90 mph(not recommended) and it's gone!! We now run that 2" BB on 265/75/17's and no problems. Knock on wood. And yes, Jerry Bransford is deifnitely a fountain of knowledge. Thanks for helping out everyone Jerry.

How or what did the adjustable lower control arms do to change your Jeep to remove the Death Wobble? If we know how it changed your Jeep we also can figure out what caused the wobble. And if we figure out what caused the wobble we can prevent it from starting in other people's Jeeps when a 2" lift is installed.And that my friend is half the battle,knowing what caused the wobble.

I'm not sure if I had the death wobble or not, so I thought I'd ask. It ONLY shakes when driving about 50-55 mph. It's smooth as can be above or below that speed and has never done the DW except for in that speed range. It's an 01 TJ that's stock on 31's. I feel the steering wheel shake and it shakes the whole jeep, not enough to lose control, but it's annoying to say the least and not very comfortable. I'm going to check the front end for loose components when I get a chance, but I figured I'd get some feedback. I know it's been doing this for a long time now, and it has had several alignments and tires balanced/rotated trying to fix the problem.

How do i know if its a death wobble??

Hi all,

I just bought a 2003 sahara and i find that it wobbles while driving. I at first thought that was just a regular wobble, which leads me to my first question. Does the wrangler wobble normally, especially when going over bumps in the road?

Now at least twice while driving the front end just started to shake/rattle violently. I was about to pull over when it just suddenly stopped. Does this sound like the death wobble to you guys?

Can anyone reccomend a good repair shop in Los Angeles (west side, if possible) that really knows wranglers, that can check it out at a reasonable price?

Final question, i am currently on 30x9.5 tires, psi at 34. Are there larger/wider tires that would help it to feel more stable on the road and less wobbly?

Thanks all.

I love it and am happy to finally be a jeep girl, but I want to nip any issues in the bud before they get much bigger.
