Is this the dreaded death wobble?

I've read about it a lot. I'm not sure if it's the DW though. I own a stock 06 unlifted and doesn't have any mods. First it was slight shakes around 50-55 mph, if I accelerate through it goes away.
But just today if I cruise at 50-55 the shake escalates quickly leading to violent shaking of the front end for about 3-5 seconds until I let off the gas pedal and drop below 50 mph. However, if I accelerate from 0 up to 100 mph smoothly I never get the violent shake. It's only if I stay at the 50-55 mph mark. Above or below its all fine.

Any thoughts?

Sounds like a tire out of balance

I had the tired balanced and had alignment done 2 days ago. My tired are worn out though. Also I never had this problem before I did the tire balance. Did it get messed up after the balance maybe?

Usually speed related wobble like that is due to your tires, they could also be outta round.

True death wobble can happen at almost any speed and is usually due to a bump in the road cycling the suspension. This is often due to worn out bushings on your CA's or trackbar and also your camber being out

I just recently experienced the same thing. I had my wife rock the steering wheel back and forth while checked all my tie rid ends and track bar. Come to find out my track bar bushing is bad it wasn't moving a lot but it was shifting from side to side. I do think having you tires rebalanced wouldn't hurt but for sure check your track bar bushing.

He said his tires are worn out so I bet they are out of round too

When mine DW'd, I was driving 60 down a washboard rough section of interstate when all of the sudden it started shaking so bad I couldn't see clearly, and it didn't stop until i was stopped on the shoulder of the road. I literally looked in the mirror for pieces, i thought I might see my front axle laying on the road. Teeth rattling shaking. Violent shaking. White knuckle grip on the steering wheel because its trying to tear out of your hands shaking. Did it 3x, fortunately the road was smooth on the rest of the trip.

I checked my front end out, and found the tie rod end on the track bar was loose - probably a lot looser from the DW experience. 95 degree day, old tires.

I replaced the track bar, steering damper, replaced the tires, and had my jeep aligned. Night and day difference, hasn't happened since, but I am never relaxed while driving it now.

Check your front steering components, check your tire pressure- -possibly the shop aired them up too much?

Good example in the first paragraph

Mine has had it 3x also once coming off a bridge and twice going over the local dam due to the expansion joints

I have seen worn and cupped tires cause that. Since you need to replace the tires anyway, do that first and get an alignment, then see if the issue is resolved.

Replace the tires, if that doesnt fix it then its most likely a bushing worn out

Lots of things may cause DW. If it scared you and everyone to the point of having to change your pants then it most likely is DW. I had mine between 50-55. There are many reasons for DW. Mine was tires out of balance and a worn track bar. Do not drink the Kool-aid and just get a new steering stabilizer as it masks the problem and does not fix it.

My TJ is susceptible to DW when tires are worn and/or out of balance. Just a couple of weeks ago, I threw a wheel weight which caused DW to return.

Since your issue began suddenly, your worn tires along with their rotation (which probably happened during balancing) is a likely culprit.

I would fix it before driving it for any duration. After three death wobble occurances I had a broken steering column and who knows what else - just from the force of the shaking.

Thanks for all of your inputs people. I have checked most front end components and it's all tight and good. My only bet now are tires. Hopefully that'll fix that road demon.

I'll let you guys know if tires fixed the problem; that'll be until I get new tires (broke college student)

Regards!

Right, so I know this an old thread but just wanted to let everyone know that after 2 months of saving up, I finally got new tires
And voila! Death wobble's gone
I'm so glad I can drive it at speed or 80 mph again
Though there will always be that tiny fear that the demon might show up out of nowhere.
Not anytime soon I hope.
So yes, people of your DW is speed dependent, change your tires!

Regards!
