You can try replacing your control arm bushings.

Is it lifted? Taller tires? What is your caster angle?

Check for play in your pitman arm. Any play in the steering?

If the tires are correctly balanced, it really shouldn't matter how sloppy the steering is.

We have a 3500, 2006 Duramax I drive daily at work. Had play in the steering, perfectly balanced tires, and would get death wobble at the most inopportune times. Usually with 15k lbs behind it, since it's rarely without a gooseneck and bobcat behind it. Finally slid under it while someone rocked the steering wheel back and forth. Had play in the pitman arm at the tie rod. Replaced it, and death wobble gone for two months now. Tire balance has nothing to do with it.

Tire balance has nothing to do with it. Where have I heard that before?
On the other hand, I've driven with the steering completely disconnected without getting any wobble.

This "It's NOT the tires!" mantra cracks me up.

I first saw it in the lengthy vibration thread a few years ago. Despite being told it wouldn't help, many tried getting the tires balanced correctly...and their vibrations disappeared.
Now we're being told that correct balance won't help with death wobble, either. Some got their tires correctly balanced, and once again...it helped.

If nothing else, since unbalanced tires can be so hard on all the front end components that can allow death wobble to occur, why would you not have the best balance possible?

In one case, "tire balance has nothing to do with it" could hold true, especially if the tires are reasonable sized and recently balanced correctly. In another case, tire balance could factor into the list of sloppy tolerances that stack up to death wobble. The fact is that unless you check everything you may not get rid of the issue, but it is indeed possible to weed out possible contributors (notice contributors, not causes) like tire balance by having them adjusted correctly and doing research on the best tires (according to thuren square sidewall tires are the worst for death wobble, better to have a softer, rounded sidewall profile.) As Jimmy said, too, why not get everything else in spec while you're in there and eliminate excessive tire/component wear down the road?

This reminds me of my most recent case of death wobble, on a low mileage (about 15,000) Jeep JK.

It had what looked like perfect tires on it, no wear, nothing odd. But they were from 2008, original to the Jeep, so new ones were installed, and correctly balanced.

Imagine my surprise when one morning it wobbled on me, twice in rapid succession. Best I can tell, it was because it had sat for a month or so, and the flat spotting was all it took. Once the tires were warm the issue was gone.

In that sense even well balanced tires can be the cause. Could some adjustments take care of it? Probably.

What everyone is trying to tell you, by not telling you anything, is you'll need to list everything about your front end. Tire size, amount of play in the joints and bushings, type of tires you're running and all other pertinent information you can come up with. Also, spelling is much appreciated as it helps keep the English department from bashing your homework. Unless you are talking about the Red Baron and a blot of acid, then that's on you.

Death wobble only became so prevalent in the last 15 years because of garbage Chinese made parts that are not greasable.

I didn’t read through all the responses but figured I would just share what the cure was for me. My truck almost drove itself into a highway barrier a couple times. It was bone stock and the front end was like new. If you research it you will see a ton of different “this will fix your death wobble” opinions based on individual experiences. For me, upgrading the steering linkage to the 2009-???? style not only dramatically improved steering and road feel but immediately solved my death wobble problems. I have since installed a 2” leveling kit with 35” tires. I was curious if this would bring the death wobble back. Fortunately it has not tried to wobble once.
This is what worked for me, it might now work for you BUT I highly recommend the upgrade regardless. I consider the improvement in steering as a step in the right direction regarding safety at a minimum.

for stock height trucks, sumo springs or timbrens where the bump stops go. with those installed the DW can never start... in my experience. i have something like 70-80k miles since my sumo install and 150-160k??? miles since going back to new stock type parts and never any hint of DW. i hit an expansion joint on the way to work that for sure would set it off as it really really sucks, but not even a whisper of DW.

i will see if i can find my back to stock steering thread, if i made one and the sumo install for reference and bump the sumo thread...
