I've been trying to read all the info on the dreaded Death Wobble to try and solve my problem.

I just recently realized, when I have the 33x12.5's on, no DW.
I'm running 215/75/15's on it right now to save $$ so I don't wear out my 33's so fast + for daily driving, and I get DW when I hit a RR track or dip at speed (35-45mph).

Would it be just because of the wider, heavier tire that it doesn't wobble (or it's a lot less and I don't notice) ?

Or could there be some geometry involved with the taller tires and alignment/suspension position ?

I know that my steering stabilizer leaked and is probably not 100%, but I have not gotten a torque wrench on any of the suspension yet to check for any looseness.

chech your alignment / ball joints

if they are ok, i would look at an unbalanced wheel / tire on the 215s

Had a trusted mechanic/tire/alignment shop do these things, after I had the new front tires put on mounted&balanced at another shop.

Most of the time deathwobble is caused by a track bar. then move to tie rods, and bearings. if tires are making it happen it most likley out of balance tires casuing the trouble.

with my last set of tires I had a slight case of DW but I wouldn't say it was DW because it was nothing to bad like the Comanche was when I lifted it
ever since I put my new tires on that slight shake is gone
now if you do have DW does the jeep shake so bad that it feels like the hole thing is falling apart and you have to practically stop before it goes away if so then you have DW and you're steering geometry is not right (to high of an angle normally)
or you have some worn out parts
but since you only have it with those tires on I would say its the tires

All things being equal and when you are running one set you get DW at the same place and then not with the others. I'd say that the one set isn't truly balanced and the other is.

Yeah, I know Nick. I was in his Bronco that day and I was one of the guys helping to push it back on its feet.

My description of it would be that it feels like my front axle came loose and is going to fall off, or my front wheels are going to fall off. Like as if the wheels were only on with one lug and that was loose. If I slow down immediately, it evens out and goes away.

It may be that I didn't have the 33's on long enough to run into the situation where DW occurs.

So you're saying if I have DW, then it's likely that no matter what tire I have on it'll happen the same ?

I think I'll try switching the front and rear tires/wheels. They're different brands, I'll see if it still acts the same.

how much lift do you have
check all the joints especially track bar
and put a new steering stabilizer on since it was leaking
you probably have a bad track bar joint but I would check both your tie rod ends and drag link ends and replace
or your steering is to steep of an angle


normally your track bar has a bad end it will let the axle shift under the rig

No, what I'm thinking is that if you are getting the DW with one set of tires and not the other then I would start with the tires that do cause it.

However that being said. You still need to check the front suspension points that Mr 4x4 told you about. Because if you have had the wobble then odds are somethings have loosened up.

I guess I am going to go against the grain of what everyone is saying.

REGARDLESS of what tire you have on you shouldn't have death wobble. Unbalanced tires result in a shimmy in the steering wheel or quirky steering. Not death wobble. It has been my experience that with larger tires you normally run a smaller air pressure which allows more cushion. Might be enough to keep the death wobble at bay.

You have some other problem other than unbalanced tires. It is not your steering stabilizer. IT IS NOT your steering stabilizer.

You need to get under your jeep and see what is moving. Have someone work the steering wheel back and forth while the jeep is off. You will see the problem. :)

Mostly you guys are saying the same thing. Something is loose in my steering components.

Now I just need to enlist the aid of a co-pilot to work the steering wheel while I check on things. I'm sure my 11 year old will jump at that chance, I already told him the Jeep is his in 5 years.....




And, thanks for all the input, I'm GONNA fix this.

Oooh ok i was in the silver TJ. Tell Nick we gotta get back out again. this time take your jeep too
Were you the dude with no doors and your sways duct taped ? I only remember the black Jeep who was leading, I can't remember how many others there were or what color. Aging brain. That was before I had a Jeep, or knew the difference between a YJ or TJ or CJ.

Yeah, now that I have a Jeep, I just need to make time to go with you guys again. I was going on that Gorman trip before the fires ruined it.

I'm trying to get out to Death Valley, soon. Too bad there's no long weekends between now and Memorial day, I'll have to make one.

How many?

How many different sizes are you running? Or are they just different brands? Before I tried any other moves I would put the 33's in the same situation and try to make the DW occur.

I had DW off and on until I put on dual steering stabilizers. Whether or not it's coincidence, I don't know - but I haven't had it since. . . 05 TJ, 33" procomp xt's, 3 1/2" rubi lift.
