Hi, first time posting here, hope you guys can help. I'm sure this has been discussed before, as i understand wj's are notorious for death wobble. My jeep wj never used to get DW, but over the past year i get these DW's randomly. Usually happens for me around 35-45 mph.
Not sure how else to stop it as it's happening other than just stomping on the brakes. Once I'm back down to around 20 mph it stops. Letting off the gas and coasting doesn't help, it feels like my tires start bouncing off the ground it gets so bad. Luckily it seems to not happen on the highway.
It seems that the trigger for my jeep's DW is at 40 mph, i hit a pothole or even a slight bump in the road, and that jolt is enough to then cause DW. Sometimes i feel a slight wobble in the steering wheel after the bump but then it dissipates, other times it escalates into full blown DW.
My question is, is there any way to solve/eliminate death wobble?
Or, am i stuck worrying about DW at sub-highway speeds?
Any help would be great, or even if u have an older post you could link me.
Well, I replaced a couple parts and now I no longer have death wobble.
My trackbar bushings and steering stabilizer were worn.
I installed the Hard-KOR SUPER-hard Rockwell trackbar bushings and the Hard-KOR Replacement Steering Stabilizer from kevinsoffroad.com.
There is a noticeable difference in the steering, much more responsive and tight steering. Best of all death wobble is 100% gone.
Are you lifted? If so, list the specs and anything you have done to address the issue. There are some common reasons that you can eliminate off the bat. There are actually quite a few of us on this site that have had this issue in the past or are having it now.
Yes, i have 2" coil spacers, longer shocks to go with it and i have slightly larger tires, 265 75R 16's. I have not done anything else. The DW issue did not start when i lifted, it ran just fine for a while. Not to say the lift has nothing to do with it..
Did you touch the Track bar? That is the most common with a lift. Check the bolts to make sure they are as tight as you can make them and then tighten them again. Otherwise, common issues are tie rod ends, worn ball joints and bad hubs. Did you check those out? You can find instructions for testing those on the site. The tie rod ends and then the track bar is probably the issue in most cases.
If you are not sure what this is, turn the steering wheel back and forth rapidly while someone watches underneath. Watch all the steering parts and also any parts responsible for locating the axle. If there is slop somewhere, you will see it.
Do this with the Jeep off and the tires on the ground. Turn the steering wheel from about 9 o'clock to about 3 o'clock. Just enough to induce the slop, but not too much where you cannot saw it back and forth quickly.
So I did the dry steering test and i did not see anything unusual in the steering components, there was no slop anywhere. Any other suggestions would be awesome.
I see the track bar bushing that were linked previously are specifically made to stop death wobble in lifted WJ's. Now, since i didn't notice any unwanted movement in the track bar during my dry steering test, would these bushing indeed help me? Should i replace the stock bushing with these and hope they solve it, or is there a proven fix for this?
I didn't see any play at all in my track at when I did a dry test as well for death wobble, pulled it off though and found the upper rubber bushing deteriorated.
Ordered a new bushing from I want to say Morris 4x4 and DW is gone!
