Default Video Evidence

Thanks to vmphoto for pointing out to me that you can see there has been some movement of the bolt on my axle side track bar bracket on picture in my first post. So I went home last night and popped off the track bar to try and determine if the bolt holes had in fact been wallowed or oval'd out.

So here is some video that I took. I don't know if this is definitive evidence, but It looks to me that there is a lot of play in the hole that would suggest this could be the source of the death wobble. Hopefully this video will help others pinpoint their problem and give them a frame of reference.

How many miles are on your lift? Reason I ask is I retorque my suspension compenents every oil change and whether its a control arm or trackbar nut something always needs tightening. have you done this maintenence? If not that could have a hand in your trackbar hole wallowing out over the course of the last 2 years if that bolt has been slowly getting looser over time

I'm glad I could help...
Now I only wish Chrysler would figure out how to fix mine... Same problem except no lift and it is under warrenty... So, they are trying to figure out to fix it with Mopar parts....
I'm optimistic....

I did my lift a little over 2 years ago. I never consistently re-torqued the track bar, but when I did check it, it was torqued to spec. That's what makes this surprising. It would be one thing if I got under there, and it was loose. That would make sense. But as far as I know, it's never not been torqued. I think this just proves that even the smallest amount of movement can lead to death wobble.

It's like planman said: "Chrysler decided to use a 14 mm trackbar bolt, with a trackbar bushing sleeve designed for a 9/16" bolt, and the trackbar bracket bolt holes are somewhere around 15-16 mm large. This is a sure recipe for DW if the trackbar bolts are not properly torqued and periodically re-torqued"

Now I just need to find somebody that can help me with a little welding so I can get this fixed. Hopefully welding on some washers of the appropriate size will solve my problem.

This similar to the problem I am having too. Soon as I changed my tires to 285/70/17 on stock rims I had a wobble/vibration coming from the front end. Today I took it back to the tire shop and they re-checked the tire balance and it was off by .25 on one side and .50 on the other but when the tires were put back on I went for a ride and it still does the same thing. My front end feels like it wobbles or shakes and the steering wheel vibrates when this happens but the rig will still drive perfectly straight. I have 2500 miles on my JK so not sure if anything would be worn out but I am still going to make an appointment to go to the dealer and see what they can find if anything.

I had the DW on my 08 Ram 1500 and they couldn't find anything wrong, so I traded it back to them and bought a wrangler. Happiest day of my life.

I had bad DW, changed out out of round tire, took weights off wheels, put in 15 oz.s of Airsoft bb.s, torqued track bar to 125 ft lb.s (both ends was loose) drag link to 65 ft. lb.s it was loose, torqued tie rod ends to 65lb.s they were loose, re-torqued all arms and lift brackets, and replaced ball joints, replaced Steerin Stab.. DW is gone, jeep never drove better, goes to show it can be an accumilation of many things.

Glad you got it solved

Had my 1st DW a week ago and it occurs only when I get a bump in the street :(

Just got the tires balanced which were out balanced for a long time, will be checking track bar, tie rod and arms later today

I hope I get it solved soon.
