death wobble fix

has anyone toyed around fixing the death wobble?...... i had a guy that gave me some bolts and i replaced the track bar bolts with them....what the hell was jeep thinking putting a completely threaded bolt through a bushing and expecting it to actually last!!!!!! either way they apparently mic'd them out and it showed a .007 difference between the hole and the bolt...either way we have put a shouldered bolt in ours to fix it....i wish i could remember the size we used lol been a while since but seen a post about it.

Those completly threaded bolts are no harm when torqued correctly. But your right, what were they thinking? And yes the replacement bolts of 9/16" with shoulder are an ideal worry less upgrade.

i disagree that it doesnt hurt anything. i used to do mechanic work alot in the oilfield. yes your right in that it needs to be torqued right but on something like that there will always be a slight movement there is no way to completely stop it...its how its designed..otherwise there would be no bushing the just a hole and as the threads move across they will wear down creating an even wider gap and hence wearing more quickly...not trying to offend you its just how they are designed to work.

Your correct, there is always gonna be movement. Thats why there are bushings. When torqued properly, the bolt should never move. Added stress from lifts etc... Can increase chance for failure, however, the bushing is there to absorb slight up and downward movement. No offense taken.

^ that for me only happened when my tires were unbalanced(had water inside the tires)and going over 70+mph, but that video seems to be at low speeds though. Can someone explain why it would do this? Is it because of offroading?

I had the same experience with my tires. Pretty bad but not DW.
DW you have to come to a complete stop to stop it .
It's a harmonic resonance of the axle. Mosh of the time it's track bar related and a number of things - like the tires - can set it off .

Ding ding ding!! Best DW explanation I've seen is right here: (http://www.wranglerforum.com/f33/dia...les-78034.html)

(I know you found it Ltblue, I'm just posting it in case somebody turns this thread up in a search in the future.)

And one of the best vids i have seen. This is the difference between a shimmy and DW.



Notice the havoc is caused on all the front end.
