DEATH WOBBLE?

[kyleup2it]

Sorry Mr Technical you better look again. I had a 99 Ram and encountered Extreme Death Wobble several times, went through a few different suspension/Lift setups and like the tjs and xjs it was a different cause everytime. Tracbar- Its gotta have angle parallel to your pitman arm and draglink, lift with stock control arms is a no no, Caster and Toe have to be On The Money, And Believe it or not even the rear pinion angle can throw the vibration to the front end and start a death wobble as the case with my first lift that involved drop down shackles... I now have an 06 TJ with the IDENTICLE suspension And have yet to correct my death Wobble, Chryler has used this setup on Rams, Xjs, TJs, And ZJs and its theoretically a great design But very touchy... Good Luck Originally Posted by AAA4948 I have a hard time believing that you have death wobble. Last fall when I was up at college, the designers of the new Jeep Wrangler (the JK) came up and gave a seminar on the it. The old TJ's were very prone to death wobble. However, the engineers said they had a fresh new front end that was immune to death wobbling. I recognized it immediately when they showed a cut away: it was the same 4 link + panhard/track bar set up with our trucks. Crawl under and look sumetime and you'll see the similarities. I talked one on one with an engineer about it and they said that it was indeed a copy (or very similar to) the front axles in the BR trucks. I saw the video of the TJ during a death wobble incident on a test video and it looks pretty scary to see the axle moving so violently. I'm not sure what happened with your truck, but from what I was told by Chrysler design engineers (I know come will laugh at this), but they said it was a problem that had been fixed with the new design which is from our trucks. The death wobble is, like others have described, an oscilating rotation of the front axle. This type of motion is restriced in our front ends by the double control arms. As such, in theory, this motion isn't possible unless you have a broken control arm or severley worn control arm bushings. On a side note, the engineer did admit to me that under hard braking, the front ends will tend to steer to the left due to the lateral displacement by the track bar. The track bar would push the axle to the right and the steering components while remaining in a constant position would seem to be steering to the left. But they said this motion would be hard to notice.
