Re: Bad wobble-'99 TJ (NOT balance related!)
 

there is a big difference in a shimmy and the death wobble.. a shimmy
would be the stabilizer..like Bill said. I am 99.9 % sure it is the tires..
I have had this on numerous Jeeps I have bought through the years and that
has always been a guaranteed fix.

If you buy larger tires, buy a larger steering stabilizer:

Re: Bad wobble-'99 TJ (NOT balance related!)
 

If the CD is skipping and soda is spilling from 4 to 5" side to side,
that's as close to the death wobble you 'ever' want to be....

A worn/about to break part at that point can be deadly.

And no disagreement on tires, I mentioned them as something to look at.

Re: Bad wobble-'99 TJ (NOT balance related!)
 

I have a 99 with a 2" lift and have never fullly gotten rid of the problem. The
track arm is the first suspect. After that i find any part individually or
parts as a group that have play will allow the problem.

I would like to run the stock tires when I am commuting to work. But the DEATH
WOBBLE prevents that. And then I end up replacing the track bar after a coule
of severe incidents. So I keep my 32" MTR's with offset rims on and that
suppresses the problem. I still feel it in the steering wheel trying to come
back. Eventually it will as the pulsations are getting stronger.

The suspension is on the edge to begin with and lifting or adding tires seems
to push it over the edge. If everything is not very tight, a harmonic can begin
and there you have it.

I am going to try replacing the stock control arms. It seems my friends running
with Tera Flex Arms don't have the problem. I am guessing the softer rubber
bushing is allowing to much movement.
