We bought our Jeep last summer from a big local new/used car dealer (Jeep, Ford, Chevy, Honda, Toyota, etc)... It had a bad wobble, but it would go away or you could stop it by slowing down. Never had to stop. So, I didn't consider it "Death Wobble". Normally I would have walked away, but it was in such good shape, engine ran great, it was just what we needed, the price was right and the wife was in love (Plus they threw in a new Kenwood CD player since the stock one didn't work). I figured whatever the problem was it could be fixed with a little time/money/elbow grease. Before we took it home the dealer put two new tires on. That helped a little, then they aligned it. Helped a little more. Then they changed the front rotors/pads and that seemed to help the most. However, right at 70MPH it would still shake. I changed shocked, which were needed, but didn't help the shake, changed the steering stabilizer and that helped a little, changed the front sway bar bushings/endlinks, that helped a little more. New tires a few months back (10,000+ on the other Kumhos) seemed to help a bit too... Finally last weekend I changed the rear sway bar bushings, shackle bushings and leaf springs/bushing (heavy duty stock height). Drove it over a couple hundred miles a few days later at 70+ MPH, smooth as could be. The old springs were shot and almost inverted they were sagging so bad... I plan on doing the tie rod ends, track bar and control arm bushings one of these days. But for now, seems to be running great, and looks better too.
Changing the front rotors and pads on my 01XJ was the most substantial improvement to DW for me as well. It's starting to come back a bit but I suspect the track bar this time. Shocks and stabilizer=zero effect on DW. I'll be due for new tires by December and that shoul help too.

Not having a drop pitman arm won't cause death wobble. It'll cause bump steer. Two different things.

DEATH WOBBLE
I installed a 4.5" RC lift on my 99 XJ a week ago, about a mile away from the shop I got up around 45mph and the jeep got death wobble over a bump...I have to slow down to stop it.i got it aligned... going over like bumps and rail road tracks fine, then it happened again, Everything is tight under the front end, I have brand new lower and upper control arms so buchings cant be the problem. I've read a lot of DW threads on here and I KNOW that no one can pin point my problem JUST from reading my thread, but i'm wondering if I could get some guidance as far as what I should check/replace next. I've read a lot about the trac-bar being a lot of the problem b/c of the angle the lift puts on it compared to how it was factory height. I am running STOCK tires for now they are in balance as far as I can tell from . Please help!!!!!!!!!!!!!!!!!!!!!!!!
