Another Frustrated Jeeper - DW

I hate to put out ANOTHER death wobble thread, but in my research I've come up empty handed. Here's a little back ground: After the 3.5 IRO lift and front adj. tracbar was installed on my 95 I6, everything was peachy. After about eight weeks, I installed an adj. rear tracbar, and there came a 'floating' sensation, that made it feel like the body was separate from the axles. I replaced the ball joints and all became well. After three months of rolling strong, I experienced DW for the first time... on stock tires. I only got it whenever I hit a bump at 35 mph or greater. I got an alignment, problem went away for a day. Upon its return the next day, I replaced the TRE's, checked the ball joints and all of the front end bushings, and installed a new OME ss (I realize it doesn't do much, but I did it for kicks and giggles). I got an alignment today after replacing my TRE's, and the 'floating' sensation is back, as well as more severe DW that comes up just from reaching a speed of 40 mph or higher. Are my ball joints bad after just a couple of months? I've checked the torque on the tracbars, ball joints, TRE's, and ss.

Anyone have any ideas? Thanks in advance.

When you replaced your ball joints and tre's, what brand did you go with? And you said you checked your control arm bushings? What front track bar did you go with?

Let's start with the basics.
How worn are the tires?
Ball joint brand?
Dry steering test?
Before and after alignment numbers?

I have the IRO heavy duty adjustable trackbar with bracket up front, and the IRO heavy duty double shear adjustable trackbar in the rear. The TRE's are NAPA chassis brand, and the ball joints are Duralast, I beleive; although, it's been a while so I'm not 100% on that.

Forgive my adolescence, I'm still relatively new to this, but I don't know what a dry steering test would be. The tires are easily still at 60%, they're 30" Wildcat A/T's.

Camber:

Front Right: Actual -0.1 Before -0.1
Front Left: Actual -0.5 Before -0.5

Toe:

Right: Actual 0.03 Before -0.81
Left: Actual 0.05 Before 2.85

Front:

Total Toe Actual 0.08
Cross Camber Actual -0.4

try rotating your tires see if it makes a difference mine had a seperated belt in the right front tire and rotating the tires solved the problem had to buy a couple tires ( scared the s*** out of the wife when it happened with her in the ZJ). Hope this helps

the floating sensation you had sounds similar to something i had when i first put my adj track bar on. it turned out that the nut on the track bar that you tighten to keep it from rotating wasnt really F'n tight

you didnt say anything about the sway bar links are they still hooked up also the tack bar not correctly adjusted could also be the problem but the best thing i did was change out the control arms never had a problem after that the stock ones are really weak and the bushings may look ok but the stock arms flex really bad imy zj is lifted 5.5 inches and i have no problems at all i drive mine daily

Thanks for the tip, I did find the rear to be only finger tight. After cranking them down I took her for a test drive but, no dice. Still floating.

I have extended links in the rear and JKS quicker discos up front; all of which nice and solid. The trackbar (to my best guess) look pretty dead on. I have IRO heavy duty adjustable CA's that I'll be installing along with new bushings tomorrow. I'm hoping worn CA bushings is all it is. Thanks for the help.

Are the control arm bushings original? If they are that's defiantly the problem.
