several problems since my re 4.5 lift install

mainly the death wooble. it was undriveable until i had it aligned, now the dw happens when i hit big bumps, usually always on an incline with a curve like a freeway ramp. what can i do. i checked to see if my control arms are tight and i can slightly turn the upper passenger with my hand. it seems like i cant get it tight enough, i assume the bushing is bad but it looks ok. how would i even replace that one since its on the axel? and i noticed this today, could this be the cause?

if there is anyone here close to jonesboro, ar that could look and maybe help me please pm me

Bad ball joints can cause that. Also a loose front track bar, and out of balance wheels, will cause it

One trick I use in troubleshooting front end problems, is to have a friend turn the steering wheel back and forth about 1/8 to a 1/4 turn. While they are doing this inspect the steering for abnormal movement like the track bar, steeing linkage, etc..

I think you are right. There is no ONE thing that will cause DW. I say this because a lot of people blame only a loose track bar. Now I know a lot of you are going to call this BS but. I travelled 8 miles without a front or rear track bar in a friend's newly lifted ZJ.
With NO DW.
I must admit it was quite a task. I had to turn the steering wheel a full turn before the Jeep started turning.
This Jeep had a DW before we installed the lift. The kit was a RE 3.5 lift. I suspect that the lower CA's rubber bushings were shot. The DW only occured when bracking in a turn.

Now for the reason why I travelled without the Track bars. We had an alignment shop install the lift but the rear track bar bracket and the front track bar was for a LHD Jeep. I had no choice but to drive it back to our workshop and do some fabbing work.

You should look at each component sepperately one at a time. A lift just amplifies any dormant problems.
As for the upper control arm rubber. Currie manufactures a Johhny Joint weld on replacement.

I want mine replaced with that as well.

I won't call BS on that. My 87xj front track bar ball joint thing is so worn out it is about to fall off. I can tell it is bad because we watched it while someone turned the wheel back and forth and I can feel it sort of kick over to one side or the other as I turn but even with a 3" lift (homemade and crappy) with 32's (used and crappy) I have NO DW. My tires are balanced and we aligned it with a tape measure. If the trackbar was such a POS for causing DW all the time I would have DW but I don't. I have seen hoes on corners that weren't as loose as my track bar is.
