2010 jku bump steer and death wobble

It first Happened like 5 months ago and my tires were worn out so I got new tires it did it even worse re torqued all the steering track bar and drag link the drag link and track bar are mounted in stock locations but are aftermarket I only have approx . 4in of lift or so , on coilovers and bypass front and rear . I have since put brand new tie rod end ball joints , track bars front and rear and new drag link . It still does it I'm think the steering box is worn out there is a lot of slop in the steering wheel , I have put on new tires still does it currently on 39" Baja claw ttc . Thinking of going hydro assist to hopefully fix this dam thing.
If anyone can help me out I would really appreciate it? Could it be control arm bushings ? Bent axle c's ? Axle u joints ?

Most likely your bump steer is caused by the trackbar/drag link not being parallel. Mine was horrible when I bought my Jeep. Ended up building a new drag link, and flipping it to the bottom of the high steer arm. Now it drives like my F150.

Here is an example pic to go by.

Figured it out ! the hole on the knuckle side of the drag link was ovaled out so I drilled knuckle to 7/8. Installed a new 7/8 fk teflon heim w/ .50" 7/8 cone spacers, I also flipped the drag link to the top of the knuckle. I installed a synergy front & rear raised track bar mounts . They look perfectly parallel now and the jeep drives a million times better. Now I Need to play with the rear coilovers ????? Getting rid of the hardtop & rear bumper & spare tire made it way to stiff .
