Default Death wobble

Guys I'm stumped here. I have been fighting a death wobble situation with my car all year and it's finally undrivable. I have replaced pretty much everything yet it still has progressively gotten worse thru out the year. As of right now I have replaced steering rack. Rack bushings. Inners. Outers. Ball joints. Control arms. Control arm bushings. Tried factory tension rods. Swapped wheels several times. I'm lost. Wheel bearings are tight. I feel like the rack has more play than it should inside but swapping it out made zero change from my last one. The only thing that made any difference at all is wheels but it's only slightly better. If I hit a bump it just goes violently out of control shake.

Any ideas would he great.

I'm assuming you're not running P/S right?

I've never heard of death-wobble in a car... usually that's reserved for lifted trucks and usually because there is so much mass in the tires and slack in the system that it can't naturally dampen vibrations.

I've always managed to fix it in trucks with either tire balance, ball joints or alignment.

usually crappy tension rods or poor alignment are what make the front end feel sketchy on 240s I've owned/driven... it could also be a blown strut.

I do have power steering.

I know. Lol. It is exactly the same as jeep death wobble. Hit a bump. Pot hole. Or sewer cover and it the front wheels go out of control shaking. Feels like I'm swearving the steering wheel back and forth as fast and as hard as I can until I slam on the brakes and get it down to like 10-20 mph. Alignment has been a couple different ways with toe. Granted it's just a string and tape measure alignment. It has been for year tho. I swapped stock tension rods in yesterday and zero change. Swapping wheels didn't change much either. I could see if maybe I could borrow a coil over from someone and try them. Mine aren't leaking but they are getting older. Idk. I can't figure it out

yeah, the strut is the only thing left I can think of that you haven't replaced that might have any effect on steering.

When you swapped the rack did you put in a new one or another used one?

Also, are you running a front sway-bar?

I will try adjusting my dampening and seeing it makes any difference. I'll try and find a set of front coil overs I can try too.

The rack is from ursins car. It's less than a year old and he bought it new.

I have a silky front sway bar.

I have solid motor mounts.

The steering is very tight from side to side.

I put on a set of known good set of springs and struts on it today and it made zero difference. I guess my next option is to try a known good set of wheels and tires. These Hoosiers haven't bern used in a while so it's hard to know if they are perfect. I'm gonna steal my mothers mustang wheels.
