Wheel bearings are tight. (Tightening them actually made the wobble more violent.)
Ball joints have no obvious play on them.
Struts are koni adjustables.
I put in turbo tie rods a month ago.
Zero Toe
0.5 deg neg camber on the front.
I will be replacing the ball joints (another pelican said that that was his ultimate fix)
Is there anything else I’m missing??
Why would tightening the bearings make the wobble more violent?
I just had the car balanced and aligned a month ago and it was a buttery smooth dream to drive. It has been a slow development for this wobble. It didn’t show up overnight but now it’s bad enough I have to deal with it. I just had the wheels balanced a few days ago and it moved the wobble higher in the speed range to where it is now. (Before it was focused from 55-65 disappearing at 70, now its 65 disappearing at 90)

Had same wobble at speed about 28 years ago. Mine was corrected with new ball joints, old one was pretty weak. How many miles on yours? Mine had about 98 K miles. I just replaced mine again (not needed (20 k on them) but had the front suspension off for bushings so I did the ball joints and packed the wheel bearings).
New ball joints are pretty stiff, if you do yours and the old ones flop, a good chance this at least part of your problem.
