Wheel shimmy from 30-55 mph and light braking NOT rotors, any ideas?

I have searched and found a mixed bag of possibilities. My situation happens on light braking (feels like bad rotors, rotors are fine) and from 30-55 mph, so annoying and getting worse. Thanks in advance.

I had a similar issue a while back. Check the big wishbones up front. I ended up just doing all control arms and ball joints, but I think the wishbones were the main cause

Because I checked them, they are fine, 0 warp. It is a bushing for sure. Ill just redo the whole front end, the Lincoln parts are cheap enough.

I have the same shimmy on acceleration. Solved the shimmy on braking w/ new rotors.

Need to take a close look at front suspension but I'm thinking upper wishbones...
