Front End Floats

That would be camber change with the falling LCA, And the camber change sucked the toe pattern outta whack, When the toe goes,squirrely comes.
This is sometimes called bump-steer, but in your case is actually a toe-pattern issue.
It took me about a day to pattern it on my S, and fix it. I was working as an alignment tech at the time, and had unlimited after-hour use of the rack, so it cost me just time.
The offset UCA bushings make it worse, but the extra caster is so worth it. Ride height also monkeys with it.
It is better to have large diameter tires on the front, and level LCAs, than to have small diameter tires and a jacked up LCA. This is for straightline action.
A street alignment would be a lil different, cuz there's a lot of turning involved.
With turning and body-roll, different again.
You can have one alignment sorta do it all, sorta, but that toe-pattern has to be optimized.
Bad LCA bushings will make it worse too. Strut bushings not so much,unless one is good and the other is bad.
If you have alignment gauges you can map this in your garage. But it will be tough,for sure. It is waaay easier on the alignment rack, where you can instantly see toe changes.
