Toe-in changes when front end lifts at track

OK, I'm Probably way out there in left field. I had a B body do the same thing. But, possibly, I misread this, as I'm sicker than heck right now. As I jacked up the Passenger side, I'd see the tire move, bout 3/4 or more, sliding aside jacked it up, and as it left the ground. It was a bad idler arm causing it. Under load the tire did what it was supposed to, as the suspension unloaded, the tire slid laterally..... but no, I Ain't no Mechanic, you can axe RustyRatRod, I have to ask him what a 1/2" ratchet is for everyday

Something like that would be the only way I could see that much movement not making the car completely undrivable, it would have to be a response specifically to being fully unloaded. Because if it always had that much toe change the steering would be all over the place and the tire wear would be ridiculous.
