Adjusting front caster to correct pull/drift...

[meep]

Mike, does it vary with throttle use? My GS tends to “drift” a smidge under hard throttle, and then hold straighter under cruise. I attribute this to bushing flex in the rear.

@Mikey V. How many miles are on your front springs, has it been lowered?

Have you tried a large highway with alternating crowns? Try the far left lane then the far right. What happens on coast, and when applying throttle...any torque steer, worn CV joint?

I suspect the toe was the initial culprit, then how much did it change after the alignment? Your tires might look evenly worn, but put a tread depth gauge on them...they may look even but may be slightly crowned.

What are your tire pressures? Cold air will send them down for sure.

Update!!! The steering pull has been resolved! I had the front tires dismounted, and moved from left to right. The tire swap has taken away the pull and the car now tracks straight with zero pull. The tires are Continental DSW06 from 2018.

Told ya . Conicity is more common than people realize. You just found a happy medium. Glad it was a simple fix.

It sounds to me like you are chasing a problem that isn't there. Any car will drift one way or the other if you let go of the wheel, except self steering cars of course. The roads aren't flat or even.
