Default Alignment question

Can someone interpret the attached alignment? The dealership says the car doesn't need an alignment but it is definitely drifting to the left, even on roads that are crowned to the right.

I'll be honest... I haven't done an alignment since I first purchased the car... I've had zero issues, but I will be doing an alignment when I setup my new 20s on the car.

If no one has answered by then I will upload you photos.

EDIT: Forgot to note, Anything else suspension related worn out lately? How long have you driven on your struts?

I guess what I'm wondering is that even though the alignment is within spec, it looks like the toe is slightly left and could that cause the ar to drift left?

drift left? did you try holding the wheel? lol just kidding. but unless the road is legit runway flat you dont know if it's because of the car or because of the road..

afaik if the paper says its straight then it should drive straight. is the rear adjustable on a 430? on the 300 its not.

same tires? same pressure? could be a dragging caliper, anything... unless it's really pronounced i wouldn't worry about it. these arent self driving cars.. after all..

So what I have heard is that since most roads have a crown for water drain, some will leave the car aligned left a little. But you should be zero on toe to prevent premature tire wear, have them zero it even though it says within spec. Thats why I prefer alignment only type shops, honestly looking at your sheet you are neg camber on the right side and positive on the left, i would see if they can zero toe and adjust right side should correct it.

Even though the numbers could look fine, you may have a bad bushing somewhere. I had a similiar issue with my steering loose over bumps. Turned out to be the front lower control arm rear bushing. Once I easily replaced this part my steering became solid on uneven roads. If you havent replaced this I suggest you try it, as it is a cheap part, and super easy to install. But you will need to realign the vahicle. What happened was that the bushing over time became weak, so when I drove over uneven roads it would flex easier, when on load. Even though it looked normal!

Another thing to try out is swapping the tire from left to right. You might have a tire dragging more than the other side. But before anything checking tire pressure is number 1. But most likely they checked that before the tire alignment.

My GS430 did the same thing for years until I took it to someone that I know that does alignments on performance/race cars. He spent almost 75 minutes rotating tires and making adjustments and driving the car... Eventually he told it was an adjustment on the drivers side rear tire that corrected the pull. Now it drives great and tracks perfect on a flat road... Even on crowned roads it tracks relatively the way it should.

Everyone is correct in rotating tires, but i would also make sure you load the drivers seat with weights also ( most alignment shop will have sand bags they put in to load the car per manufacturer specs ). Rule of thumb is you should be able to go 1/4 mile at 50 mph without making any correction to stay in lane.
Also don't see the individual toe print out
