Veering to the Right - 2015 Hyundai Sonata Long-Term Road Test


Our 2015 Hyundai Sonata sedan has a tendency to veer to the right on the highway. We took it to a tire shop to have it checked out.

Apparently the Boyz that put this new Sonata together missed the rear end.
A print-out would be nice right now, but really not necessary. Rotate the tires back to their original positions and see what happens.
the business that doesn't feel the need to nickle and dime their customer is the business that gets my loyalty.
i'm a born and bred capitalist... but greed is not good. i get the sense you are one of those "my way or the highway" kind of guys...

"When the rear tires toe in or out unevenly, tracking will be changed. For instance if the left rear wheel toes out 1/8 inch and the right toes in the same amount. Total rear toe will be zero, but the vehicle will track off to the left. With a straight frame and unibody, rear alignment is always the cause of improper tracking."

The original article linked to Tire Rack and they had thrust angle explained correctly as well.

I mentioned thrust angle. A rear toe issue that isn't equally divided between the rear wheels will cause the vehicle to "dog-track" which from the drivers perspective results in the steering wheel being off center, but it again does not cause a pull or lead. Claims that toe angle issues cause a pull or lead from either the front or rear axle are a myth. The fact that you can find a quote from someone who should know better but got it wrong only means that the subject is more complicated and demands more training then most take it to be.
BTW rear toe that is simply out of spec but equal side to side causes the tires to scrub when going straight ahead and get's really complex when turning especially if the vehicle is designed with passive rear wheel steering.
From Tire Racks linked article An incorrect thrust angle is often caused by an out-of-position axle or incorrect toe settings. So in addition to the handling quirks that are the result of incorrect toe settings, thrust angles can also cause the vehicle to handle differently when turning one direction vs. the other.

For all of that effort they didn't draw the centerline of the car and show how the total rear toe causes a thrust angle which would tend to move the rear of the car to the left. The result is that straight ahead from inside the car also has the front wheels be turned towards the left as well. That would result once again in the wheel being off center and not a pull or lead. An alignment correction could be done in the rear which could bring the thrust angle back to the centerline of the car and then the front toe reset to specs with the wheel in the straight ahead position, or the front toe only could be reset leaving the thrust angle present (especially if the rear isn't adjustable) and that would end up with the steering wheel straight.
