Someone might have used anti seize and over tightened them. Local alignment shop did that with my wheels. I had to take them to the dealership so they could use their big ugga dugga on them. That did the trick.

Oof, I did the same thing to my car. Ended up replacing the radiator. Such a dumb cost savings thing manufactures are doing. I should have just went with an all metal aftermarket solution instead of the OEM, but I needed my car back asap.
