I would have the tech use the chassis ear and check for a wheel bearing.
Could you elaborate? Is it a test with instrument like a doctor does?
I am in the same boat. I repaired one badly hit wheel (pic above), now a second one, inspected closely the 2 others (no hit).... and I have a loud road noise. My RFT tires were very quiet when new, I can't believe that they could become so noisy.
I had the car lowered with Eibach coils (similar to sport pack level - mine had not this package) and only the realignment was done at the dealer. In your opinion, would it be ground to deny the repair on warranty of the bearing, if it is the case?
