RE: grinding noise and vibration when turning left
I had the very same problem, vibration at low speeds turning left... It started at around 13k, I brought it to the dealer and he thought it was my rotors were slightly warped. I thought to myself, I have no pulsing at the brakes when applied, how could it be the rotors. Well anyways, as soon as I had my leveling kit done everything went away. No vibration at all, problem solved!
