In July of this year I brought my 2010 RAV4 to the dealer to get the suspension TSB done. At that time, the dealer said the TSB fix was no charge but that the vehicle needs an all wheel alignment after the TSB is applied, so I had them do that as well. Here it is 3 months later, I take the car to my local garage to do an oil change & filter and have the tires rotated. He points out to me that my rear wheels have some serious wear/cupping on the inside edges. (All tires were in excellent condition with plenty of tread, near new, at the time of the four wheel alignment.) So I tell him to rotate them anyways, and that I had a four wheel alignment just a few months ago, and I'll see how it goes from there. Now that the worn tires are on the front of the car, the car exhibits what I can only describe as a groaning at low speeds that grows to a howling as the car increases speed. At low speeds you can feel whatever is causing the groaning in the steering wheel. I'm baffled. Did the Toyo dealer mess up my alignment and cause the cupping? Is the tire wear responsible for the groaning/howling? Thoughts? Thanks!
