Hoping someone will be able to help. Recently, I've been noticing this weird noise coming from the engine. I can't even really describe it, except it sounds like tire rotating really fast/motor running sound when I am driving on certain roads, or the freeways. It's driving me bananas! While researching on different forums and threads, it suggests that it might be wheel bearing issue. I just had the tires rotated and aligned, with oil change AND transmission flushed over the weekend. Yet, the noise is still there. What else could be wrong? Help!! Thanks!
