I have a '13 JX35 that I purchased back in March with 34K on it. About a month and a half ago I noticed a loud vibration coming from the front passenger side. The sound increased as I sped up and decreased as I slowed down. However, nothing can be heard up to 30mph. I immediately thought it was the wheel bearing assy. I have a private mechanic that I take my car to all the time. Usually I buy my own parts and this time I got them from Auto zone. I had 2 selections for my truck (AWD) so of course I went with the cheaper option by duralast. I took it to my mechanic and he says it was the wrong part (too small). So i go back to autozone and compare the more expensive version of the same part (Moog) and noticed that was much bigger. My mechanic installed it and the vibration noise went away. Now I am noticing some shimmying in my brake pedal and steering wheel every time I brake from highway speeds.
My thinking was i need to turn the rotors (heat spots) but I would feel the shimmy at low speeds as well.
In my past experience, a bad wheel bearing can cause havoc on the suspension system. I think I may have a worn tie rod.
Anyone else experience this problem with the wheel bearings so soon?
