I figured that I would post an update to this topic since its on going. I have searched all over the forum for 4th gen bearing issues and seem to find a lot of unidentified vibrations which turn out to be the related to the wheels, tie rods, or drive shaft. After dropping a good chunk of change on changing the plugs and fluids at the dealer today ($600). I had them take a look at the wheel bearing again. And again, they stated that is the wheels just making road noise.
I am indeed skeptical. There is a low speed grinding noise, worse when turning right, even a dead spot in the stearing at speed. I pretty sure that its the bearings. The dealer is claiming that since there is no play in the hub assembly that its fine and they won't change it. The vibration is normal and regardless of having the tires rotated, aligned, etc. the vibration is coming from the tires. I just don't buy it. I mean if the vibration moved from one side to another from the rotation. Ok, that would makes sense to me. This does not. I really have no recourse other than being pissed that I will have to pay out of pocket to replace my bearings.......pissed.......
Someone tell me I'm wrong and that I am a complete moron for not realizing how my tires are supposed to sound with normal vibration and grinding at low speed
Oh and yes if they were "bad" they would be covered under warranty.
