Both front wheel bearings went out at 14,000 miles. Dealer replaced, but only turned rotors and would not replace worn tires.
At 24,000 miles I had to have the rotors turned again. Dealer refused to replace them. Said they did me a favor by not charging me for turning the rotors.
I'm guessing not saying that you probably make sharp turns pump your brakes, or maybe brake to fast?? I had the same problem with a Taurus gl, but I understand why now... it because I was used to driving a smaller car and sedans don't corner as well.
