Maybe this mechanic is incompetent. For the bearing to crack three times in ten days indicates to me that something more than the wrong grease is at fault. The previous owner had this bearing go on him twice in a very short time and that was a big reason why he sold the car. So this is not a new problem on this car. However, that said, I am an ignoramus in the world of SVXdom (if not the world of cars in general) and I am open to all diagnoses of my problem. Nick
