Premature failure of rear axle shaft bearing. Original NHTSA recall # 04v328000 in July of 2004. My car was not in the original recall, but I have just had this very problem with my car. If I hadn't taken the car in, I could have had a major safety problem if the bearing had gone out totally. Please force Ford motor CO. To expand this recall to pay for similar repairs even if not included in original recall. A car with only 50,000 miles should not have this problem!.
