I'm hearing a knocking sound from the front end of my '99 X/C when making sharp turns at a moderate speed, such as turning into a driveway. Sometimes it's a single knock coming from the left front. Other times it's two knocks coming from the left and then the right in succesion. I've been to two different dealers a total of 4 times and both claim not to be able to hear anything. The front swaybar links have been replaced, the steering stops greased, the sub-frame bolts tightened, lower ball joints and tie rods inspected. None of these things have solved the problem. I called consumer affairs a week ago, and have not heard anything. Has anyone else had this problem and know of a fix?
