Anybody who knows about auto repair should probably know this, but I do not. I have a 1998 elantra. Over the course of a few days the car developed a progressively worsevibration in the left front wheel. It is a high frequency vibration, and makes a noise like a fast revving motorcycle. It occurs anywhere higher than 15 MPH; at 70MPH speeds, the image in the rearview mirror is shaking because of the vibration. The steering wheel itself does not vibrate. The vibration gets worse when turning the car to the same side (left) and goes away when turning to the (right). So I like a long road curving to the right. I just bought two new front brakes, but the vibration persists. I'm thinking bearings or the automatic tranny. Anyone have any other ideas?
