My 98 GP GT has a bad vibration in the front end. It is mostly noticable when accelerating over 50mph and while braking. I can feel the vibration on the floor board, gas pedal and brake pedal and also on the steering wheel. The steering wheel moves left to right slightly but the car stays straight. (The vibration is strong enough to make my arm shake.) I have had an alignment recently and I have the wheels rotated and balanced every
5k miles. The problem still prosiest. Has anyone had this problem before or know what could be wrong. Any help would be nice! Thanks
