I got new tires and had them force balanced. My previous problem with vibrations is now not from the tires/wheels. What else it could be? Ball joints? Axle? Tranny? My tranny or something makes an odd noise while at idle, when pushing the clutch in seems to be less obvious. Some one told me it might be the throw up bearing? Could that cause all this? The vibration is like when your rotors are warped and you push gently on them, or when your tires are not balanced and coupled.
