Vibration
 This 4Runner has been in the dealership 4 times for steering vibration / flutter / pulsing.  The area Toyota technical rep has been working with the dealership to determine and fix the problem. They keep changing and re-road force balancing the tires and nothing works. They tell me that this vibration is normal for the vehicle and they are just tring to get the best set of tires that give the least vibration. It seems that it is not possible for it to be fixed. Toyota quality is not what I thought. An unhappy owner with 2000 miles.
