have a 2000 subaru legacy outback that I bought with 5,000 miles on it. It has had a frontend shaking between 60 and 70 miles an hour - always. I have 96,000 miles on the car now and have gone thru 3 sets of tires. Have have the tires rotated and balanced as well as aligned at least 4 times a year. It seems that when the tires are cold, the shaking is worse. I have put it into neutral on the highway at vibration speed and the shaking continues. The dealership has always maintained that there is nothing wrong with the front end. I still have 4,000 miles on my warranty...any suggestions before the clock times out : ) cheryl
