 ```Jack, I have been driving my friends BN4, on and off, while he is deployed on active duty. It had a bad shake around 55 - 60 mph, even after the wheels had been balanced off the car. I then took the car to an alignment shop that has been around forever, where they actually knew what a Healey is, and had the wheels balanced on the car. Not only is 98% of the shake gone, but he also fixed the pulling problem. I have always been told that the only way is to balance them on the car. Thanks.
