I have a mystery shake in the front end between 63 and 80 MPH. If I get on it hard getting on the freeway, the shake is terrible. If I push through it, it will eventually become manageable but still noticeable. If I ease onto the freeway, it still shakes but not as bad. I've checked everything to make sure it's tight. The front end has been aligned and is exactly where I've been told it should be. The wheels are balanced within a gnats butt. The shocks are less than three years old. I've run out of places to look.. The steering ins tight to the point where it's almost difficult to turn. Any suggestions?
