Hi guys.

This has happened 3 times now in the last 3 months. While driving on the highway anywhere from 55-70 my car sometimes randomly starts to shake violently, to the point where I need to move over and slow down to let things calm down before accelerating back to speed. The shaking lasts maybe 2 minutes at most using this method.

Ideas are: unbalanced tires, calipers sticking after tapping brakes, hub assembly? (My anti-lock and brake light has been on for 4 years now), rotors.

Is there anyway I can pinpoint the issue or at least get a better idea the next time this happens. I have read some crap about throwing the car in neutral when it starts to determine if it is related to the brakes, but I will not be putting myself in neutral on the highway.

Thoughts, ideas...all welcome
