I was going home today after school and pulled into the center lane to turn left to get into my subdivision and from when i was nearly stopped to when i was just sitting waiting for the light the car shook quite a bit. It was pretty bad b/c the only shaking ive ever felt was unbalanced wheels, and it was a stronger than that, the whole car shook pretty much not just the wheel or pedals. My bro was in the passanger seat and he felt it was strong too. Then i take off and the shaking stops and park in the garage and the shaking is not there anymore.

Any clues?
