Yo G,

I wonder if they changed all that suspension stuff for nothing. Mine had the same sound under the same highway conditions, and I deemed the problem to be the high speed air flow causing the licence plate to rattle. I slipped in a small piece of rubber and the noise went away. The noise was so loud, I thought that the engine was about to blow from the front of the car. The engine did eventually blow, but that remains an unresolved story for another forum topic.
