I have a 2004 Civic EX, 38,000 miles, which I purchased in July 07. In November 2007 I took a road trip and discovered at higway speeds (higher than 70 mph) there was a loud squeal that sounded like it was coming from the passenger side of the car.

It seems to be aggrevated by high winds. In blustery weather the squeal can be noticed at 60 mph. I've never heard it at any speed lower than 60 mph in any weather conditions.

The windshield was replaced in August. Three tires have been replaced since I purchased the car, the other was brand new when I bought it. Actually two were new, but on this road trip I got a flat and bought a tire on the road.

Any ideas what the squeal could be from before I take it into the dealer?

 

could just be the sound of the wind whistling through the dynamics of your car? sounds stupid but i hear weird sounds when wind whips at my car at high speeds.
