Hyundai Entourage High Pitched Vibration/Whistle noise
When I travel over 70 mph I hear an intermttant, high pitched, vibration/whisteling noise. It is very sporadic and gets softer and louder. For that reason I think it might be air rushing through/over something in the van. I think it is in the front part as well. It also really doesn't happen unless I am going about 70 or over and how much it happens then just depends on the day.
I had my tires balanced and it still happens. The technitions also looked under the car for any loose material that could be causing the noise and everything looked fine. They also took it out twice but couldn't reproduce the sound. I will go out with them some other time when I have some time to actually do that.
I was wondering if anyone else has this experience?
