Hello everyone,

I have just purchased a new (to me) 2006 Suburban LS last month. I drive on the highway a lot and I’ve noticed that whenever I drive approximately 50mph+ I hear a very annoying whistling sound, like something catching the wind. This sound happens regardless if it is windy or not. I thought it was the cowl bracket because it was loose but I secured it and it is now tight in place.

the front of the vehicle looks fine, and I should mention that this sound of coming from the front, not the doors. Does anyone have any advice or experience with a similar/identical issue?

much appreciated!
