Hello guys, my name is Brennan and I am new to this forum. I have a 2005 Chevy Silverado Z71 with an L33 5.3L. Recently I have noticed this weird noise after my truck is warmed up and driven for about 20 minutes. It is coming from the front of the truck and it sounds like if you were to but your finger into a fan and stop it. It also sounds like a tire rubbing a wheel well. Im not sure what is causing this but it goes away when I reach speeds of 15mph and up. I know it's not my tires because it happens when im driving straight aswell, and I only have 265s on there anyhow. Any thoughts or help would be greatly appreciated, its left me baffled for over a week now.
