I just starting noticing that when I'm at slow speeds and go over bumps I hear loud shreaking/creaking sound coming from possibly my shocks. I know it's definitely coming from each tire under the truck. It's so loud, I kid you not it sounds like I'm driving a 40 year old truck. It's embarrassing. I drove with my window down today to see if you could hear it outside the vehicle and you definitely can. How can a truck with less than 15k miles on it sounds like a clunker. Is anyone else experiencing this kind of noise or know what it could be?
