Thanks. I do hear a loud rattle sometimes like something is loose. I'll check that out. It's a service body bed and between the laptop mount, ladder rack and all the boxes stuffed with tools there is always something constantly rattling. The tires are the biggest thing annoying me right now. They started off quiet and now it sounds like I have big ol monster tires on it they are so loud.

Never mind, I think I found the problem. I have a laptop mounted in the truck, and the cord that plugs into the socket was ajar and when its loose it causes a clicking sound.

I have a 2015, 2500 Silverado with 151k miles on it. Twice in the last two days I've heard a random clicking noise, sounds like a relay coming from near the steering column in the dash. First time it happened after a few minutes of driving, and today it happened after about 10 minutes. It's like 3 or 4 random clicks. Any ideas where to start looking? As far as I can tell nothing is not working.
