Yup, i hear that exact noise when i warm up my rig in the morning. I have no mods with only 600 miles in it. The only difference is that i live in GUAM, about 13 degrees north of the equator, and it never gos below 80 here. So i dont think it could be the weather.EMPIRE said:in the cold mornings, i start up and let clutch out in neutral. i sometimes get a ratcheting sound, not very loud or fast, but i can only describe the sound as being like a chain hoping 3-4 teeth on a sprocket.
