I figured I would start something new for this issue. Has anyone here had an issue with their driveshaft in a 2wd crew cab? Mine is making noise and vibrates the truck at a higher rate of speed, usually worse when it's cold. It has new U-joints, carrier assembly and has been machine balanced. Is this something I need to be concerned about, and if I don't replace it soon, will it cause catastrophic damage to other components? Thanks in advance! I would post a video but it's difficult to hear the noise under the truck because of exhaust and engine noise.
