Who sells a new driveshaft for a 2004.5 srw quad cab short box? I have a stock one pice driveshaft, but have had nothing but problems with it. I have a vibration from 60 mph to 70 mph. The driveshaft has had the u joint replaced twice, the driveshaft has been balanced twice, and now I installed a blance masters balancer on it. All this has helped a ton, but I still have a vibration at these speeds. I have had the truck to two different dealers, and neither one can get this resolved. They also won't get me a new driveshaft, so I will just buy my on if I can find one.
