Hello, I have a 2003 chevy 2500 with a duramax and a allison. when I pull my camper or load the bed with firewood I get a viberation. as the veh jounces or hits a dip in the road the sound changes. I have installed rear u-joints and a driveshaft center support bearing and this has not helped. It almost sounds like a bad trans mount but it checks out good. when it empty I cannot feel it. the noise/vib sounds like it may be comming from the front or center of the truck but its hard to pin point. noise/vib is only there between 52 and 65 mph. more pronounced at about 58 mph. thank you, mike mog
