A week ago my truck started shuddering at part throttle above 30mph and it evens out above 50mph. When I get on it half throttle or more it goes away, when I coas it goes away. Truck has 69K miles, hadn't changed the diff fluid having owned it since 8/2011 so I pulled the cover off and cleaned it the gears look new not a scratch on them. Refilled it and drove it, same problem. The U joints have no play, and there is a rhymic squeak coming from back there at 4mph or less so I think something is rubbing while spinning. Anyone have this problem before or ideas what it could be?
Thanks
