Do you feel the vibration in the steering wheel? If so check the front end for balance. I wonder when you put it in reverse it clunks, This is what I would do if it was my truck. Jack the back up so the wheels are off the ground and it in neutral, turn each wheel to see if there is play anywhere. Check the fluid in the diferental. If all seems good check the universals. If they start to go bad they will make a clunking sound. I had it happen to me and I did not think it was anything until my driveshaft fell off.
