Sounds like a u-joint in the driveshaft.
Do you hear a clunk when you move the shifter from park to drive? ( Loose joint sign)
If so, slide under the truck, ( after you return it to park and kill the motor :shock: ) and twist the driveshaft looking for play in any u-joint. If none, it still may be the problem as it may be seizing up. In that case pull the shaft out and move the u-joint back and forth, it should have no resistance.
