01 4x4 vibration when decel at 60-70mph

Had this truck couple months and not driven it much. Was on the highway Saturday taking sons stuff to his new place for school. When decel'ing between 60-70 mph there was a vibration most likely from the rear chunk or drive shaft I'm guessing. I checked the drive shaft joints not long after getting the truck, but guess one of the u-joints could still be going out. Thought about draining the rear chunk and putting fresh fluid anyway. Any thoughts on what it would be or my best avenue of troubleshooting?

the "rear chunk" is normally referred to as the axle housing, bevel gear set, or pumpkin...... anything " inside" such as gears or bearings normally would make more NOISE that it would vibration....... U-Joints is a good bet, but you normally will feel that under load at 50- 60 mph also.
