Default Vibration???

My truck has started i vibration that I think is coming from the rear. It will only do it when i let off the gas to coast down a hill. I am suspecting something like the driveshaft u-joint. What do you guys think? I posted here since it gets a lot of traffic.

No, I'm kinda new to driveshaft tech. How do you check? Thanks for the help.

set the e-brake
put tranny in neutral
crawl underneath your truck
grab the drive shaft
slowly turn the drive shaft (back and forth in both directions), paying very careful attention to the u-joint. There should be no slack in the u-joint between the driveshaft and the flange. If it is really bad, you can hear it cluncking when you change rotational direction on the drive shaft.
