Vibration when I get off gass pedal
I've searched for this specific issue. I am feeling a vibration whe I get off the gas at above 40 mph. Once back on the gas it seems to go away? I can also make it go away if I load up the left side by seering hard right. once the trucks load is even or on itsl right side (again off the gas) I feel the vibration again? I was thinking driveshaft/u-joints???
Any suggestions?

Universal joints or possibly a hub/bearing assembly. U joint vibration is most noticeable at 35mph and 70mph. Above or below those speeds it's still there but not as bad. Loading one direction or the other doesn't usually make a difference with U joints, (on and off the gas does) that's why I mentioned the hub.

As these rears are usually solid-it is all dependant upon the mileage and use of the unit!
maintenance plays a factor as well.The diff cover rusts on these axles promoting fluid loss also-which leads to bearing loss! Just check the whole drive line to be sure,but seems like u-joints to me...

Awsome feedback guys! The vibration has also a humm to it as well. The truck has 107K on it and is in pretty nice shape, however I do know for a fact that it was not moved for over a year until I bought it...

When they sit like that, it's quite possible for a U joint that is low on grease to partially seize and bind. You might need to remove the drive shaft and make sure the joints pivot smoothly in both directions.
