I had the same problem, the drivers side inner cv joint housing creates a little crater where the bearings ride and causes the vibration only under acceleration or cornering. Mainly only happens on the drivers side. For free, you can swap the cups like in the thread there. I just bought a whole new axle, and the problem was solved.

 

If your are lowered, or have been lowered that is proly your problem. If not it's going to be something else.
You could also try drive shaft spacers.

 

yea i think it is the drive shaft thanks for the help
