The best thing I have done for you is a bump up.

Check for play in the bearing by trying to move the shaft up and down and back and forth. Also, if you can feel any flex where the shafts meet in the spline that movement will cause vibration. Your best bet would be to take your truck to a drive line shop. They can check for balance and play.
