Can you verify both U joints are in line on the driveshaft? The driveshaft looks to me to be too short...If it's not into the tail shaft bushing far enough it does wobble and will cause a vibration. The splines and the tail shaft do not control the yoke as much as the bushing in the tail shaft housing does.  Yes, both u joints are in line with each other.
