High Speed Vibration

2002 Dodge Ram Quad 4x4 4.7 with 107605 miles. At highway speeds of 65mph and higher the entire truck vibrates. I have had 4 new shocks, 2 new universal joints, and tires replaced 3 times. At approximately 50000 miles the rear end was replaced by the local Dodge dealer. Since that time I have had this vibration. Prior to that the right front wheel bearing was replaced. My mechanic says that the rear wheel bearings might need to be replaced, since the vibration is more noticable in the seat. I am at a loss on figuring this one out. Do you have any suggestions.
Thanks

Switch the tires front to back and see if the vibration moves to the front of the truck.

If so, it's the wheels, cracked welding can cause harmonic vibrations as high rotations.

If not, it's either the bearings or the rear end.

Since you say this problem started after the rear end change, I'd have them open the cover and check the spider and planetary gears and see if there are shavings in the oil back there.
