    Is it at any speed inparticular, or all speeds? To me, it sounds like it might be u-joints going bad. It could also be tires that are not properly balanced (more likely if it is only occurring at certain speeds)

    If everything checks out OK (check the pinion bearing and extension housing bushing for play too) then I would change the u-joints first.The may look\feel OK,but they can get dried up on the inside and cause a heck of a vibration.When you get the shaft out,you will probably find them pretty stiff to move.You will need to burn out the fiberglass retainers to replace them (if OEM).
