Hey guys - the noise is totally gone so I can not check to see if its the CV's. I did get it on jackstands and got the car to "100mph" and played with several RPM ranges and nothing back there looks off.
However - the driveshaft's center bearing (the rubber all around it) is cracked in several places and you can "shake" the driveshaft by hand. Is this whats causing the vibrations? What do you guys think? Medium pressure with my thumb can move the driveshaft up and down.
