To continue this thread, I have replaced everything that is obvious, bearings, cv's,tire rotation/balance, brakes, motor mounts.  As previously stated the vibration/harmonic evens out a bit @60mph, but at that speed the increased general noise may cover it.  At slower speeds, a hard right turn makes it go away.  I am wondering if a weak transmission mount (I believe it is original) would cause something like this.  The next thought that I don't want to consider at the moment is the torque converter or the flex plate?  Again any advice about where next to look would be great!  Thanks in advance...
