I'm getting a harmonic vibration coming from the drivetrain. Center driveshaft bushing doesn't show any signs of tears or "looseness" when I pry on it - however, I did notice that the gap that runs around the circumference of the bushing is wider at the top - is this the normal state when at rest (maybe because of the weight of the driveshaft)?
