Vibration

The "vibration damper" on the front of the crankshaft is properly called a harmonic damper. The vibrations it damps are not the kind you feel in the body or steering wheel of the car; they are the kind which would make the crankshaft subject to breakage like a wine glass shattering along with nearby eardrums when some opera singer hits a high note.

The kind of vibe you feel in the car: torque converter, driveshaft/U-joints, pinion angle, engine and transmission mounts, etc.
