A crankshaft can include a pendulum absorber and a retention arrangement. The pendulum absorber can include a carrier, a pendulum and a pin. The carrier can be coupled to a lobe and can have an opening. The pendulum can have an opening and the pin can be received in the openings to couple the pendulum to the carrier. The retention arrangement can include a retention flange and a retention pin. The retention flange can extend from the carrier or lobe. The retention pin can be coupled to the pendulum. The retention arrangement can maintain the retention pin in spaced relation to the retention surface during movement of the pendulum when the pin maintains the pendulum coupled to the carrier, and can retain the pendulum relative to the carrier through engagement of the retention pin and retention surface in an absence of the pin maintaining the pendulum coupled to the carrier.
