It has two 1.062-inch bearing caps to fit the driveshaft and two larger 1.125-inch caps designed to fit the rear pinion yoke on Ford 8-inch and 9-inch rear ends. You'd replace this when you hear clunking, feel vibration during acceleration, or see excessive rust or play in the joint. It's pre-lubricated and sealed for life, so there are no grease fittings to service.
