#0451740 on the bearings. If you have the cases split a little heat from a propane torch around the bearing then slap the case on a block of wood. Bearing should fall out. If you can't do it that way rent an inner bearing puller from any good auto store for a refundable deposit. Have the new ones in the freezer for awhile. Heat the case area and the bearing should almost drop in. May take a couple taps to flush.See if this video helps.
