In order to remove and replace that bearing you need to remove the differential assembly. Good chance if one side is worn, the other side is too. I refer you to pages 24 and 25 of the FO-19 NAA service manual. Appears to be a scan of a photocopy, not easy to read. Paragraph 85 describes removal and installation of the differential assembly. Pay attention to the part about the gasket. Gaskets need to be the right thickness so the bearings have the right clearance. Also you may find the gaskets need to be wet in order to fit. Probably a good idea to have a couple extra just in case. No sealant.
The FO-19 manual is available from here.
When putting it together put the right axle housing on first. Then insert the differential assembly and hold it against the bearing race. While holding the differential against the race, jam a couple of wood wedges to hold it in place. Then insert the right axle. The weight of the axle will hold the differential in position and the wedges can be removed. Then the left axle housing can be installed. Then you will want to move on to paragraph 90, wheel axle shaft bearing adjustment.
