Expert Reply:
To determine the correct replacement bearings, races and seals for the oil bath cool hubs on your Ranger Boat Trailer you will want to remove one of the hub assemblies so that you can take note of the part numbers on the existing components. If you refer to the photo I linked you'll see how these parts numbers usually appear.
Experience with Ranger trailers like yours suggests that it may well use inner bearing # L68149, outer bearing # L44649, inner race # L68111 and outer race # L44610. The oil seals we need to measure. You can measure the inner and outer diameters of your seals with a caliper like # PTW80157 to find the correct replacements. You will want the size of the part indicated by the letter b on the attached diagram.
