In order to determine the correct replacement bearings and seal for the hubs on your Ranger Boat Trailer, you will need to first remove the hub assemblies. Once removed, you can check for the bearing numbers, which should be stamped onto the bearings themselves. If you are unable to locate or read the numbers, you can also take a few measurements along the trailer spindle where the bearings and seal sit. I have attached an image that clarifies exactly where these measurements will be taken and the particular bearing each location will reference. I recommend using a digital caliper like # PTW80157.

I have attached a link that will take you to our available selection of bearings and seals. You can use the facets on the left side of the page to filter through the different inner diameters once you have made these measurements. I have also attached a couple articles on trailer hub bearings that you might find helpful.
