I would be happy to help you determine the correct replacement hub and drum assemblies and braking assemblies for your 1993 Bison 2-Horse trailer, but unfortunately we do not have a break down of which components were used on a specific trailer.

Starting with the hub and drum assemblies you will need to know which inner and outer bearings your current hubs use, and the bolt pattern of your current hubs.

The easiest way to find which bearings your hubs use is to remove one of the current hubs and look for the bearing numbers stamped in the face of each bearing as shown in the included picture of the # L44649.

If your hubs are worn to the point that you cannot read the bearing numbers you will need to use digital calipers like # PTW80157 to precisely measure your spindles according to the included diagram.

I have included a link to a helpful article that goes over how to measure your bolt pattern to assist you.

Moving on to the braking assemblies you will need to know the axle rating of your current axles. You can do this by checking the axle tag on the center of the axle facing rearward, or if the tag is unreadable if you can send me the GVWR of the trailer plus the number of axles I can use that to determine the axle rating.

If you can send me over this info I would be happy to recommend the correct components for you.
