In order to pick out the correct bearing buddy you will need know the pilot hole of your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap.

Clean the grease off and measure the opening with a digital or dial caliper. I have included a video demonstrating the Bearing Buddy.

The Bearing Buddies # BB1980A that you referenced are for hubs with a 1.98 inch hub bore.
