Picking Out Bearing Buddy for Harbor Freight Trailer
Question:
I measured the outside rim of the bearing cup. It was 2.047. I also measured the inside rim on the trailer where the bearing slides in. It was 2.046. Are these the measurements I need to order the bearing buddy for my trailer? I want to order this part as soon as I can.

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. I have included a video demonstrating the Bearing Buddy.
The Bearing Buddies # BB1980A-SS for example are for hubs with a 1.98 inch hub bore.
