How to Pick out Bearing Buddies

Question:

my pontoon boat has bearing caps with a rubber cover that you just push the grease gun tip onto and that way you can grease the bearing in the rear. i need to replace them but cant find them. any ideas where?

Sounds like your trailer has Bearing Buddies like the part # BB1810 that you referenced.

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 # BB1810 that you referenced are for hubs with a 1.81 inch hub bore.
