You'll want to choose a Bearing Buddy based on the inside diameter of the bore of your hub. You can use a digital caliper to determine this. Also, if you know the outer bearing reference number, we can determine which bearing race is compatible with that bearing, and find the outside diameter of the race, which is equal to the diameter of the hub bore.

I've linked you to our selection of Bearing Buddies. The filters on the left side of the page will help you choose the correct Bearing Buddy based on the inside diameter of the hub bore. For instance, if you find the inside diameter of your hub bore is 1.98 inches, you'd use the 3 BBG1980A-SS Bearing Buddy.
