Question:
I measured the existing caps on my trailer & they measure 2 1/2 accross the top, Im not sure what Bearing Buddies to buy ?

Expert Reply:
The portion you need to measure is not the cap, but the the hub bore. Remove the grease caps and measure the diameter of the opening the caps occupy. This is the hub bore. You will need an accurate measuring devices like a set of dial calipers that is accurate to 3 decimal places.
The Bearing Buddy pair you were looking at, part # BB1781, fits a 1.781 inch hub bore. The measurement you find should match exactly or very close to one of the measurements displayed on the Bearing Buddy page I have linked below.
