There are two ways to measure to determine the correct size of Bearing Buddy Bearing Protectors you will need.

The First way is to measure the outside diameter of the bearing cap installation surface. If the bearing caps are removed gently without deforming them then this is the easiest way to measure. You will need to use a Dial Caliper to take these fairly precise measurements.

The other method of measuring also requires the use of a dial caliper. You will need to measure the inside dimension of the hub that the bearing cap press fits into.

With one or both of these dimensions you should be able to select the proper Bearing Buddy Bearing Protectors, like item # BB2717, to install in the hubs of your trailer. If your hub measurement is 2.717 inches then the # BB2717 bearing protector will work with the hub on your trailer.
