Measure the inside diameter of the hub or the outside diameter of the dust cap shoulder (the part that fits into the hub) with a caliper or micrometer. The measurement needs to be in thousandths of inches. Most marine dealers, auto parts stores and service stations have a caliper or micrometer and will gladly measure your dust cap for you.

e bearing buddies alright to install on an RV travel trailer, 7,500 lbs. with electric brakes?
The Bearing Buddy wheel bearing protectors eliminate the need to repack bearings with grease and do work just fine on an RV trailer. Weight and type of brakes would not make any difference in the Bearing Buddies ability to protect the bearings from needing to be repacked with grease.
