Trailer makers like Jayco do not maintain detailed online specs on the small components (like grease caps) used in fabrication of their trailers but it is easy enough to take one measurement of your hub's bore to determine the size Bearing Buddy you need.

You'll want to use a digital or dial caliper like # PTW80157 to measure the hub's inner bore. Please see the linked photo. You need to measure carefully and take the dimension to three decimal places, such as 1.234-inches as an example. You also need to note whether or not the hub bore is threaded; some hubs have this feature while others do not. We have Bearing Buddy protectors for both types of hub.

The linked page displays all bearing protectors. Click on the filters for threaded or non-threaded types then select the dimension nearest to your hub bore measurement.
