Expert Reply:

I would be happy to help you find the correct replacement hub, but unfortunately we do not have a breakdown of the specific components your trailer uses so you will need to confirm your bearing combination.

The easiest way to do this is remove the hub on the side that is not damaged and look for the bearing numbers stamped in the face of each bearing as shown in the included picture of the # L44649.

If your bearings are worn to the point that you cannot read the bearing numbers you will need to use digital calipers # PTW80157 to measure the spindle in the locations shown in the included diagram.

Lastly it is important to know your bolt pattern to make sure you get a hub that will work with your wheels. To do this you will want to use the help article I linked that goes over exactly how to measure your bolt pattern.

If you can provide the above information I would be happy to make a recommendation for you.
