In order to find the correct replacement bearings for your Harbor Freight trailer you are going to need to identify what you currently have. I recommend pulling the hubs and inspecting the bearings. They may have the part number stamped in the side, in which case you can use that to find the right replacement.

If they don't have any identifying marks, you will need to take some measurements. I recommend using a digital caliper like the # PTW80157. You will need to measure the inner diameter of the bearings, or the spindle where the bearings ride. Once you have the inner diameter you can find the correct replacement.

I have attached a diagram showing where to measure, along with some help articles for your reference. I also included a link to all of our available bearings which can be filtered down by inner diameter.
