I would not be able to tell you what replacement you need based on the information you gave but there is a way for you to find out what replacement hub will work for you.

In order to find the correct replacement hubs for your trailer, you need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the bearings and grease seal ride. You can use the photo I've attached to see exactly where you need to measure.

Additionally, you need to know your hub's wheel bolt pattern; if you do not know what it is I have added a help article which details how you can find it. If you get back to me with this information I'd be happy to try and help you find the correct hub.
