In order to find the correct replacement hubs for your trailer, you need to first know 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. Finally, you also need to know the weight rating of your axle to determine the correct hub.

To determine the brake assemblies that will fit your trailer, you need to know your axle's weight capacity, the size of your wheels, your mounting flange bolt pattern and the inside diameter and depth of your hub. I've added a link to our page with our selection of brakes for you to take a look at as well as a help article on adding electric brakes. If you get back to me with this information I would be able to tell you what you'll need.
