You gave me a lot of info on your trailer, but what I really need first is the dimensions of the spindle on your trailer so that we can determine what hub/drums you would need. You also will need to know if you have brake mounting flanges on your current spindles as well. I attached a help article that will walk you through the entire process of adding brakes to your trailer as well. I wasn't sure if you planned to add disc or drum brakes so I attached articles for both.

In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out.

Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub or use a dial caliper to get exact measurements of the spindle. The measurements needed are the parts of the spindle where the bearings ride.

If you get back to me with that information I will help you pick out the right hub assemblies. Or, you can follow the link I attached that will take you to the page that has all of our replacement hubs.
