How to Determine Hub and Drums and Brakes for Trailer

We can tell you how to determine the correct hub and drum and electric brakes for your trailer, but do not have any way of knowing what is on it right now.

In order to find the correct replacement hub and drum 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 digital caliper 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, as well as a printable bolt hole template you can use. If you get back to me with this information, I'd be happy to try and help you find the correct hub. I have also added a link to our entire selection of hub and drums for you to come back to.

As for brakes, what you need to know is also your axle capacity, as well as the brake mounting flange you have, and the depth and diameter of your drum. For example, if you had the Dexter Trailer Hub and Drum Assembly for 5,200-lb to 7,000-lb Axles # 8-219-4UC3 you would use the Electric Trailer Brake Kit # AKEBRK-6.
