Choosing the Correct Hubs for 3,000 Pound US Cargo Trailer

Question:

Need trailer hubs for my US Cargo trailer. The hubs are 5 and 4 1/2 on a 3,000 lb axle. What hubs do I need to replace the old ones?

In order to find the correct replacement hubs for your trailer, we will also need to know the inner bearing, outer bearing, and grease seal part numbers your existing hubs use. I have attached a diagram showing where these part number will be located on the parts.

If you cannot find the part numbers, you will want to use a digital or dial caliper, like # PTW80157, to measure the spindle. You will want to find the measurement of the spindle at the inner bearing seat, location C in the diagram I attached, the measurement of the outer bearing seat, location D, and the grease seal seat, location B. You will also want to measure the hub bore at the back of the hub to find the outer diameter of the grease seal.

Once you have the part numbers or measurements for your spindle, I will be happy to help you find the correct replacement hubs for your trailer.
