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 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.

Thank you for the information. Based on that the correct replacement hubs are the Dexter Trailer Idler Hub Assembly for 3,500-lb Axles # 845475UC1. This hub uses inner bearing # L68149, outer bearing # L44649 and grease seal # 58846, which has an inner diameter of 1.719", I do recommend using a digital caliper to ensure that's the same measurement that is on your spindle. The hub also has a 5 on 4-3/4" bolt pattern, which is what I assume you meant as there is no hub with a 5 on 4-1/4" bolt pattern.
