To determine the trailer hubs you need, first you will need to know you trailer's axle capacity. The easiest way to find this out is to look for a plate or sticker somewhere on the axle that provides information like part numbers, lengths, axle capacity. If you can not find a label then other things can be done to help determine hubs needed.

First, find the size of your axle tube: Round with 1-3/4 inch diameter=2,000-lb axles, Round with 2-3/8 inch diameter=3,500-4,400-lb axle, Round with 3 inch diameter=7,000-lb axle.

Second, find the bolt pattern to narrow down hub options.

Third, find size of bearings by either finding the stamped part number on the bearing or by measuring them. You measure them with a digital caliper like Item # PTW80157. Measure the spindle at the inner and outer bearing seats.

Finally, use this information to determine the kind of hubs you need.

When you have an idea what your hubs are, I would be glad to recommend options. I have added a link to our hub selections available for your consideration.
