Hey Jack. There's no database I can look up that shows me what parts are on a trailer like you can find on cars and trucks. What you'll want to do is pull one of the hubs and look at the two bearings. They should have numbers stamped into the sides of them. I'll need those part numbers to identify your spindle size which will tell me what hub you need.
If they do not have numbers stamped into the side you'll need to measure your spindles using a digital caliper like item # PTW80157. I'll need the C and D dimensions shown in the diagram below.
Additionally, I am also going to need to know your lug nut pattern so you do not have to change wheels. I have linked an FAQ below that'll show you how to measure them if you're unsure.
What did you mean by 10? You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.
