Depending on how the trailer was made, there will be a few spots you can check to identify the axle. First, if the trailer was pre-made by a specific company, you may be able to find this information in either the paperwork or on a placard somewhere on the frame.
Sometimes, the axle identity is stamped into the axle itself or into the hub if it was purchased as a complete assembly.
If you cannot find any markings or notation for the axle, you will need to look for replacement parts based on the capacity and dimensions of your existing parts. For example, if your trailer information shows that the maximum capacity of the trailer is 7000lbs, then you probably have two 3500lb axles. The bearings, races, and seals should have an industry standard number on the back edge which can be used to match replacements.
When looking for a wheel to fit your existing hubs, you can find out your existing bolt pattern by taking a simple bolt to bolt measurement. View information on measuring your bolt pattern at the provided link. The # AM20352 wheel you referenced will work for hubs with a 5 on 4-1/2 bolt pattern. With a capacity of 1870lb per wheel, these would be appropriate for a tandem axle trailer with a capacity around 3700lb when matched with similarly rated tires.

I have a home made trailer. The axle came from a mobile home. I would like to change it over to a 15” wheel with hubs. Is this possible. Thanks
