I was unable to find any reference to a Dico 45264 hub. You will need to take some of the measurements to make sure you get the correct bearings and seals for your trailer.

Trailer manufacturers use many different sizes when they build their systems and without precise measurements, we could not be 100 percent sure. Digital calipers are available at most tool supply stores. I have attached a drawing that shows where you can take the measurements.

We would need to know the inner diameters of the inner and outer bearing and the grease seal. These measurements will need to be as precise as possible. I have attached a link to a helpful article that explains how to remove, and reinstall bearings you can check out.

Would you have a hub for a 86 trailmaster boat trailer? Thanks.

We might! But unfortunately there's no way for me to know what type of hub is used on your Trailmaster Boat Trailer. You will need to pull one of the existing hubs and check for the bearing numbers that are used - they should be stamped inside the bearings themselves. If you can tell me this I will be happy to recommend a good replacement.
