The best way to determine the replacement bearing, race and seal parts needed for a trailer is to pull one of the hubs and remove them so their part numbers can be noted. Usually bearings and seals will have part numbers stamped or molded into them, as you can see in the linked image.

You can search our site using those part numbers to see if we offer them. You can also measure the spindles on the trailer's axle at the points B, C and D noted in the image using a precision caliper like # PTW80157. This will allow you to use those dimensions to search for matching parts. I also linked our main page for bearings, races and seals.

I checked the documentation for the Haul-Master trailer 92174 but it does not specify the bearings used. This is not unusual with bargain imported trailer kits which often use unusual parts not commonly available. It is sometimes necessary to obtain replacement parts from the trailer maker.

You can refer to the two linked articles on bearings for additional information.
