Expert Reply:
My online research did not turn up any direct replacement parts for the HB732 hub you referenced. However, we can help you select new replacement hubs.
The things you need to know in order to select replacement hubs are: the bolt pattern on your current hubs (and wheels); the bearing numbers from your inner and outer bearings; the grease seal number; and the axle's weight rating. For example, Dexter Hub # 84546UC3 has a 5 on 4-1/2 bolt pattern, works with inner bearing # L68149 and outer bearing # L44649 and seal # 58846, and is suited to 3500-lb axles.
The linked photo will show you typical locations of these part numbers. If part numbers are not available the next best option is to take precision measurements of your trailer spindles in the locations shown on the photo using a precision digital caliper.
You may care to refer to the linked article on bearings.
