Expert Reply:

The two hubs that you referenced come with different sized grease seals. First, hub # AKIHUB-545-2-1K comes with seal 34823 which has an inner diameter of 1.249 inches and outer diameter of 1.983 inches.

The other hub, # AKIHUB-545-2-2K, comes with seal 10-9 which has an inner diameter of 1.5 inches and outer diameter of 1.987 inches.

The outer diameters are essentially the same but the inners are about 1/4 inch off from each other. If you are not sure which size you need you can measure the spindle where the seal rides by using digital calipers such as # PTW80157. I have linked videos for the calipers and both hubs for you.
