Expert Reply:

There are 3 possible hubs for your trailer. To determine the correct hub you will need to remove one of the hubs it check for the correct bearing/spindle size. If you can read the numbers on the bearing you are looking for L44643 or L44649. If unable to read bearing numbers you can measure the spindle with a Digital Caliper # PTW80157.

1" Spindle(L44643)
- # AKIHUB-440-2-G-1K for non EZ Lube Axle
- # AKIHUB-440-2-G-EZ-1K for EZ Lube Axle

1.063" Spindle (L44649)
- # AKIHUB-440-2-G-2K for non EZ Lube Axle
- # AKIHUB-440-2-G-EZ-2K for EZ Lube Axle


If you don't have an EZ Lube Axle I recommend adding the Bearing Buddy # BB1980A-SS in place of the traditional grease cap. This will allow you to easily grease your bearings when maintenance is required.

If you have a different bearing or spindle let me know and I will help you determine the correct part for your application.
