Helpful Expert Reply:

Based on your inner diameter of 1-1/16 (1.063 inches) the replacement trailer hub bearings you need are # L44649. The matching race is # L44610. I highly recommend measuring the bearings and seals with a digital caliper tool to the thousandth of an inch. You would need to remove your hub to obtain. See the diagram to the right.

I have included a FAQ and video review for you too.
