Looks like you have a Bearing Buddy installed. There should be a rubber cover over the center where the grease zerk is located. Something like this may be what you want:

Be sure to order the correct diameter for your installation. If you have any questions contact etrailer.com. They are super helpful and will get you squared away in no time.

Yep. You can order on amazon. Keeps grease from kicking up from the bearing buddy to your hull while trailering.
