Hey Scott! In order to get you the correct grease cap I am going to need you to take a measurement off of your hubs pilot hole or one of your other center caps. The Grease Cap item # RG04-040 you were looking at has an outer diameter of 1.99". This is measured from the outer edges of the cap. If you're measuring one of your hubs you'll need to measure from the inside of the pilot hole across.

Hey Scott, were you able to get the measurement from your hub’s pilot hole or center cap? Once you had that number, did the grease cap end up being the right fit for your trailer? Your update could make it easier for the next person checking their hub size.
