I would be happy to help you find the correct grease seals for the two 4000lb AL-KO axles on your Forest River Flagstaff, but unfortunately we do not have a break down of components used by a specific trailer.

Instead you will need to remove one of your hubs and use digital calipers like # PTW80157 to precisely measure your spindle where the grease seal rides as shown in the included diagram, and measure the inside of the hub where the grease seal rides.

if you can provide these measurements I would be happy to recommend the correct replacement grease seal for you.
