Hey Robert, thanks for providing that information! According to Lippert, you need the Timken Bearing Kit 15123/ 25580 Bearings, 15245/25520 Races, 412920 Seal # TMK42VR. Then for the grease caps you can use the Dexter's E-Z Lube Grease Cap and Plug Kit # DX87HR.
Where are you headed with the Reflection once you swap out your bearings?

Couple things I will add: When cleaning the axle, bearings, hub, ... use Diesel Fuel and NOT Gasoline. Gas will linger behind and will ruin the grease contact. After assembly, I will tighten the axle nut, back it off 1/4, spin the wheel assembly, and repeat at least 5 times and the final time of tightening the axle nut, I will back it off 1/8 or less. Not completely loose, but have some allowance for heat expansion. Please feel free to comment if you have a better method. (Knock on wood, dong this I have never had a issue with trailer bearings doing this method.) I am up to learning!
