For replacement bearings, races, and seals on your 2008 Airstream 19CB you need the following:

-Bearings: Inner # 25580 Outer # LM67048

-Races: Inner # 25520 Outer # LM67010

-Grease Seal: # RG06-070

For grease you can use the LubriPlate Poly HP-2 Wheel Bearing Grease # L11465. If you need a grease gun as well we have the # L30200 along with the # L70025 to help pack the bearings.
