Hi Marie; we don't have a way to identify parts for your trailer based on a VIN number. Airstream might have that information if you call them, or you can pull the serial number off of your axle tag. If you can send me a picture of your axle tag I can contact the axle manufacturer to identify which hubs it uses.
If the axle tag is worn or missing you will need to pull off the hub and identify the bearings. The bearings will probably have part numbers stamped in the side. If they are worn or missing you will need to measure the inner diameter using a digital caliper # PTW80157.
For example, if you find that you have a 3,500 lb axle which uses the # L68149 inner and # L44649 outer bearing you can use the Easy Grease Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K. This has a 5 on 4-1/2 bolt pattern and works with 10" brake assemblies like # AKEBRK-35-SA.
