Expert Reply:

Without having the exact serial number for your axle these are the bearings and seal your Dexter 3,000lb axle will most likely use. You will want to verify this with either taking apart one of the hubs or sending me your serial number on the axle tube.

Inner Race # TMK95FR
Outer Bearing # TMK29FR
Outer Race # TMK55FR

Hey, were you able to confirm the bearing and seal sizes for your Dexter axle on the Airstream? Knowing what you found could help others trying to match parts for similar setups.
