Thanks for any information.
Do not relate passenger vehicles bearings or their care with your Airstream.
You use you vehicle, frequently. Water that collects in the bearings is removed by the heat from the bearings.
Your trailer is used far less frequent. Therefore the water that collects in the bearings, stays there until the next trip, which could be months.
Trailer bearings "AND" brakes must be serviced every 10,000 miles, or once a year, which ever is first. Part of your brakes need replacement every 20,000 miles, or there abouts.
The grease seals should be replaced every 10,000 miles.
These are standards in the RV industry, especially with Airstream, to assure long life for those components, other than brake magnets, which last usually 20,000 miles, or brake shoes, which last about 50,000 miles.
If you chose to ignore that care, you, your pocketbook, and your Airstream, will pay penalties.
