How Often to Repack Trailer Wheel Bearings?

By the book once a year.

IMO the first repack should be done within two years. Once you are certain the pack was done properly I would go at least 5 years or 30,000 miles. Just did mine at 10 years when installing disk brakes... all was fine.

I'll have to agree with this strategy. IMO every year is just silly, and either mostly wasted labor and/or money.
