DIY vs. "professional" maintenance

Took our 26' tow-behind to a local brake shop

If you must have it done, take it to a reputable trailer shop next time. Not a brake shop. A brake and/or auto shop these days isn't dealing with bearings on most cars like years ago. Bearings are sealed in hub assemblies, and that's what they are used to working on. It's very likely this character has never done real bearings before.

And a good trailer shop knows exactly where to jack up the trailer.
