Trailer bearing maintenance in seasonal inspection

https://wiki-cafe.win/index.php/Trailer_bearing_maintenance_in_seasonal_inspection

When I do my seasonal trailer inspection, I always make a point to check the bearing grease and give them a good spin to feel for any roughness. Replacing the seal and repacking if there's any water intrusion or metal fatigue keeps them from overheating on a long trip. It's a small job that saves a lot of roadside headaches later.
