Agreed, glad you stopped and found it and are save.
Here in MN, the land of lakes and trailers, this is a fairly common site on the roads.
Because of this I hate Bearing Buddies, they promote over greasing and a false sense of security.
Trailer bearings should be taken apart and checked at least twice a year,
in spring and roughly half way through summer.
Having a replacement set of bearings and even a hub in the out of town tool kit is also common here.
Dan
another good tip is to never put your hubs in the water, let the rollers on the trailer do their job.
