If bearings on a vehicle are serviced properly on schedule, they tend to be the most overserviced item on the vehicle. Bearings rarely go bad. If yours are bad, I wager they weren't serviced properly to begin with or you have towed your trailer repeatedly through a slit-ridden stream.

I would have a personal look at them. I just towed my 326 home a few weeks ago and plan to have a look at the bearings and repack them with my grease of choice along with installing a wetbolt kit and removing the china bomb tires. Being proactive in the maintenance end of "towing fun" pays dividends...especially when accomplished by yourself. Trust, but verify, as someone greater than me once said.
