nobody ever thinks of repacking their cars wheel bearings every year. And it's wheels are subjected to the same if not tougher conditions than a trailers.I cannot find a single reason to do this yearly re pack.
Bring a trailer bearing along to an auto parts store. Ask to see a wheel bearing for your truck. Now ask yourself "What could possibly go wrong"
The issue is RE PACKING not bearing strength. Re packing is an issue of loss of grease or degradation of the grease or contamination. There are differences in bearings of course. But simply repacking will NOT make your bearing stronger.
But essentially the two bearing types are the same. They see the same forces (in varying degrees) and types of wear. They are both lubricated either by grease or oil and they perform the same function.
If you feel that the Quality of the bearings is bad then replace them. But the issue is the same, I dont believe there is a need to repack them every 12 months.
