What is the best trailer bearing to use?
We recommendĀ Japanese bearings for high-speed highway use and longevity.
- Check bearings yearly for water ingress or carbon black deposit in your grease.
- Carbon black indicates bearing wear. The carbon black comes from wear on the casing of the bearings.
- A quick way to check wheel bearings is to jack up the wheel and grab the wheel top and bottom. Give it a good shake from front to back.
