When you replace the bearings with Timkens, you also MUST replace the races in the hubs with the Timken races. I did this several years ago after having one of the Chinese bearings fail while on the road. All the numbers quoted are universal trade numbers for these bearings and Timken bearings are made in many parts of the world. Timken bearings may or may not be 100% made in the USA, but their quality control and reputation for all their products makes for a dependable bearing.
