Help: 2 axle seal failures on this trip, leaking again

Some seals use an internal wear ring, when installed, they are pressed on the spindle when the hub assembly is installed, and does not rotate on the spindle. Stemco seals usually have a wear ring pressed on the spindle, which makes for a replacable wear surface. If the Stemco was used without the wear ring, it will leak. If a seal was used with an internal wear surface, CR and National use this design, and the wear ring was not removed, it too will fail immediatly.
