if they are already installed i might use them but really they are throw away money makers for the auto companies and do fail. Check any dealer scrap bin and you will find a quite a few sometimes.If i needed them i would install o.e. tapered rollers though.
But there are millions of cars from all the manufacturers that came with that type of axle bearing. Mopar switched to them in, I think 1970. You very rarely see failures.
