I can't remember any of them I have done having that deflector ring. As a shop owner myself & my techs decided a long time ago that the time required, the frustration and the friggin mess of changing that boot is not worth it when a rebuilt assembly from Oreilly's or Autozone is about $70-75 bucks. Just swap'em out & you're done. I can't remember them having that deflector either, But there is seals on both sides of the hub/bearing assy.
