      Comments about National Oil Bath Seal:

      This is the double seal vs the single seal..

      If you have the leaking seal problem with the stock 1 lip seal this may fix it for a long time..

      You will need an A53 inner wheel bearing which is narrower than the regular bearing with the single lip seal..

      These double seals are supposed to last a really long time and if the surface the seal rides on is worn or rusted this might be the only option to get a dry axle/ brake..
