    Damn it!You kidding right??
    Seems like MOST get away with just the seal,but now you are saying it could be the bearing !
    Have you changed the seal or the the bearing ,on your sms?

    Most of the times it just the seal yet a seal can be damaged due to excessive wear caused by a bad bearing.

    If you take the seal out check the bearing (it might and probably is OK) yet its not a nice thing to change your seal in about a half years time again only to find out that bearing is the culprit.

    Me personally did change the seal on my WR as it was leaking.

    3/4 years later I did do a complete engine overhaul (as the crank went bad) so i changed also all the bearings in the bottom end

    the bearing for the water pump was still OK.

    when the seal is out just check the bearing for play (put the little axel from the pump impeller in the bearing (as it is normally installed and see if you have movement).

    the seal is able to take a 1 to 1.5 mm movement and still perform its function.

    at greater plays it will eventual wear out.

    I understand and makes sense to always inspect the bearing play as well as the impleller or any other parts that one removes.Thanks:thumbsup:
    Just waiting for parts now and then I will update.
