The bearings on both of my sammys have over a 100 k on them,if you do a lot of water crossings I would go with the blue lithieum boat grease in them, for tools I use a pair of ring pliers for the hub clip and a 2" socket for the hub nut's, if the spindle is chewed up it should be cheap to replace just call trail tough or one of the other venders just ask for a good used one! welcome aboard.
