    You don't do anything. They use a special grease that doesn't run when heated so it stays stuck to the bearings. If you put regular grease in it the special grease will no longer work as designed. Leave it alone and put it back together. When the bearings go bad replace the spindle housing. Welcome to Exmark's non greasable spindle bearings.

    so there should be no grease in the housing itself ......seems kind of strange what keeps moisture out of the housing looks like it starting to rust on the inside of the housing

    That's the way Exmark wants them. The grease they use is similar to Bentonite grease that is used in Pearless gear drive transmissions. Both greases are designed to stay stuck even when heated. Regular bearing grease gets thin and runs when heated.

    Thats why they call them "sealed bearings" they are supposed to remain "sealed"

    The shaft is only thing inside the housing, besides the bearings. It doesn't need to be bathed in grease and rust will not hurt it and should be minimal.
