greese in a greseless waterpump ??

Unfortunately there are several rear bushings/cartridges and it is difficult to tell what you have. Snyder's has three different ones, Leakless greaseless, sealed, packing, packing. Take your choice.

I always stay with the original design, then I know what I have. You pack it, you grease it and you are on your way.

A leakless is going to leak at some point while on the road and you can't repack it.

JMHO...
