Water pumps fail from unbalanced fans of unbalance fan hubs. The excessive vibration and loads quickly cause the bearings to fail. Check the fan for balance and if you are running a viscous fan hub check that the bearing in it is ok. The fan blades have to run true and all on the same plane because balance is both dynamic and static.
