I'm guessing bad water pump bearing is not one of those things I can put off till warmer weather.
Did you go with an OEM replacement? I know that some other popular model waterpumps like Graf/Bosch, etc are of questionable build quality. I've heard alot of horror stories about premature failure from "off-brand" pumps.
