Time to get a stethoscope from Harbor Freight and do some sleuthing... Might just be the shroud came loose somewhere and is now rubbing. Sound, like water, can travel well beyond where it's actually coming from. Usually, if it's a bearing you'll get an overheating problem with it as friction produces heat....get the stethoscope and hopefully track down the problem. You might look for new worn spots around the unit in the meantime and get lucky....Dennis
