All of a sudden the radiator fan on my 700 has started to make a loud squealing noise whenever it's running. I hosed the radiator out and all the areas around the fan but that didn't seem to help. The fan seems to be working properly but the noise will drive you crazy. Has anyone else had this problem and if so, what is the fix?

 

Happened on my HO. It is the bearing and it will eventually lock up completely. I replaced mine before it quit, but I know others who did not.
