Fan motor noise

2000 F-150 4.6,Lately been hearing noise from fan moter,noise increases as speed turned up .Sounds to me like fan fixen to fall off,air & heat works as it should.Any ideas and if fan needs replacement what kind of job are we talking about?Thanks,Paul

 

Could be something throwing it off balance or
the "squirrel cage" has spun slightly off the
motor shaft.

Remove motor to inspect.

Found instructions for 2002 Blower Motor should be similar
to a 2000 F150.
