I'll have to disagree. The fan is VERY easy to take apart and lubricate. Remove the old fan and just pry out the plug adapter. Take out the ONE screw on the end of the fan housing and just pull the motor out. You don't even have to take the cage off. POC ...! You may find the brushes are worn and the connector wires are getting tight. If you're handy with a soldering gun you can heat up and uncrimp the connection and slip the wire a bit to get more slack. Just a little more work than doing a replacement and you should do the same procedure anyway with any used fan you're thinking about using.
