Replacing motor and fan wheel in the 8525 will take care of the squeal but the roar is due to burner and air flow design that created an obstruction...hence the noise.
Same with the 8520
NEW 8500 Series have been redesigned with a new burner and blower assembly. The new design has eliminated the obstruction and minimized the turbulence in the blower housing resulting in lowering overall noise and an increase in the airflow.

Motor alone would be $100
Blower wheel roughly $25
