High pitched sound from furnace

My Armstrong High efficiency furnace is making a high pitched sound. It kind of sounds like locusts. When I run the fan only, there is no sound. I can hear the sound coming from the inducer assembly. My questions is:

Is there anything in the inducer assembly that can be adjusted/lubricated or should I just replace it?

I see that the motor is detachable from the rest of the assembly. Does the whole assembly (black circular piece with a couple hoses and pipes attached) need to be replaced, or can just the motor portion (motor portion is by FASCO) be replaced?

Typically the inducer motors have sealed bearings. If the motor is squealing it is time for a new one. You can probably find a motor but getting the wheel off is almost impossible without damaging the wheel.
Inducers are usually sold as an entire assembly which makes it easier to replace.:santa:
