I am told this part is not available as a repair part and needs to be replaced as a unit with the furnace.

The "Induced Draft Motor" is what you are having problems with.
This small motor is attached to a squirrel cage within a shell and mounted to the furnace heat exchanger. This entire I.D. Motor assembly can be replaced by a licensed contractor.
The vibrations may be the result of an out of balanced squirrel cage, or foreign objects in the venting from hack intallers.
I recently found a seized I.d. motor that failed from having 4 mice crammed between the cage and the furnace.
