Furnace squealing

[Dank1945]

My 1999 fleetwood flair furnace squeals very loudly for the first 5 mins or so after turning it on, then gradually less and less. Obviously it must be something in the motor. Probably bushings or brushes? Has someone dealt with this before? New motor is arou d 120, so if it is a matter of changing $2 brushes or bushings I would rather do that.
Thanks

Had the same issue in our Bounder. Replaced the fan motor and not only is it so much quieter but moves more air. We finally got tired of the noise and was afraid the bearings would seize just when we needed the heater the most. Chuck

I have the 82 pace arrow and somehow a bunch of the mud dauber wasps have gotten into the outside exhaust system and built there mud nest in there and I need to remove the furnace to replace fan motor
I have gotten everything disconnected to pull it out but I'm hung up on the exhaust pipes being connected from outside how do I get this part disconnected to be able to pull it the rest of the way out so I can get at the fan motor
