Atwood/Dometic furnace motor updates?

Got a Atwood 8012-II furnace that is starting to chirp so I'm guessing that I'm going to have to replace the motor in the near future here. Looking up the part shows the original motor is part number 36122 which has been replaced by part number 30135. I've seen suggestions that some motors may have been updated with actual bearings instead of just the brass sleeves but no actual hard proof of this. Wondering if anyone out there knows anything about the updated furnace motor part numbers.

I ordered the new 30135 motor from a dealer and the part that showed up says 36122 on it. Would hate to replace the motor with the original unit especially if it's been updated to resolve issues. My motor is only 7 years old which seems like a really short life for a furnace motor.

The dealer assures me that they are all the same parts but you know how that goes...

Iโ€™ve had good luck lubricating those motors- as long as the shaft isnโ€™t worn, I drill a hole in each end bell and apply oil to soak the felt.
First did it after I installed a brand new defective motor (it squealed), and the customer was leaving.
Was still working years later.

Thanks for the replies. I guess I'll forge ahead and use the legacy part number item. Fingers crossed I get more than 7 years out of the next one, oof.

You do not want roller bearings in a living environment. They are noisy beyond belief. Think about it, all the electric motors in your home and RV have bushings for a reason.
As an example, all high speed printing presses have bushings on all the shafts. The noise/vibrations from roller bearings would show up in the print.
