I have fiddled with these and find that rebuilding is a little difficult but can be done. One motor I saw had a plastic squirrel cage that was molded onto the shaft. I have no hope of rebuilding.
but the others have a detachable squirrel cage and so you can take the brush plate off. the front bushings of these motors are goofy swivel-type things. Like a magnesium marble with a hole drilled through, mounted so it can swivel. My favorite electrical motor repair place says replacement swivel bushings are not available. Oh by the way, the screaming you hear is this bushing.
Anyway you can ream this thing out carefully with a rotary tool and press in a standard brass bushing. If you do this, use a LONG bushing. The swivel thing is deep.
Of course, you could also spooge some moly grease on that screamer and it might get quieter for a while. I think you can also turn the motor upside down. Might help for a while. These things die eventually because of that goofy front swivel bushing.
Brushes are easy to find. And yes, mine is just unplugged and I don't miss it. My drivers' side heat burns my leg sometimes.
