I don't know your mechanical abilities, but in my opinion it's a super easy motor to work on. The really great part is that all four brushes are right behind that plate. VERY easy to put back in, compared to most other motors, where you need to have about 16 really tiny little fingers.
As far as you are from service, I (myself) would definitely open it all the way up by removing the motor. There is a couple of braided copper wires that connect the brush set to the stator windings. They are soldered in. Still, it would be pretty hard to break them. I doubt you could damage anything to the point of not having your warranty not honored.
After removing those two bolts the entire motor comes out quite easily. Then you can pull the end cap all the way off and examine it. Do that over a work surface that allows easy retrieval of any of the brush springs that may fall out. Like, don't take apart over a field of grass or weeds.
Obviously, disconnect the power before trying any of this.
