I was initially hesitant to open up my hub motor, but it turned out to be straightforward and nothing to shy away from. Removing the rear wheel is actually more challenging than servicing the motor itself—with one caveat. While others have reported the opposite, my motor came from the factory with comically small cover screws that were heavily coated in Loctite. To make matters worse, these screws had Phillips heads, which are prone to slipping once they hit a certain torque limit.
Using a conventional screwdriver would have almost certainly stripped the screw heads. Instead, I used a hand impact driver ($17), which applies downward and twisting force simultaneously when struck with a hammer. This tool was essential, as I had to pound on several screws to break them free. That says a lot, considering how tiny those screws are.
Other than the fumbly and awkward tire removal and the fun with the screws, this is a pretty easy job. I found that there wasn't all that much grease in the hub and adding some fresh did a lot to quiet the motor.
There is not much grease in there from the factory, but there is more than none.
Easier to see the old grease on the motor side.
Then some fresh grease all around on both, reassemble and your done!
