Mavic Air prop motors low magnetic power

Giving the prop motors, without the props on, a light twist with my fingers shows that three of the motors feel quite weak compared to one of them.
I've started DJI care refresh case which at this point seems to be going well, DJI emailed me a self return shipping label.
I am looking for comments regarding the motors magnetic strength differences.

If it flies properly, it can't be much of a problem.

I think that the 3 motors that "feel quite weak" are probably going to be OK. The Mavic motors are a drum of magnets, that spins around a static core of 9 stator windings. If you finger-spin the drum, you can feel a light vibration as the stators and magnets pass each other (a very light 'judder'). The one motor that doesn't 'feel weak' - could be suffering from a bit of dirt/grass/ hair etc. gunking-up the bearing and stopping it spinning freely. Note however, that if you take the prop's off the motors, and use your fingers to flick-spin the motor drums, the reaction between the magnets and the stators should stop the rotation pretty quickly (i.e. 1/4 to 1/2 turn). That's normal for this type of motor.
The motors are fairly easy to detach from the Mavic Pro - but I'm not sure how difficult they are to get into to clean any dirty bearings ... You can see a simple guide here:

Hi,
My mavic air 2 motor have a sand.
How disassembled it.
My problem is the magnetic cup
