The motor is running by itself - water pump off, gearbox disconnected.
With my stethoscope, it sound like the noise is coming from the upper area of the motor ( opposite the output shaft.
Unless there is some way that mis wiring would cause such a noise, I think I'll have to pull apart the motor and check the bearings.
Its out of warranty.
Wonder if anyone has an exploded view of the motor.
