Thanks for the feedback. In my lg v30 plus smartphone its so clear the sound and the noise " ta ta ta ta"! In the video give special attention in climbing from 1minute and 50 seconds. See in the motor graphic when i accelerate the noise appear and when the motor regenerate the sound disapear. For me is so clear...Thanks.
Lol, I can hear it and I have 90% hearing loss in one ear, and using crappy earbuds.
Anyway it does seem to match wheel RPM. I guess the gear oil is worth a try; at least you can inspect for any unusual wear metals. Just for shits and giggles, give the tires a good inspection. I have seen "similar mystery noises" arise from stones or other objects embedded in the tire tread. Or even from internal tire damage. For that last hypothesis you could try a tire rotation to see if the noise changes in quality or location.
