Our 4-month-old Raven S exhibited this whine too. At first, I just thought that was normal electric motor noise since it is our first Tesla. However, several 2018 S 75D loaners had noticeably quieter whine so I accepted that the higher pitched and louder whine was a trade-off for greater efficiency with the permanent magnet front motor.
However, I experienced a clicking/chattering/croaking noise during moderate-to-hard acceleration (this is not "shudder") and SC replaced both front half shafts. After I got the car back I noticed the high-pitched whine is completely gone! The slight electric hum is even quieter than the pre-Raven loaners and now I do not hear any whine during regen or it's so silent that I really have to strain with the radio off to detect it. The front motor is definitely quieter after replacing both front axles.
