Differential and transfer case fluid changes?
I tried asking our dealer and they insisted it was "good for life" but we all know that means life of the warranty.
I can't find any useful guides or videos on how to change the fluid for the differentials and transfer case. I did the transmission. And I do mean differentials, for some reason AMSOIL lists 4 differentials! |

I should add, I'm at 65k miles and the transfer case has already failed and been covered under an extended warranty, so I'm surprised this maintenance is not more common. Ya'll need to get out there and change your fluids!

I answered my own question on the transfer case. This TSB gives the details on how to do it: https://www.tsbsearch.com/BMW/SI-B27-02-20
Now I'm just curious about these multiple differentials... |

Detailed may be a little hasty.
I’m having issues getting any kind of a tube into the hole and into the fluid. Seems like BMW just wants to make it damn near impossible to service your own car. 2019 40 |

Been reading a lot lately about the transfer case issues that seem to plague the x5 and more particularly the v8 versions. I personally have a 2022 x5 m50i so the TSB listed above does not list my vehicle but I ASSUME that 2021+ models would have the same issue too right? Or did BMW do a update for newer models to avoid this issue?
With that said, does anyone know if its recommended to change this fluid every 10K or 20K miles to prevent wear and tear? I haven't found anything indicating regular changes but also don't want to have my transfer case go out anytime soon as I LOVE my m50i. |

Lubed for life! Well, not so much. How hard would it have been to add a drain plug? What were they thinking?!
