I had the differentials and transfer case fluids changed at 42k around the time I bought it. The car has been in cincinnati since new, and I bought it in 2010 used--now I'm down south, so it has seen some salt. But man---the bmw engineers need a lesson in corrosion prevention on metals.

I'm only draining and refilling--I'll do the filter at 120k or so.
