Anyone trying to service the transfer case?
Wondering if that might help reduce failures. I'd like to do a fluid swap on mine, but I was unable to visually locate the drain/fill plugs last time I looked.
BMW is funny with their service intervals. For example, they say the transmission has a 'lifetime fill' but if you call ZF (who makes the auto for BMW) they will tell you that the trans should get a new filter and fluid every 60K for longest life.
The GL5-based transfer case fluid is reasonably priced - just need to figure out how to get the old stuff out and the new stuff in...
