"Lifetime". What an awesome word.. for ze BMW bros.

Can't decide when to change the differential and transfer case (just another diff) fluid. BMW calls for 100k miles. I'm at '62k. Here I am having auto tranny problems.. so I'm also thinking about preventative maintenance on the diffs. But then again.. diffs are waaaay simpler than transmissions.

Anybody changing oil sooner than 100k? X is going in next week for auto fluid refill anyway. I don't want to spend the extra coin on the diffs unless you guys feel it is important at 62k.

Thanks a bunch.
