Did a bunch of maintenance on my X5 today. She has 197,800 miles on her.
Here's a pic of my transfer case oil with 55k miles on it. It's dark and dirty, which usually doesn't mean much but, all the metallic particles in the oil and at the bottom of the drain pan tells me 55k is far too long of an interval. We drive roughly 90% highway and this is my wife's DD, which is driven pretty easy.
After seeing this today, I'll be changing the transfer-case oil every 40k.
Also changed the following fluids.
Front diff- Had 97k on oil. Still looked/smelled clean.
Rear Diff- Had 97k on oil. Still looked/ smelled clean.
Transmission- Had 55k on fluid. Was dirty but didn't have a harsh smell. Hardly any metallic particular on the pan magnets, which I was pleased to see.
I will do the differentials annually and the transmission and transfer case every 40k from now on.
I used ista to reset the fluid monitors and settings in the transfer case and transmission.
