At 137k miles I have changed the transfer case fluid, both differentials fluid, and the cabin filter. And the spark plugs with some new Bosch plugs with the Anti Seize.

The other plugs were done at 100k miles but my mechanic had a hard time getting the number 5 plug out. He had to spray penetrant in there over a two week period while trying to work it out. I thought I was going to have it stripped.

VGC , rebuilt DISA, rebuilt Vanos and lower transmission lines are next.
