Diff oil is still good, trans got done at 100 000 km (drop pan, change filter). Oil just got done also before I bought it. The guy was from the military. He was keeping things real tight. Like he said, ''I dont' F*** around''.
I almost bought a Titan, but after reading about it, I strolled away from it. Also, people told me to stay away from it.
Alltho, I think I will get the diff done just to be on the safe side. Thanks for the heads up on the fluids!
