So the other day I was at a job and I saw some oil dripping from bottom side of the DMax. I crawled up under the truck and first noticed the rear differential leaking. I figured it was a simple fix but then I looked a little further and realized that there was a shine on the front of the fuel tank. The transfer case was leaking. I took it to the dealer and they found that the pump had worn a hole in the side of the transfer case! This is a known problem apparently but GM won't recall it. Oh well, guess I'm stuck paying the $2100 bill. Just wanted to vent a little, its been the only major issue on the truck so far...knock on wood.
