Hello all, I'm new to the forum & just purchased an '07 Xterra with a 6 speed manual & only 42,000 miles. Its a beautiful truck, very clean body & interior, but there is a strong odor of gear oil in the cabin. There are no leaks or drips anywhere + it drives very tight with no squeaks or rattles. Any ideas of where this odor is coming from? I first thought the previous owner over-oiled the seat tracks, but that's not it. The smell is just too strong.
