I am thinking there's a split in the boot, and where it's opened the grease is coming out. When it spins the centrifugal force throws the grease out. Eventually an open boot covering an axle with no grease would get water and dirt and whatever else inside and corrode. Didn't even think about the grease itself as corroding, so no I didn't think you were asking that
