04 V6 4runner. Found a pair of oily breather tubes on driver side, next to engine oil filter housing. Dripped Oil stained LCA. They seem to root to front and center differential, but I am not too sure. Is this caused by overfill of differential oil?
Just had front diff oil drain and filled when CV axle was replaced. The mechanic probably put over 1.5qt in it. I did the center diff oil change, put in less than 1.4 qt when it overflows.
