i am in the process of changing all the fluid , and i am down to the front diff , went to dealer to get pan gasket as there is no drain , and they couldnt find the part i was looking for they ordered me the oil pan gasket,
I go pickup the parts and i TOLD them it was wrong and ! guy walked away from me ( the guy who ordered the part and i had to talk to another guy , wtf , ) i go home with wrong part in hand and verify( wrong!!!!part?)
they couldnt even find the front diff cover , they do show me that the front diff is incorporated into the block, and is actually part of the "oil pan" just a little FYI for 4 matic owners out there .
