fighting with this diff fluid leak from what seems like the rear cover. i did the output shaft seals a while back and then re-sealed the rear cover as it was leaking also. well now the rear cover is wet again. hard to tell exactly where its coming from as the air flow under the car blows it all around. the only thing i can think of is the orientation of the oil passages in the flanges that bolt to the case. i marked them before i removed them to replace the seals and put them back exactly how they came out. however there seems to be some confusion as to exactly which way they should sit in the diff. mine are above the oil level. if you were looking at the right side the oil passage would be right around the 10 o'clock position and the left around the 2 o'clock position. according to this diy, http://www.m5board.com/vbulletin/e3...erential-side-axle-seal-replacement-pics.html they are not in the right positions though im pretty sure the diff was never touched till i wrenched on it and i marked the orientation of the flanges and put them back exactly how they were. seems a bit odd as why would there be an oil passage above the fluid level inside the diff? has anyone ran into an issue like this?
