Congratulations on getting the fill plug out.


Does your Differential look worse than this?

Yay, success! I used a bit of WD40, left it for a day, then got a proper good quality socket, which did the job. But man, it was tight!

However, when I removed the plug, to my surprise I found out there was too much oil, as it started leaking out. I drained about 50ml of the old oil. Actually, I have a bit of leak through the seal on the left hand side of the diff, so maybe that was the reason.

Thanks everyone for the suggestions!

Now I will just do the proper oil change.

I had a similar experience with a weep of diff fluid from the output oil seal, but every time i checked the fluid level more was coming out. Turned out to be Haldex to diff seal that was poorly seated. 2005 D3 2.7 Auto

Mine definitely weeps a little on the fill side (as you can see from the picture) and its significantly cleaner on the far side.

The leak rate is so slow that I don't add any fluid between changes every 50,000 miles.

Post a picture of your diff if you get a chance.

I already cleaned some of the oil leak. May not be so apparent in the picture, but it was obvious the leak was originating in the left hub. I will see how I go that there is now the correct amount of oil.

^^^^^ Maybe it's this part? Some refer to is as a ring or gasket, LR030846.

I assume that we are talking about this seal
