I have been trying to figure out how the drive shaft flange comes out of the rear differential, because is doesn't appear to have a center 6mm allen bolt, like the side axle flanges have. Any help or diys on the rear dif seals would be appreciated!

Have you physically removed the drive shaft from the flange? Because there is a bolt in the midle to hold the shaft.

Yea i have removed the drive shaft from the flange. There didn't appear to be a center bolt holding the flange shaft to the rear diff. Your saying there is supposed to be one?

I'm not sure, but it could be like the front axle flanges on the 01A/012. The flanges are just pressed in. Just use two long bolts the same pitch and thread as the drive shaft bolts and thread them into the flange. Alternate back and forth, tightening them until the flange comes out of the diff. It's simple, just time consuming.

Interesting, so if it is just pressed in on my 01 b5 a4 mt, then is it hard to press back in after changing the seal?

If it's the same as the axle flanges - I used a long jack handle 3-4' with a rag on the end and hit it with a rubber hammer to drive the flange back in.

I ended up getting the diff extension taken apart. I ended up unbolting the extension, pulling the knuckle off the end. I then removed the circular plastic plug and unclipped the c-clamp around the flange shaft. From there the two bolts alternating back and forth trick worked nicely and the whole flange shaft came out. Thanks for the input guys and sorry for the long wait on replying, been working overtime at my job.

Glad it worked out!
