Rear differential questions
99.5 A4 Q with 2.8. I have a bad seal on the front of my rear diff....right where the drive shaft attaches. My Bentley doesn't mention a rear differential. It looks like there is a case I could just take right off the differential.
Does that case share the same fluid as the entire diff?
I believe there's some screwy tool to loosen the fill plug. Is it this?

No I mean rear diff. On the front of the rear diff is a case that's bolted on. My bad seal is at the front of that case, right where the drive shaft connects.

The 'tamper-proof' drain on the gearbox is an XZN-type 16mm socket similar to the one shown in your link.
The procedure for replacing the differential front seal is in the Bentley shop manual.

Yea but it's odd that Bentley never mentions the rear diff. I think I found a technial bulletin on it....that's it. Weird.

Weird. I was looking under "5 Spd. Manual Transmission 01A All Wheel Drive". Group 39 has no rear differential. I gotta go to group 39 under "6-Spd Manual Transmission 01E". That group shows the final Diff.
My Bentley is on my hard drive...don't know if that makes a difference....
