Sorry about that. The second link (the one that sums up the TSB) was supposed to link here:
http://volvospeed.com/Repair/AWD_bevelgear_diff_service.html

This is to actually install a drain in the bevel gear so that the oil will run out of it and not have to be 'suctioned' out (which is a pretty bad way of changing fluid in a gearbox but sometimes the only way...)

There is already a 'vent' in the bevel gear, though it does sometimes get clogged - this can lead to problems too, and I think there is also a TSB related to installing some hardware in the vent hole to improve it's performance and resistance to clogging, but nobody ever does this because it requires removing the BG from the car, which takes a long time and costs lots of money and is therefore not usually worth the bother. If your BG is leaking this might be the problem though.

Anyway, that bay13 link will show you how to install the drain. I did exactly that to mine and it worked great. I believe KlausC did the same.
