Question about Differential bearing oil sealing rings

So, in the process of welding up that small rust spot under the rear seat....

i found that the bearing of the left output shaft of my differential died: the cage spacing the balls evenly split in two, leaving a metal shard to eat up the inner bearing ring surface. Luckily the shard stayed inside the bearing, and didn't wander off to the internals of the diff. This also explains the slight hesistation i felt when rotating the input shaft.

So I'm up for new bearings and oil seals.
Bearings I managed to source locally, they are standard components (type designation 16006A, original brand = FAG)

However, visiting my local BMW dealer; i find that he can't provide the Reperatursatz (repairkit) for the diff, indicated in my books as (old p.n.= 33101203953 and new partnumber=331012030010), containing the 3 bearingseals, o-ring and oil plugs.

Help wanted: What partnumber should be the right one for the sealing kit indicated in 33/14/2?

pic of the broken bearing to follow later, adding attachments doesn't seem to work just now.

regards,

pics of things that could make a diff sound unhealty.

1. 2 pics of the broken bearing cage; inside the diff the balls remained in place, but once the oil seal was remoed, the rings en balls came rolling out.
2. Finally we have proof, I have found a UFO !
It's a metal flake that found inside the diff. No idea where this is coming from. It seems to be stainless steel, although its very, very thin. Perhaps a piece of (zinc) coating? Or it travelled at warp speed directly from comet 67P/Churyumov/Gerasimenko....
3. The internals spilled out when I detached the front nut....And i want to check if the UFO was not part of a vital component; ready to give up the fight during the first test drive.:neutral:
4. Pic with diff in the vice, to ensure easy grip. I used a 3 ft (1 meter) piece of steel bolted to the flange to stop the driving flange from rotating when removing the large nut & 2 bolts attaching the 3 flanges.

Use a gun for those bolts. Try buying individual parts instead of the kit.
Don't forget the big oring!
