Hi
Micha3l
I would ask Birds in the UK what they think. They have done MANY lsd installs. Or maybe Harold at HPA:

Also... all bearings have a number on the side of them. Most German bearings are made by
SKF in Schweinfurt, Germany (only 50km from Bamberg - where I live). Its the (im)famous wheel bearing factory, that the allies bombed in WWII. Anyway... every bearing has a number on the side of it... This number can be used as a refference - for wheel bearing dealers in the states. It is not that hard to get a bearing in the states. Perhaps BMW doesn't sell them... but any SKF (bearing)dealer in the USA can get you waht you need.
Maybe ask your shop IF they have the special KuKu tools for pulling apart bearings. IF they say WHAT... Then maybe find another shop.
Good Luck,
Dackel
