LSD e34 parts to e39

[dovlet]

Dear Friends,

Today I realized that mine reducer is not LSD 3.15. Long story I will just skip it. So, found LSD 3.91 for e34. I have long reducer from e38 7 series (large) which is 3.15. Can I take insert of e34 3.91 LSD and put in to e38 3.15 reducer?

Sorry for my English.

Dov - "differential" is what we call it (reducer is russian translation?)

I've never heard of anybody putting E34 internals into an E38 or E39 case. Have no idea if its possible. I do know on the older cars there are issues with different case sizes and compatibility - there are 'medium' and 'large' case diffs. But I don't really know that much about it, again never heard of it being done.

Well, that's one of the things a diff does: reduce, or gear down, the rotation.

Yes, differential
