Regarding the &quot;heat treatment&quot; I believe that was only for the Ring and Pinion, not the carrier.

While the carrier was different and some special parts were used, I don't recall anything other than the Ring and Pinion getting anything special heat treatment wise.

For future searches, here are all the BE KQ goodies that allot of the BE's are lacking.
The carrier is a standard 4 series and is machined differently inside.
