I know about that part; I was picturing him routing the copper tubing inside along the axle housing, parallel to the axle instead of directly up to the top of the diff housing. Probably a terminology thing - I consider the part where the diff bolts as the diff housing and the long parts on either side as the axle housing. I could see how you could call the whole thing the axle housing as it really is all one piece.
