Ohh ok, but see read carefully. It is ONLY the housing. So that should mean there are no axle shafts, r&p, etc. You can buy an empty D44 housing for 600-700 bucks from the dealer, but you'll have to add a carrier, ring and pinion, and shafts etc. 400 is discounted, but it won't be a complete "working" bolt in so to speak.
