Hey Erude73... I literally just had the same thing happen to me. Snapped right in the same spot yours did all around the bearing. What have you come up with for a solution for this problem? I have no idea how to get this housing out and I can't find anything online as well.
you have to remove lower carrier plug, shaft, then take off the pinion nut and it all comes out. requires total strip down. new housing come with a bearing so no need to order one.
