OK...I have a gen 1 (2007) and don't have one. Looks like you have been pulling on the wire cable coming out of that device too... Force isn't good on electrical stuff.

Manual said remove wheels, you understand that means the axles have to come out of the front wheel bearings, first thing? If so then your picture showing the outer half axle (which is inside wheel bearing) is still attached to the mid shaft...So if axle is out of wheel bearing it is removed first before you loosen the pillow block (middle support) mount. Then you remove the middle shaft straight out of the transmission...You currently show both still in one piece. See my pictures shows no widget on block near mid support, and even if I did you would still have to remove outer axle, then middle support, then pull out of transmission.
