The upper and lower shaft are held in position by two plastic "shear" pins. When forced to collapse they "shear" and allow the shaft to absorb the impact. To repair, remove the visible pieces of the shear pins. As you re-extend the shaft, put a sharp pick into the hole and you will feel the inner hole. You now have the original alignment. I install a small sheet metal screw into the hole to lock it in place. Straighten the outer housing and you are done.
