Installed this weekend and it is working great.  There is a u-tube video where they put a board under the door, and work on it in place.  But working on the bottom of the door, in place is difficult and maybe even dangerous.  I removed the door bins before starting.  The door isn't heavy when empty.  I removed the top hinge and lifted the door off the bottom hinge.  No need to remove the bottom hinge.  You need a 5/16 nut driver, not screw drivers.  I used a magnetic driver in a cordless Mikita. Super quick.  Lay the door on its side to get at that cam, from a comfortable position instead of laying on your back on the floor.
 The screw holes in the plastic cams are larger then my originals parts.  Note that two of the new screws have a wide shaft just under the head that fits the holes.
Be careful to get the upper, door side, cam lined up hole in the door bottom so it cam all drop back on the hinge pin. The closing force gets stonger after you put all the bins and their contents back in the door.
