Product review (3 stars): Loose screws or bad cams?
I ordered the 4318165 door closer kit because the refrigerator and freezer doors both made loud pops when opened and closed on my Whirlpool Gold Model GS6NBEXRL01 side-by-side refrigerator/freezer which was manufactured in January 2006.  We have probably had it since 2006/7.  I removed the water filter and the kick plate.  After emptying the refrigerator door of food, I removed the upper hinge and then lifted the door off the bottom hinge. There did not appear to be a lot of wear on the upper or lower cam and neither had any cracks.  I replaced the upper cam and screw that were attached to the bottom of the door from the kit without any problems.  Then I began to replace the lower cam although I could not distinguish between the cam provided loosely in the kit bag and the cam contained in its individual bag within the kit bag that was labeled 2182132.  I decided to use the unlabeled cam.  HOWEVER, I did notice when removing the lower cam that the screw retaining the cam was loose and that the cam could be moved slightly.  I replaced the cam and the new screw from the kit.  I also lubricated both cams with a synthetic lubricant.  I rehung the door and reattached the upper hinge.  When I opened and closed the door, the popping sound was GONE!

Then, I removed food from the freezer door.  I removed the upper hinge and found that my refrigerator/freezer had no wiring at the upper hinge like that I had seen on a Youtube video.  I disconnected the water line at the lower hinge and two electrical connectors that also passed through the lower hinge.  While my wife guided the water line and electrical cable, I lifted the door off the lower hinge.  Here I discovered a MAJOR problem!  The openings in the upper and lower cam for my freezer door were much larger than those of any cams supplied in the kit.  There did not seem to be a great deal of wear on either cam and there were no cracks.  BUT, I did discover that the screw holding the lower cam was loose and that the cam could be moved slightly like that on the refrigerator door.  Since I did not have the proper cams, I tightened the loose screw, lubed the cams, replaced the door (with my wife guiding the water line and electrical cable through the lower hinge, and reattached the upper hinge.  When I opened and closed the door, there was NO popping!

So, I'm not sure I really need this kit at all.  I certainly did not for the freezer door.  If you check your cams and find that they look to be in pretty good shape and that the screw holding the cam is not tight, then you may not need this kit to get rid of popping noises when opening or closing your doors.  On the other hand, the kit is fairly cheap and if you remove the door and find your cams badly worn or cracked then it would be nice to have the cams on hand to complete the repair at that time.  However, this kit did NOT contain the cams required for my freezer door.
