Product review (5 stars): BUY BOTH TOP & BOTTOM PARTS!!! 240457702 & 240328203
You will want to replace both parts (Electrolux 240457702 Closing Cam & Frigidaire 240328203 Hinge Bearing ) together, so order them together.  If one part becomes worn down over time (for me it was about 8 years of use), the other part will need to be replaced as well.  In fact, while you have the tools out (only a philips screw driver and ratchet set required), you should probably order 2 of each and replace both the top hinge bearing that fits in the door and bottom cam that attaches to the hinge on both doors, the refrigerator and freezer sides.  This will make your doors open as if they were brand new again, and this is one of the simplest DIY projects you can do.  If you have frige doors that are squeaking, jumping, bouncing, or just not closing properly, these two items are amazing, cost effective at around $23 total for the two pieces, and they will solve your problem.  I also wanted to add that these work properly with Kenmore Refrigerator Model No: 253.53673302, Serial No.: LA31601471, MFG: 04-03.  I expect these will last another 8 years with normal use. Good luck:)
