Product review (5 stars): unbelievably easy fix, quiet your noisy door.
I can't believe after years of listening to a popping/banging/clunking noise when the refrigerator door opened which I assumed was "normal" that all I needed was a 7 dollar part.  I ordered it, and installed it in less then 5 minutes.  It took longer to empty the contents of the door for removal.  Easy easy easy!
1. Empty contents of door
2. Remove hinge cover on top of fridge.
3. I marked with a pen on the top fridge the exact position of hinge.
4. Unscrew hinge bolts with ratchet and socket.
5. Lift door off of lower post and set door on protected surface.
6. I used flat blade screw driver and popped old hinge bearing out.
7. Installed new bearing, making sure it is pushed in all the way, tap it in with screwdriver handle to be sure.
8.  Set door back onto lower post.
9. Screw to bolts back through top hinge, making sure hinge is lined up with your markings.
10. Put top cover back over hinge.
11. Open and close door, and enjoy the silence.
