Unplug your refrigerator.
Open the doors of your refrigerator, and remove all door bins and any food in the bins. Turn off your refrigerator and freezer via the controls in the unit.
Remove the screws holding the hinge cap in place with a Phillips screwdriver. Remove the cover to expose the hinge and bolts. If there is no cap covering the door hinge on your particular model fridge, you may skip this step.
Remove the hinge bolts with your wrench. Remove the metal hinge from the door.
Open the door, lift it up and place it on a sturdy work surface. Locate the hinge bearing on the corner of the door, inside the door stop bracket.
Insert the tip of your flat-head screwdriver in the slots in the bearing. Pry up to pop the bearing out of the compartment.
Fit a new bearing in the compartment and snap it in place.
Replace the door, hinge, bolts and hinge cover.
