Door would not close properly

I emptied everything from door compartments.I removed the top cover of the door pivot with a phillips screwdriver. I removed the two screws that that hold the pivot bracket with a 8 mm socket. Lift the door off the bottom pivot bracket. Remove the old bottom pivot bracket with an 8mm socket and replace it with the new cam bushings.You must replace both bushings on the bottom of the door and on the bracket that mounts to the base of the body of the refrigerator. Reinstall the door and screws .The doors should be level with each other if they are installed properly.If not check the freezer door .The bushings may be worn on that door also.
