Door wouldn't close properly.

Removed top hinge cover. With nut driver, removed the three screws that held top hinge. Gently lifted door off bottom hinge and laid door across sawhorses. Once I saw what parts were worn on bottom hinge, removed them. Was a little confused from parts diagram online to what I had in my hand and needed to put back on door. After a few minutes realized I had ordered basically a duplicate part, "closer with cup", didn't need it. With a screw driver easily replaced new parts and reassembled the door. Works great.
