2001 ford mustang door hinge ( with picture)

for some reason it wouldnt let me post a picture on my previous post!

when I lift my door it wobbles up and down and when i close it it sags. I have to slam and press the door for it to close. Im asking if i have to replace the door hinges or get the repair pin kit. and if i have to replace the hinges do i replace the lower hinge or upper or both
