So my driver door sags when it is opened and I think it is getting worse. Is the proper course of action to replace the pins holding the door on? If so, where do I acquire said pins? Also, the top pin sits above the spring so I am not sure the best course of action for removing the pin. Pleas help! Thanks.

 

There are a few threads here on this. Harbor Freight has Spring compressor & any parts house has pins & bushings. Do a search your find step by step instructions & links to tool,
