current workhorse issues

[heeroyue2002]

hi need some help with an issue on my 94 astro van. didnt know where i could post it. its basically got a truck frame and drivetrain right. well heres the deal. the door hangs a little and it makes it hard to pull it open so ive broken the handle a couple times. ive gotten another replacement but id like to make it stop hanging, im getting tired of jumping the seats to open it. someone told me i can replace the bushings on the door? i dont even know how to pop the door off. i tried to on a junkyard one and it was a FAIL. thanks, im including some pictures.

Door closed


door hanging. u can see it better on top part.


inside door, bushings and removal are here??
