Actually that is true, most door pins either have a small pinch at the bottom, or a circlip, or in fords case, they have little teeth at the top of the pin just to give it a minimal amount of bite, so they wont work their way up, or fall out if you enter it in a tough truck competition.
I think you are right, from waht I remembered from this morning, I can probably knock the pin out using a hammer to seperate the hinges, but I need the hinges off to re-drill it to accomidate the bushing, and a 5/16th bolt, and the old size looks like its a bit too small to just hammer it in.
Brass bushings seem to do well in this application, usually OEM setups use brass or plastic, in our maximas case, its plastic, which got chewed through
I finally found the pic of my problem, Its this thing that I have problems with, I dont wanna hurt the pin by cutting or hammering it out, cause I dont think I can find a professional looking replacement
