My driver door was sagging pretty good. So I got the "Help" door hinge pin kit from Oreilly auto. I will say it was a bigger pain than I was expecting. The old parts came off pretty easily. However, the 2 bushings than go in from the bottom up, were a major pain in the butt. Some how you have to hold them and pound them in without cracking the edges of the bushings. What I eventually did was put a small short screwdriver through the bushing and then through the hinge hole. That was enough to get it started. Getting a good swing with the hammer is another story. I ended up realizing that you get better access to a good swing if you walk around to the outside of the door and stand by the mirror to get a good up swing. The other challenging part is getting that dang spring back in. I ended up putting 3 zip ties on it, compressing it in a vise, and then cinch up the zip ties. Then I quickly and carefully put it in its home, and closed the door on it some, then cut the ties. This is the way 1Aauto showed it on youtube and it was a lifesaver. I don't think there's another way without the proper tools. Anyway, I believe 1Aauto has a couple videos on youtube of this hole process. Just be aware that the bushings are a bit fragile on the edges and will crack if you aren't carefull when hammering them in.
