All bolts are easy to get to and pretty obvious, but, if the fender has never been off before, you'll have to grind the tack weld at the wiper cowel in order to remove the fender, so beware not to wreck it pulling it off.
I never grind that tack weld. It is very weak. If you pull the fender up about an inch and move it back and forth about 6 inches about a dozen times the tack weld will fatigue and break without distorting the fender.
Adjusting the door hinges isn't difficult without removing the metal fender. Replacing the door hinge bushing is. You can't get to all the bolts holding the hinges on to the door from inside the fender. I remove the entire door while leaving the fender on. 6 bolts hold the door on. After removing those 6 bolts I walk back and pull the door handle, releasing the door from the striker and carefully lowering it to the ground. From there I remove the other 6 bolts that hold the door hinges to the door itself.
It is very common for several of the bolts to break. Make sure you take all the bolts to a wire wheel while they are removed and use "never-sieze" before installing them. The bolts thread into a plate of metal inside the body of the car. Those plates can actually be removed if you push them up and over the slot they sit in. From there you can take them to a vice and drill the hole out to repair them.
I replace the hinge bushings in a vice making sure to use copious amounts of "never sieze" on the bushings. Never sieze works great as a substitute for white lithium grease. I use it on all squeak prone areas including hinge pins, bushings, and all rubber bushings (it especially makes a huge difference if you coat both sides of any polyurethane bushings, those are extremely prone to squeaks).
After I replace the bushings I bolt them back on to the door. This can be tricky since the door has backing plates in it as well. It is possible to hinge bind the door by bolting the hinges back on to the door crooked. I eyeball the hinges as I bolt them back on to make sure that they are in as close to the same spot as I removed them and that most importantly the hinges are inline to each other. A straight edge across the inward face of both hinges may be necessary to make sure they are square to the same pivot axis. Ideally you will outline the hinge with a shot of spray paint before removal.
At this point I put the door back up with the door hinges behind the fender and the door striker clicked into place. The door striker will hold the door up while you reach through the fender and bolt the 6 bolts into the body. The plate the bolts thread to can move and pivot, so it can be tricky to the get the bolts started. I usually use a punch in one or two other holes to align the plate while I thread the first bolt in. Since I wire wheel and exercise all bolts before reinstalling them, they thread in easily by hand. I snug them up as tight as I can with my fingers.
I then adjust the door by opening the door about 6 inches. A second person will hold the door up as far as they can hold it, which will be about 2 inches higher than it should sit. At the same time I use a pry bar or big screwdriver to push the bottom of the door up at the very corner nearest the fender. Sometimes I need to use the same screwdriver to open up the space between the door and the fender momentarily, before putting it back at the bottom of the door. As I hold the screwdriver at the bottom of the front corner of the door with one hand I reach inside the fender with the other hand and tighten the 6 bolts for the hinges. After the assistant lets go of the door it will sink about 2 inches and rest near the correct height. It usually takes two or three attempts to get it exactly right.
The end product should have the body line on the door perfectly inline to the one on the body. The best body line to look at in evaluating your door adjustment is directly above the paddle door handle, about four inches below the window.
After aligning the body lines I then finish the job by adjusting the door striker. It uses a size 55 torx bit to loosen. I look across the opening in the door to align the striker vertically, then push it as far inward as it will go back horizontally before sliding it forward about a quarter of an inch. A few slams of the door will tell you if it needs to go further in or out. If its too far in the door will not fully latch without an obnoxious slam. Too far out and the door seals will not seal correctly and the door will jiggle and rattle going down the road.
