I just went into Napa auto parts and ask for a hinge repair kit for a '97PSD and I walked out with two (2) in hand at $5.00 a copy.
They are a piece if cake to install. The kit contains 2 bronze bushings an "E" clip and a pin with two (2) groves for the "E" clip depending on the height of the hinge.
I took a dremal tool and ground off the top of the OEM pin, then took a long sender punch and drove the pin out.
Now is the time to have a helper. I placed a bench beneath the door and built it up with moving blankets. Have the helper start lowering and moving the door away from the other part of the hinge. (Hopefully you have removed the punch)
On the
DOOR SIDE ONLY scribe around the that part of the hinge so you can replace it exactly where it was originally. remove the two 12mm bolts and you now have the inner part of the hinge in your hand and it contains the bushings.
Carefully drive out the bushings, take the new bushings, I found it helpful to put a slight taper on the edge of the bushing, it just starts better.
Drive/press the bushings into the hinge, now, make sure that the pin slides in smoothly. If it does, replace the hinge on the door, Aline the two parts of the hinge up and slide the pin into place. The pin needs to be driven approximately 1/4" into the hinge to seat it.
Slide the "E" clip on after picking it up from the floor several times
and viola. Your done.
I only changed the top drivers door pin as it was the only one that sagged.
