The plastic sleeve insert in the bushing on my car disintegrated and I
relaced the whole upper hinge on the driverside on my 91 Bonneville a
few years back. Got a hinge off one from a junk yard car that had very
little wear. I got it installed & lined up pretty close myself, then
took it to a body shop for a final adjustment.
The door latch wasn't hitting the striker on the center post properly.
The striker on my car is non adjustable.
The body shop had these eight foot long pry bars and slide hammer and
one hell of a sledge hammer to knock the hinge back into alignment.
The guys at the body shop couldn't believe how close I got by using jus
two hands, then I told them - I didn't loosen the lower hinge when I
installed it, I sprung the door slightly out from the upper hinge, then
slid the replacement upper hinge in where I put a line up mark then
bolted it down.
