RHF Upper Hinge Differences
(Note that upper hinges for the Right door are stamped LS; left-side hinges are stamped RS.)
The F-series & Bronco lower hinges are identical (reversible), and did not change from '80-96 (& '97 >8500GVWR).
Early upper hinges use an S-spring rod & an indexed roller wheel that must be greased frequently (and turned manually occasionally) to avoid noise. Later hinges use a larger roller & flat band spring with rubber reinforcement, but the band is known to crack. If it does,
HELP 38435 is one way to fix it.
To install a hinge & align the door, read the other captions in this album.
