Hi Dave
its common on a shogun if not oiled, its a pain in the ar$e to get the pin out without destroying the hinge so i would bin it,
best bet is to find a good one at the scrapys paj/shoggys theres loads of them, drill a hole to the pin through the side and tap a thread in it and put a grease nipple on which a lot of pajero owners have done to stop them creaking and groaning.
