The driver's side door is sagging on my son's 1995 F150. Are there any tricks or suggestions on how to proceed in repairing ? Do I need to replace the hinges or just tight up the bolt/screw. Is this a common thing with an older F150. A buddy of mine has one and the same thing is happening to his as well. Any suggestions will be appreciated.
Correct me if I'm wrong, don't believe there is any adjustment available other than spring the door to lift it up. Place a small piece of wood like a 2 X 4 near lower hinge and close the door gently. If a change is noted then get a little more aggressive as needed.
No, not exactly, place the block of wood in the jam area or even at the bottom of the door and try to close it. The interference will not let you close the door because the wood is in the way. It will lift up on the door slightly, its actually springing the hinges to compensate for the sag. Years back when prepping new cars for delivery, that is how alignment was performed.
Don't do the 2x4 trick. While a good trick for a last resort, you need to fix the actual problem. The hinge pin bushings wear out, causing the door to sag. Usually the parts store has new pins and bushings right on the shelf. You will have to cut the old pin out and change the bushings, which just press in. Then install the new pin. If the bushings are completely gone then there may also be wear to the hinge, and replacing the pin in that case might not get rid of all the play. I've replaced the bushings and pin on a worn hinge and it still fixed the sag, but best to replace the whole hinge in that case. To see which hinge needs the bushings (it could be both) open the door and have someone lift and drop the door while you watch both hinges for play.
The replacement pins use a lock spring to keep from backing out and do not need the flange. Usually you have to pull the door off the hinges after removing the pins to properly replace the bushings as they have a flange that rides on the hinge that is attached to the body.
