Door sag

[jdheff1982]

Hey all,

The doors on my truck are sagging a bit. Would a hinge pin kit resolve this or will I need to get new hinges all around? Thanks.

hard to say without seeing the truck but more often than not you can replace the pins and bushings and it will work out fine

Rotted cab mounts will make the doors sag too. If it's just loose hinges new pins will do it. No need to replace whole hinges.

If it's not a rust issue....Open your door all the way and pick up the door from the outside and move up and down..if it only moves at the pins replace pins

If the whole hinge moves you got bigger problems.....

Also check your doors for cracks around the spot where the door is bolted to the hinge.

No, both doors move at the pins. That is good news, LMC only carries the upper hinge for 1 door.

Good go get some hinge kits and call it done

When you say the doors move at the pins, do you mean that you can open the door, grab hold of the outer edge, and move the door up and down? If so, and the hinges are secure in the door and cab, then you need new hinge pins. You should be able to look at the bushings around the hinge pins and see that they are worn out. If you replace hinge pins and bushings use only GM OEM parts. You can search my username on this forum for hinge pins and see two theads - one for my failed attempt to use aftermarket (Dorman) hinge pins and one for my successful attempt to use GM OEM hinge pins (with pics.)

I just put the dorman pins in my 85 and could not be happier. It gets a little more involved than you think. You need:

-Cut off wheel on a 4 inch grinder.
-indexed drill bits.
-Hammer and punch.
-vice.

I left the brackets on the cab and removed the door. Then I cut the original pins with the cut off wheel. That lets the door side of the bracket come off.

Next I put the bracket in a vice and punched out the remaining pins and plastic bushings with a punch and hammer.

Then you find the appropriate diameter indexed drill bits to enlarge the holes on both bracket pieces.

After everything is drilled out you pound in the bushings, pound in the the pin and bolt on the door. The most time consuming part is getting the door lined up again.

This sounds good. I am unfamiliar with indexed drill bits. Are they different from normal bits? Also, I will prolly just pull the hinges off completely and try to remove the pins with them mounted to a table-top vice.

This will give me something to do next week.
