Replacing Door Hinges

  After 15+ years of use, most driver side doors are beginning 
    to sag. To see how bad your door is sagging, open the drivers side door about 
    8-10 inches, and lift up on the end of it. If it deflects any, then the door 
    is sagging. Compare it to the passenger's door, which shouldn't be near as 
    bad. 
  Door Hinges Part #s: 
 
  1) Open the door all the way and place a floor jack (with padding 
    to protect door) under the center of the door. 
  2) Remove pin that holds on the "brass colored lever thing in 
    the middle that keeps the door from opening too far". Use pliers to close 
    leafs at bottom of pin while pushing up though hole. 
  
   
  3) Remove 4 (12mm) bolts that hold door to hinges. It would 
    be helpful to have someone to help balance the door on the jack, but it is 
    doable alone (I did it alone). I had to used a 1/4" drive ratchet because 
    I couldn't fit anything bigger. PB Blaster and a 36" long pipe (cheater bar 
    on ratchet) were needed to "persuade" the bolts to come loose. 
  
   
  4) Slide door on jack away from car. 
  5) Without the door on, mark the location of the hinge, so that 
    installation is easier. You can get to the 4 (12mm) bolts that hold the hinge 
    to the body without removing the fender or any fender bolts. I was able to 
    fit the 1/4" drive ratchet to loosen two of the bolts. The other two require 
    a wrench (non-offset works fine). PB Blaster was again helpful. 
  6) Remove hinges and clean off the old silicone/caulking that 
    was around the hinges. 
  7) Put new hinges on in the same position as original and tighten 
    bolts. 
  8) Roll door on jack into position and put bolts in. This step 
    requires help to get door into position.
   9) Put middle lever back in and slide pin back into place. 
  
  10) Check door operation. Mine was still low. You cannot get 
    to the hinge-to-body bolt with door on, so you either have to remove fender 
    or door to adjust door position. I figured since I just had the door off, 
    it would be easier to remove those 4 bolts again instead of removing fender. 
    I removed the door, and tilted the bottom hinge up. When I tried putting the 
    door back on, it would not line up with the bottom hinge (it was tilted too 
    much). Adjust the bottom hinge back down a little, and put the door back on. 
    Fixed the problem. Door closes perfectly now. 
  11) I then adjusted my striker plate to raise the closed door 
    position slightly (to get a tighter seal with the window closed).
