If your door is sagging that you can't close it properly, this which could be a result of worn pivot pin hinge. My 2000 maxima had this issue and here is how I fix mine.

1. Get two 1/16" thick 1/4" bolt washers.
2. Cut the section of the washer to make "C"

3. Remove the bottom nut of the bottom hinge that hold the hinge to the door. Swing the door all the way open and use 12mm wrench.

4. On flat ground, Using floor jack, lift the edge of the door to expose the gap between the hinge and the door. DO NOT over do this or you will bend the hinge and WILL make it worse.


5. Once you can see the gap between the hinge plate and the door, use big screw driver to pry it open SLOWLY. The gap on my hinge plate to the door surface is about 1/8", yours maybe different depending on the severity. Just remember to not over due. With the tip of the screw driver wedge in the gap, insert the 2 washers. Position the washer slot pointing down as much as you can to minimize the chance of it's falling off. You might need to use hammer to aid inserting the washers. Use safety glasses and make sure your floor jack is secured

6. Replace the nut, torque it to spec, remove the floor jack, and you are done.

 

Damn, I gotta look into this when I go home. I do have this problem. Do you think the wedge is good enough or should you put something sticky on the washers to make sure they dont fall out



And remember to put something under your door so the jack doesnt scratch it guys

 

When I inserted the washers, they are pretty tight that's why I had to use the hammer to push the washer in. Once the washers are in, they will stay there, especially when you torque them good.

Oh ya, thanks for the reminder to put something under the door.

 

Gotta do this, too.
What's the correct torque spec for that nut?
