So I changed the top pin/bushings on my 94 S10 a year ago and it was a miracle.
Perfect level and like new again.

I did the same on my 2000 Blazer expecting the same result. Nope. No change.
Changed the lower pin/bushings the next day and got 50% better so at least the door will latch decent but it still visibly lifts about 1/8" - 1/4" when doing so on the latch side.
What else could be done to get the hinges back to new seeing as how it has all new pins and bushings and still has a slight sag?

 

did you check if the holes are egg shaped? if the hingle holes that the boshings seat into for the pins to go through are wallowed out, you will do little to nothing to fix it with just new crap.

here, this is from a project i had last year to make a helpful thread

Door does not latch properly/sags/feels sloppy on the hinges: You need new Pins and Bushings. Each door takes 2 sets (1upper and 1 lower). You can cut off the hinges and install replacement pieces. You can weld up the holes and ream them back out to size. Or you can try to use some JB weld or similar metal filled epoxy to fill the void and restore the hole. These are in order of complexity as well as permanence. With putting replacement hinges on as the most complex and the longest lasting option and using a metal filled epoxy as the easiest, but least permanent option. – swartlkk
