After 15 years of service my doors and now clunking, rattle, wind noise etc. I've been pretty religious about keeping the hinges lubed up and checking for door sag. Actually, my issue was more so in the rear doors which the lower latch was a bit sloppy. I did a bit adjusting to align the striker pin in the middle of the latch gap and make sure the door made a full cycle in on the latch (both latches). Then you have to re-adjust your main door striker pin the same way middle of the latch notch and enough that you get a full cycle of both latches. This really tightens up the doors a bunch and seem to shut solid now and tight.
As for door sag, you can check this by having the door open and lifting at the outer bottom corner and seeing if the hinge moves at all. If it does that means you'll need to do a door hinge rebuild. Don' let this go it will ruin your door latch eventually because of misalignment of the striker pin beating the top of the latch.
