I too have had this problem on my '98 Patriot. My doors are slightly shorter. I was going to have the welds re-welded, but decided on a very inexpensive but visible repair.
I carefully measured all of the tolerances then bored a few holes in the the door, of 8-32 size. I used stainless steel button head bolts (hex) I think, about 3/8" long. Don't remember the length for sure. To get the length, I used a tool to measure the depth. This is important because on the back side I put a nut with a built in star washer. Because of clearances the bolt must not protrude beyond the nut when tightened.
(What this repair did, was to hold the door skin to the back of the hinge). The bolts have not broken, but have worked loose over a 5 year time frame, so I just re-tightened them recently.
The bolts go just below the 3" black flange (on my Patriot) so the button head is almost touching the black flange.
If anyone wants to try this, let me know and I will e-mail a photo of what it looks like. It is really not that noticeable.
