2003 Superduty Doors Won't Latch

[wowchad]

Has anybody else had a problem with the painted door latches not staying closed?
I had it into the dealer for repair and they told me the put in "super special lube" and it should be fine. Well the next week my wife had it loaded full of people and the door flew open on the freeway.

The problem is on both the drivers and passenger doors. It's never happened on my 2000 F-350 but those latches are black and my handles on the 2003 are painted.

I will not return to that dealer but until I can get to a different one I need a quick fix so I can use my EX this weekend...anybody have a suggestion?

Look at where the door latches up. I think something is out of adjustment.
Feel how hard you have to slam it to latch. If to tight loosen it and move it slightly and retighten. Any body shop can do this for you quickly. I doubt if you got two defective latches but it is possible.
