Thanks for your thoughts on this.
I noticed the problem with both front doors before the panels were reinstalled, so They are not installed wrong.
The long rod does not appear bent on either side, I moved the rod at the latch, and it does not travel like the old latch did, so I doubt that they are bent at all and do not appear to bind anywhere along thier length.
I'm not in a cold area, quit the opposite I live in the Nevada desert, and it gets very hot here. I have always used white lithium grease for this.
Like I said the rear doors are working fine, I got those latches from a different seller, and I believe they are a different brand, and they are working fine.
If it is determined that the latches are faulty then I will need to buy from a different source and the prices per door vary between $30 each to over $200 each door depending on where they are purchased.
In the past I would have just spent the money and purchased Dorman parts for this but I am doing both of my trucks at the same time as well as replacing the window regulator & motors along with doing a full brake job, tranny service on both trucks, fixing steering issues and replacing axle seals. It all hit at the same time.
