1998 T&C Pass window keeps falling off track

My 1998 T&C has a problem where the front passenger window keeps falling off the track (caused by hard slamming of the door).

I've gone into the door multiple times to pop the rear-most peg back into the white plastic window track "dog", but it keeps popping out after moderate door slams. Do the black pegs that are glued to the window wear out? (I think they're metal).

I think the plastic track dog is fine, and I make sure the metal clip is fully engaged with the window peg each time I pop it back in. The only reason I can come up with for this problem is that the window peg is worn down and has lost its "edge" and thus the metal clips can no longer retain it. Sound reasonable? Probably need a new window from junkyard correct?

I've done a few of these but have never had your problem. I take it the metal retainer clip is popping off too. Has it opened up a bit too far? I would take a very close look and compare the front peg and clip to the aft to see just how worn the aft is if at all. Can you see if the track is bent or damaged in any way? May need to remove the whole shabang to get a good look.

Not positive but pretty sure you have to replace the window if the peg is trashed unless you can make some kind of backyard fix on it.
