On my 03 4 door SC the rubber trim thing (on the rear door ~3ft. long along the whole edge of the door) that seals the 2 doors has fallen off. I can put it back on but it does not stay... I've had not problems with the driver side but cannot tell how it is affixed (no external clips or anything). I assume that there is some kind of adhesive ??? IF so what kind would you guys recommend?

 

I would try some basic clear RTV. Just make sure the seal and where it attaches to the truck is cleaned throughly.

 

Beauty on the RTV.. I had the same problem with my 01'. RTV took care of it and hasn't fallen since!!

 

Just run the length with a pair of pliers. There,s a thin strip of metal inside that,s bent in a u shape. Just squeeze it back together.

 

I did the same as Tex on my 03 and 02. Just lightly crimp it.
