A single bolt hold the door handle assembly onto the door. The bolt is removed and the linkage rod is unclipped and removed. The handle is then removed from the door.
The plastic moisture barrier is carefully peeled off from the door (see green arrows below). This barrier must be retained and reinstalled at the jobs completion. This barrier keeps water from ruining things inside of the truck and also serves to cut wind and road noise.
The door lock linkage rod runs from the knob we previously removed to the door latch (blue arrow). Even though this rod is bent like a pretzel, it only moves horizontally as shown by the red arrows.
