The grill is held in using eleven clips and just snaps in place. Click figure 1 to see clip locations. Start removal by popping the top of grill (4 locations) loose using a large flat bladed screwdriver as shown in Figure 2 and Figure 3.
Next remove the two clips located near the headlights. You can do this using a screwdriver and prying against the headlight. I would recommend using a rag as show so you dont scratch the headlight. Do this on both sides. See Figure 4.
At this point you should be able to grab the grill with your hands and snap the remaing center and bottom clips loose and remove grill from truck.
Figure 5 shows the eleven clip locations.
