How to remove the plastic front bumper.
Remove the grille
The top edge of the bumper is held by five of the same plastic pins that hold the top edge of the grille. Remove 2 of these on each side, leaving the center pin in place for now.
On each side, remove the 4 Phillips-head screws that attach the bumper to the plastic fender well liner. Two of these are on the bottom edge of the bumper, and two are on the edge along the wheel well. If you haven't removed the tires, it may help to turn the wheels to make access easier.
In this photo, the locations of these 4 screws are marked by the blue arrows:
Starting at the bottom, ease the plastic fender well liner out past the edge of the bumper, up as far as the top edge of the bumper. Using a screwdriver, putty knife, or prybar may help with this. Make sure not to lose any of the clips that the hold the screws removed in Step 3.
Remove the 10mm bolt that holds the rear end of the bumper's side wings. This photo shows the plastic fender well liner out past the edge of the bumper, with a nut driver on the 10mm bolt:
The bumper wings will now 'snap out'.
Once out, it is a good idea to cover them with a rag, to prevent them from scratching the paint on the fenders.
The bumper wings are held in two places.
The photo in Step 3 shows these locations with yellow arrows.
The photo below shows the location of the 10mm bolt removed in Step 5 (white arrow), and the two places where the bumper wing is held by plastic clips (blue arrows):
In this photo the Phillips screwdriver is pointing to the clip under the headlight:
The clip that holds the corner of the bumper wing looks like this when removed (driver's side, viewed from above):
The blue arrow in the photo above shows the tab on this clip that holds the bumper wing.
You do not have to remove this clip to remove the bumper.
You can remove the two screws that hold this clip, and remove the clip along with the bumper:
Here is another view, from above (passenger side), of the locations of the two clips (yellow arrows) and 10mm bolt (white arrow) that hold the bumper wing:
If there are no factory fog lights installed, go to Step 11.
Remove the center pin that was not removed in Step 2.
Tilt the top edge of the bumper forward far enough to be able to remove the factory fog light wiring harness at the fog lights.
You can use a flat blade screwdriver, and press the center of the connector clip towards the rear, and down, to release the connector from the fog lamp.
Tilt the bumper back, and replace the center pin that was removed in Step 8.
Remove the four 10mm bolts holding the bottom of the bumper to the front skid plate.
There is one on each side, and two in the middle that are accessed through holes in part of the plastic bumper.
Do not remove the five 10mm bolts that hold the two parts of the plastic bumper together - these 5 bolts are recessed in countersunk holes in the plastic bumper.
This photo shows the four 10mm bolts to be removed (red arrows):
The locations of the 5 bolts that do not need to be removed are shown with white arrows (the bolts are removed in this photo).
The blue arrows show the location of 2 of the 4 (per side) Phillips-head screws that hold the fender liner to the bumper.
Remove the center pin (that was not removed in Step 2, or was reinstalled in Step 10).
Remove the bumper, including the fog lights and if installed, the front license plate holder. Here's a photo showing the bumper, and most of it's attachment points:
white arrows = holes for 10mm bolts
yellow arrows = tabs where the bumper 'snaps out' and 'clips in'
black arrows = holes for the plastic pins
red arrows = holes for 10mm bolts that attach to skid plate
Not shown are the locations for the 4 (per side) Phillips-head screws that hold the bumper to the fender well liner.
