take out the tail lights. this will reveal a screw and a button fastener...
then under the bumper there are 2 button fasteners, undo those
then if you look at the rear drivers wheel, there is a screw at about 2:00 oclock right inside the wheel well, undo that, and there maaaay be one at the bottom of the bumper... same on passanger side...
then its just clips that hold it on so work them off...
