As with most installations, the first step is always to review and consult the instructions that come with your products. Our first step was to remove the stock bumper and grille from the vehicle. This step actually took us longer than installing the bumper. Nissan must have enjoyed hiding snap bolts and screws along the inner lip of the bumper and liner, making it a very time-consuming removal process. After the bumper was removed, we went ahead and removed the grille as well.
