Remove bumper on '03 Silverado 1500

Someone whacked my fron bumper on Walley's parking lot, now both ends are at an odd angle down. Looks lime they must have hi it high and pushed it in at the top. As far as I can tell it doesn't look bent.

Now my question. How, and how easy is it to pull the bumper off and re-align?

The reason I ask is I don't want to go poking around under the bumper without knowing what to watch out for. I would hate to set off the air bags etc.

Thanks.

To remove the bumper is easy you will have to remove at least 10 bolts that will be real tight... I would recommend you lift the truck on some ramps for easier access to the bumper...first you may have to remove the top plastic on the bumper and from the bottom you can unscrew the bolts holding the bumper to the frame... And after you get all the bolts it should come off....
