How to Replace a Frontier Bumperby Tony Oldhand
Replacing the bumpers of a Nissan Frontier is not that difficult, but you have to take your time and work carefully. Most Frontiers front bumpers have a bumper cover and an inner support beam; and on most Frontiers, the rear bumper is a one-piece unit. If your Frontier was in an accident, it will be necessary to inspect all components for damage and replace the damaged parts, which are readily available either from Nissan dealerships or aftermarket suppliers.
Removing and Replacing Your Frontier's Front Bumper
Park your Frontier on a hard, level ground, such as a driveway. Place the vehicle in "Park" and set the emergency brake firmly. Place the wheel chocks on the front wheels.
Lay on the mechanic's creeper, and wheel yourself under the front bumper area. Locate and familiarize yourself with all the points where the front bumper beam and bumper cover attach to to the vehicle. Locate all the electrical connectors for your fog and ancillary lights. On a second generation Frontier model LE, some owners report that you may have to pull the inner fender liners to be able to reach the attachment bolts.
Disconnect the positive (+) and negative (-) connectors from your battery.
Disconnect all the electrical plugs that feed the fog and ancillary lights.
Instruct two helpers to stand on either side of the cover, and have them support the weight of the cover. Remove the cover bolts carefully, as your helpers takes up the weight.
Instruct your helpers to walk the cover away from the vehicle, and set it off to the side.
Inspect the inner bumper beam carefully. If damaged, you will have to replace it.
Instruct your helpers to stand on either side of the bumper beam. As they take up the weight, remove the attachment bolts. Instruct your helpers to walk the beam away from the vehicle, and lay it off to the side.
