The bumper assembly is heavy and somewhat awkward to remove and install, so it is important to support the bumper when the bolts are removed and have an assistant help during this procedure. To remove the front bumper, first apply the parking brake, raise the vehicle, and support it securely on jackstands. Remove the under cover splash shield and open the hood. Disconnect the cable from the negative battery terminal and any wiring that would interfere with bumper removal. For models from 1990 to 2000, remove the screws from the front turn signal/running lights and disconnect fog lights if equipped. For models from 1990 to 1998, remove the radiator grille and headlights, then the screws from the lower grille moldings. Remove the screw(s) attaching the bumper fascia to the fender at the wheel cutout area, and for models from 1990 to 1994, also remove screws at the grille area. For models from 1990 to 1994, remove the attaching screws at both angle brackets and then the front bumper reinforcement by removing the retention bolts. For models from 1995 and later, remove the attaching screws along the bottom of the bumper cover and the front bumper reinforcement nuts from the body attachment points in the grille area. Carefully remove the bumper while disconnecting the front turn signal light connectors, and lower it to the floor or padded wooden blocks. Remove the bumper cover bolts attaching the cover to the bumper reinforcement, push out the upper bumper cover tabs, and then remove the bumper cover and energy-absorbing foam. Installation is the reverse of removal. For the rear bumper, apply the parking brake, raise the vehicle, and support it securely on jackstands. Disconnect the cable from the negative battery terminal and any wiring that would interfere with bumper removal. Remove the rear stop/turn signal light, and for models from 1990 to 1994, remove the trunk end trim, while for models from 1995 and later, remove the trunk side trim panels. For models from 1990 to 1994, remove the two bumper bracket covers at the trunk end and the bumper reinforcement attachment nuts. Remove the rear side marker lights and, for hatchback models from 1990 to 1994, the rear license plate light. For models from 1990 to 1994, remove the rear bumper retainer bar, and for models from 1995 and later, remove the rear wheel cutout extensions, bolts under the bumper cover, and nuts inside the trunk. For models from 1990 to 1994, remove the screws attaching the bumper cover to the fender at the wheel cutout area, then working under the bumper, remove the rear bumper reinforcement by removing the retention bolts. Carefully lower the bumper part way, supporting it while removing the license plate wiring harness and holder, then lower it fully onto padded wooden blocks. Remove the bumper cover bolts attaching the cover to the bumper reinforcement, then remove the bumper cover and energy-absorbing foam. For models from 1995 and later, remove the bumper cover bolts and the cover from the bumper reinforcement and energy-absorbing foam, along with any side marker lights and other attached parts as required. For models from 1990 to 1994, remove both rear mud flaps as necessary. Installation is the reverse of the removal procedure.
