Bumper Reinforcement - Front

This procedure removes and replaces the front bumper reinforcement bar on a 2005 Dodge Viper, requiring removal of the front fascia and disconnection of impact sensors.

Warnings

Tools required

Parts

• Front bumper reinforcement bar × 1 — Use OEM specification
• Impact sensor (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Disconnect battery negative terminal and wait 2 minutes for airbag system capacitor discharge
4. Allow engine to cool completely if vehicle was recently operated
5. Raise front of vehicle using floor jack and support securely on jack stands at manufacturer-specified lift points

Procedure

1. 1

   Remove front fascia lower fasteners
   Working from underneath, locate and remove the fasteners securing the lower edge of the front fascia per the vehicle-specific service manual. Remove the retaining fasteners along the bottom edge of the fascia and in the wheel well areas. Check for fasteners behind the front wheels where the fascia meets the fender liner. Note: the Viper fascia is composite and uses specific bolt/nut fasteners — confirm exact locations before removal.
2. 2

   Remove front fascia upper fasteners
   Open the hood. Locate and remove the fasteners securing the top edge of the front fascia to the radiator support. These will be along the top edge where the fascia meets the body. Remove any screws or clips in this area.
3. 3

   Disconnect fog light connectors
   If equipped with fog lights, locate the electrical connectors behind the fascia. Press the release tabs and disconnect the fog light wiring harnesses. Note the routing of the wiring for reinstallation.
4. 4

   Remove front fascia
   With all fasteners removed and electrical connections disconnected, carefully pull the front fascia away from the vehicle. Start at one side and work around, releasing any remaining clips. Have an assistant support the fascia to prevent damage. Set the fascia aside in a safe location where it will not be damaged.
5. 5

   Disconnect impact sensors
   Check for any impact/crash sensors that may be mounted on or near the front bumper reinforcement bar. If present, press the release tabs and disconnect the electrical connectors from each sensor, noting sensor locations and orientation for reinstallation. Note: this platform may not use bumper-mounted impact sensors — verify against the vehicle-specific service manual before proceeding.
6. 6

   Remove impact sensors from reinforcement
   Remove the mounting bolts securing each impact sensor to the bumper reinforcement bar. Remove the sensors and set them aside if they are being reused.
7. 7

   Mark reinforcement position
   Before removing the reinforcement bar, use a marking pen or tape to mark its position relative to the frame rails. Mark the location of the mounting brackets and the vertical and horizontal alignment. This will ensure proper positioning during installation.
8. 8

   Remove reinforcement mounting bolts
   Locate the mounting bolts securing the bumper reinforcement to the frame rails on each side. These are typically large bolts connecting the reinforcement end brackets to the frame. Support the reinforcement bar with one hand or have an assistant hold it, then remove the mounting bolts on both sides.
9. 9

   Remove bumper reinforcement
   With all mounting bolts removed, carefully lower the bumper reinforcement bar away from the frame rails. The reinforcement is heavy, so use proper lifting technique and have an assistant help. Inspect the mounting points on the frame for damage or corrosion.
10. 10

    Install new bumper reinforcement
    Position the new bumper reinforcement bar to the frame rails, aligning it with the marks made during removal. Have an assistant support the reinforcement while you align the mounting holes. Install the mounting bolts on both sides and hand-tighten initially to allow for alignment adjustment.
11. 11

    Align and torque reinforcement bolts
    Verify the reinforcement is properly aligned with your reference marks and centered on the vehicle. Ensure equal spacing on both sides. Torque the mounting bolts to specification in an alternating pattern (left side, then right side) to ensure even seating.
12. 12

    Install impact sensors
    Install the impact sensors onto the new bumper reinforcement bar in their original positions and orientations. Install and torque the sensor mounting bolts to specification. Reconnect the electrical connectors to each sensor, ensuring they click fully into place.
13. 13

    Reinstall front fascia
    With an assistant, position the front fascia back onto the vehicle. Align the fascia with the body panels and ensure all mounting points line up correctly. Reconnect the fog light electrical connectors if equipped.
14. 14

    Secure front fascia
    Install and tighten all fascia fasteners, starting with the upper fasteners at the radiator support, then the lower fasteners and wheel well fasteners. Ensure all push clips are fully seated and all screws are snug. Verify the fascia is evenly aligned with uniform gaps on both sides.
15. 15

    Final checks and battery reconnection
    Lower the vehicle from jack stands. Inspect the fascia alignment and verify all fasteners are tight. Reconnect the battery negative terminal. Start the vehicle and verify the airbag warning light follows its normal self-check sequence (illuminates briefly then extinguishes). If the airbag light remains on, have the system scanned for fault codes.

Reassembly

1. Torque all mounting bolts to specification using the values provided
2. Ensure all electrical connectors are fully seated and locked
3. Verify fascia alignment and panel gaps before final tightening
4. After reconnecting the battery, verify airbag system warning light operates normally

Verification

• Confirm all fascia fasteners are tight and fascia is securely mounted
• Verify bumper reinforcement is solidly mounted with no movement
• Check that airbag warning light extinguishes after starting vehicle
• Inspect fascia alignment and panel gaps for symmetry
• Verify fog lights function properly if equipped
