The full body-side outer panel comes as a complete assembly and can be replaced at factory seams after the removal of the fixed glass and roof. Any one of these service procedures can be performed separately or in any combination, depending upon the extent of damage to the vehicle. Sectioning must take place in specified areas only.

  1. Disable the SIR system. Refer to SIR Disabling and Enabling .
  2. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
  3. Remove all related panels and components.
  4. Repair as much of the damage as possible .
  5. Caution: Foam sound deadeners must be removed from areas within 152.4 mm (6 in) of where flame is to be used for body repairs. When reinstalling foam sound deadeners, avoid inhaling fumes as bodily injury may result.

  6. Remove sound deadeners as necessary and note their location.

Installation Procedure


    Object Number: 768607  Size: SH
  1. Cut the outer front hinge pillar in corresponding locations to fit the remaining original panel. The sectioning joint should be trimmed to allow a gap of 1½ times the metal thickness at the sectioning joint.

  2. Object Number: 768608  Size: SH
  3. Create a 50 mm (2 in) backing plate from the unused portion of the service part for the windshield area.
  4. Create a 100 mm (4 in) backing plate from the unused portion of the service part for the rocker area. Trim the backing plates, as necessary, to fit behind the sectioning joint.

  5. Object Number: 768610  Size: SH

    Important: If the location of the original plug weld holes can not be determined, place plug weld holes 40 mm (1½ in) apart.

  6. Drill 8 mm (5/16 in) plug weld holes in the service part, as necessary, in the locations noted from the original panel and along the sectioning cut.
  7. Prepare all mating surfaces, as necessary.
  8. Apply 3M Weld-Thru Coating P/N 05913 or equivalent to all mating surfaces.

  9. Object Number: 768611  Size: SH
  10. Fit the backing plates halfway into the sectioning joints, clamp in place and plug weld to the vehicle.
  11. Align outer front pillar using 3-dimensional measuring equipment.

  12. Object Number: 787663  Size: SH
  13. Plug weld accordingly.

  14. Object Number: 787665  Size: SH
  15. To create a solid weld with minimum heat distortion, make a 25 mm (1 in) stitch weld along the seam with 25 mm (1 in) gaps between them. Go back and complete the stitch weld.
  16. Clean and prepare all of the welded surfaces.
  17. Apply the sealers and anti-corrosion materials to the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair .
  18. Paint the repaired area. Refer to Basecoat/Clearcoat Paint Systems .
  19. Install all of the related panels and components.
  20. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
