Removal Procedure

Caution: Refer to Approved Equipment for Collision Repair Caution in the Preface section.

Caution: When working with any type of glass or sheet metal with exposed or rough edges, wear approved safety glasses and gloves in order to reduce the chance of personal injury.

Caution: Sectioning should be performed only in the recommended areas. Failure to do so may compromise the structural integrity of the vehicle and cause personal injury if the vehicle is in a collision.

Important: When replacing panels that involve servicing of stationary glass, refer to service bulletin 43-10-45 before performing any priming or refinishing.

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 in SIR.
  2. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.

  14. Remove the damaged hinge pillar.

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 1 ½ 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. 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.

  4. Object Number: 768610  Size: SH

    Important: In any area damaged beyond recognition, space the plug weld holes every 40 mm (1 1/2 in) apart.

  5. 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.
  6. Prepare all mating surfaces as necessary.
  7. Apply 3M Weld-Thru Coating P/N 05913 or equivalent to all mating surfaces.

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

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

  13. Object Number: 787665  Size: SH
  14. 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.
  15. Clean and prepare all of the welded surfaces.
  16. Apply sound deadening materials as necessary.
  17. Apply the sealers and anti-corrosion materials to the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair in Paint and Coatings.
  18. Paint the repaired area. Refer to Basecoat/Clearcoat Paint Systems in Paint and Coatings.
  19. Install all of the related panels and components.
  20. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
  21. Enable the SIR system. Refer to SIR Disabling and Enabling in SIR.
