Removal Procedure

    Object Number: 314563 Size: SH

    Important: The quarter panel is serviced as a one piece service assembly which includes the lock pillar and the lower rear quarter close-out panel. Replacement of the quarter panel requires removal of the back glass. Due to the manner in which the quarter panel attached to the door frame, a special sectioning procedure has been developed for improved serviceability.

  1. Remove all related panels and components including the back glass.
  2. Visually inspect and restore as much of the damage as possible to factory specifications.
  3. Remove sealers and anti-corrosion materials as necessary.

    4. Object Number: 314564 Size: SH
  4. Note the size of the service part and locate the sectioning joints at the sail panel (1) and rocker panel accordingly.
  5. Measure 50 mm (2 in) down from the factory silicon bronze joint (1) to locate sectioning cut.
  6. Locate, mark, and drill out all factory welds. Note the number and location of welds for installation of the service assembly.
  7. Perform additional sectioning procedures as necessary.
  8. Remove the damaged quarter panel.

Installation Procedure
  1. Prepare the mating surfaces as necessary.
  2. Temporarily position the service panel on the vehicle.

    3. Object Number: 314565 Size: SH
  3. Trim the original panel to leave a gap of one and one-half times the thickness of the metal at the sectioning joint.
  4. Cut 100 mm (4 in) piece from the original quarter panel for backing plates (2) .
  5. Remove the flange on each side of the backing plates so that they will fit behind the sectioning joints.
  6. Drill 8 mm (5/16 in) plug weld holes as necessary in the locations noted from the original panel.
  7. Drill plug weld holes along the sectioning cuts of the service part. These should be located approximatly 25 mm (1 in) from the edge of the cuts.
  8. Prepare the mating surfaces and position the backing plates with 50 mm (2 in) of the backing plates.
  9. Check for proper fit and alignment.
  10. Plug weld accordingly.
  11. Stitch weld along the entire joints.
  12. Make 25 mm (1 in) gaps between them.
  13. Go back and complete the stitch welds. This will create solid joints with minimal heat distortion.
  14. Complete all other welds and sectioning procedures as necessary.
  15. Clean and prepare all welded surfaces.
  16. Prime with 2-part catalyzed primer.
  17. Apply sealers and anti-corrosion materials as necessary.
