Removal Procedure
- Disable the SIR system. Refer to SIR Disabling and Enabling in SIR.
- Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
- Remove all related panels and components.
- Repair as much of the damage as possible to factory specifications. Refer to Dimensions - Body .
- Note the location and remove the sealers and anti-corrosion materials from the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair in Paint/Coatings.
- Cut the panel where sectioning is to be performed.
- Locate and drill out all factory welds. Note the number and location of the welds for installations of the service part.
- Remove the damaged quarter panel.
Caution: Refer to Approved Equipment for Collision Repair Caution in the Preface section.
Caution: Refer to SIR Caution in the Preface section.
Important: Section in specified areas only. Sectioning outside of these areas may compromise the structural integrity of the vehicle. The quarter panel can be replaced at factory seams, but requires the roof flange spot welds to be removed along the top of the quarter panel. The sectioning procedures have been developed as a more cost-effective alternative to complete replacement.
Important: When replacing panels that involve servicing of stationary windows, refer to Rear Window Replacement in Stationary Windows.
Caution: Refer to Battery Disconnect Caution in the Preface section.
Caution: Refer to Foam Sound Deadeners Caution in the Preface section.
Important: Do not damage any inner panels or reinforcements.
Installation Procedure
- Cut the replacement quarter panel section in corresponding locations to fit the original panel. The sectioning joint should be trimmed to allow 1½ times the metal thickness at the sectioning joint.
- Create a 50-mm (2-in) backing plate from the unused portion of the service part. Trim the backing plate as necessary to fit behind the sectioning joint where no reinforcement exists.
- Drill 8 mm (5/16 in) plug weld holes along the sectioning cut on the remaining original part. Locate these holes 13 mm (½ in) from the edge and spaced 40 mm (1½ in) apart.
- 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.
- Prepare all attachment surfaces as necessary.
- Apply 3M® weld-thru coating P/N 05916 or equivalent to all mating surfaces.
- Fit the backing plate halfway into the sectioning joint. Clamp and plug weld to the vehicle.
- Position the quarter panel.
- Plug weld accordingly.
- Stitch the weld sectioning joint.
- Clean and prepare all welded surfaces.
- Apply the sealers and anti-corrosion materials to the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair in Paint/Coatings.
- Paint and repair the area. Refer to Basecoat/Clearcoat Paint Systems in Paint/Coatings.
- Install all related panels and components.
- Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
- Enable the SIR system. Refer to SIR Disabling and Enabling in SIR.
Important: In any area damaged beyond recognition, or if structural weld-thru adhesive is present, space the plug weld holes 40 mm (1½ in) apart.
Important: To create a solid weld with minimum heat distortion make 25-mm (1-in) stitch welds along the seam with 25-mm (1-in) gaps between the welds. Then go back and complete the stitch weld.
