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

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.

Important: . The front wheelhouse service panel is serviced as a complete assembly, which includes the upper front strut mounting surface. The upper strut mounting surface is a dimensionally critical area. Use dimensional measuring equipment to locate the front wheelhouse assembly.




3. Remove the sealers and anti-corrosion materials from the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair in Paint and Coatings.
4. Remove the upper tie bar. Refer to Upper Tie Bar Replacement .
5. Remove the upper rail. Refer to Upper Rail Replacement .

Important: Inspect the front of the cowl for damage. If the metal surface is damaged, the cowl panel must be repaired to restore the structural integrity of the vehicle.

6. Repair as much of the damage as possible.



7. Locate, mark, and drill out all factory welds attaching the front wheelhouse panel to the lower frame rail. Note the number and location of welds for installation of the service assembly.



8. Locate, mark, and drill out all factory welds attaching the wheelhouse panel to the cowl panel.



9. Locate, mark and drill out all factory welds attaching the wheelhouse panel to the front lower and upper rail.



10. Locate, mark and drill out all factory welds attaching the wheelhouse panel to the upper cowl panel.



11. Remove the wheelhouse from the vehicle.

1. Prepare the mating surfaces as necessary.
2. Apply 3M Weld-Thru Coating P/N 05913 or equivalent to all mating surfaces.
3. Drill 8-mm (5/16-in) plug weld holes, as necessary, in the locations noted from the original assembly.

Important: If the location of the original plug weld holes can not be determined, or if structural weld-thru adhesive is present, space the plug weld holes every 40 mm (1½ in).

4. Position the wheelhouse on the vehicle. Check for proper fit using 3-dimensional measuring equipment.
5. When the service assembly is correctly positioned, plug weld accordingly.
6. Install the upper rail. Refer to Upper Rail Replacement .
7. Install the upper tie bar. Refer to Upper Tie Bar Replacement .
8. Measure frequently to ensure proper fit and alignment.
9. Clean and prepare all welded surfaces.
10. Apply the sealers and anti-corrosion materials to the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair in Paint and Coatings.
11. Paint the repaired area. Refer to Basecoat/Clearcoat Paint Systems in Paint and Coatings.
12. Install all related panels and components.
13. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
14. Enable the SIR system. Refer to SIR Disabling and Enabling in SIR.
