Removal Procedure

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

    Important: The front wheelhouse component is constructed as a unit with the shock absorber tower panel. Therefore, replacement of the component affects the front wheel alignment. When assembling it, either use a jig or follow dimensions on the body repair chart for positioning. It must be welded carefully.

  1. Disable the SIR system. Refer to SIR Disabling and Enabling .
  2. Disconnect the negative battery cable.

    3. Important: The upper strut mounting surface is a dimensionally critical area, and 3-dimensional measuring equipment should be used to locate the front wheelhouse assembly. The front wheelhouse can be serviced as a complete assembly for both the left and right wheelhouses. A wheelhouse front panel is also available to service separately on the left or the right sides.

  3. Remove the sealers and anti-corrosion materials from the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair .

    4. Important:  Be sure to inspect the front of the air inlet and dash panel for damage. If the metal surface is damaged, the air inlet panel must be repaired to restore the structural integrity of the vehicle.

  4. Visually inspect the damaged area. Repair as much of the damage as possible. Refer to Dimensions - Body .
