Removal

NOTICE: Panel sectioning is prohibited within 50 mm of door hinge, door striker, restraints and suspension anchoring points.

NOTE: Self-piercing rivet (SPR) fasteners may not be placed directly over original SPR location. They must be placed adjacent to original location matching original quantity.

NOTE: Aluminum body panels are highly receptive to heat transfer. With the extensive use of structural adhesives and non-structural sealers used in vehicle construction, the potential of heat transfer could impact adhesives and sealers in non-associated panels during the repair process. Many repair areas that utilize structural adhesives may be separated after fastener removal by using a panel chisel along the joint/flange. Using heat not exceeding 425° F to loosen a bonded panel should only be done when all panels in the joint will be replaced and new adhesive applied.

NOTE: The floor panel reinforcement may be sectioned providing the sectioning guidelines are adhered to. The following procedure assumes full component replacement. Adjust to meet repair needs.

NOTE: LH side shown, RH side similar.

NOTE: Long wheelbase shown, short wheelbase similar.
