Lincoln Navigator: Rear End Sheet Metal Repairs / Rear Floor Panel Crossmember. Removal and Installation

Special Tool(s) / General Equipment

Materials

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 self-piercing rivet (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 repairs areas that utilize structural adhesive 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: Left-hand (LH) side shown, right-hand (RH) side similar.

NOTE: Flow-Drill Screw (FDS) fasteners are not reused. Remove and discard.

NOTE: Standard wheelbase shown, long wheelbase similar.
