WARNING:
- Frame rail crush zones absorb crash energy during a collision and must be replaced if damaged. Straighten damaged frame rails to correct frame dimensions prior to frame member sectioning. Failure to follow these instructions may adversely affect frame rail performance and may result in serious personal injury to vehicle occupant(s).
- Invisible ultraviolet and infrared rays emitted in welding can injure unprotected eyes and skin. Always use protection such as a welder's helmet with dark-colored filter lenses of the correct density. Electric welding will produce intense radiation, therefore, filter plate lenses of the deepest shade providing adequate visibility are recommended. It is strongly recommended that persons working in the weld area wear flash safety goggles. Also wear protective clothing. Failure to follow these instructions may result in serious personal injury.
- Never install used or reconditioned parts (as specified below) from pre-owned, salvaged or damaged vehicles. The use of such parts could lead to serious injury.
Never use non-Ford parts or accessories for completing repairs.
Ford Motor Company does not approve or recognize body and structural repair procedures, tools, parts or anything but new genuine Ford equipment. Ford cannot attest to the safety, quality, durability or legality of non-Ford parts or accessories. Use of such parts could lead to serious personal injury as they may contain damage which is not visible.
Ford does not approve use of the following:
- Salvaged or used parts
- Major body clips or assemblies from salvage vehicles
- Aftermarket structural or body components
- Salvaged or reconditioned wheels
- Used supplemental restraint system (SRS) components
- air bags
- restraint system modules
- safety belts, buckles or retractors
- crash sensors
Returning a vehicle to pre-accident condition can only be assured if repair procedures are carried out by skilled technicians using new genuine Ford parts and Ford-approved methods. Structural component repair procedures approved by Ford, using genuine Ford parts, have been validated by Ford Motor Company engineers.
Ford Motor Company does not endorse, cannot attest to, and makes no representations regarding structural repairs (frames, rails, aprons and body panels) carried out using non-genuine Ford Motor Company parts or non-Ford-approved methods. In particular, Ford makes no representations that the vehicle will meet any crash safety or anti-corrosion performance requirement. Such parts and methods have not been tested by Ford, and may not meet Ford's requirements for safety, performance, strength, quality, durability and corrosion protection. Ford Motor Company bears no responsibility or liability of any kind if repairs are performed using alternative structural component repair procedures and/or parts.

NOTICE: A frame rail sectioning kit is not available for this vehicle. Frame rail replacement must be done at the factory seams. Failure to follow this direction will result in an incorrect repair and vehicle energy management will be compromised.
1. Position the vehicle on a frame repair rack following the manufacturer's recommendations. Measure the vehicle to determine if the body requires rough straightening and alignment. For dimensional information, refer to Body.
2. Remove the hood.
3. Remove the fender(s) from the affected side(s).
4. Remove the front bumper cover and reinforcement.
5. Remove the battery.
6. Remove the front strut from the affected side of the vehicle.
7. Remove the engine mount from the affected side of the vehicle.
8. Remove the subframe.
9. Disconnect and position aside the Anti-Lock Brake System (ABS) sensor wire.
10. NOTE: Use care not to drill through to fender apron or A-pillar when removing the frame rail.
Carefully drill out the spot welds and remove the outer frame rail.
11. NOTE: Use care not to drill through to fender apron or A-pillar when removing the frame rail.
Carefully drill out the spot welds and remove the inner frame rail.
12. Dress any plug weld nuggets on the vehicle underbody structure resulting from inner or outer rail removal.
Installation
1. NOTE: Factory spot welds may be substituted with either resistance spot welds or MIG plug welds. Spot/plug welds should equal factory welds in both location and quantity. Do not place a new spot weld directly over an original weld location. Plug weld hole should equal 8 mm (0.31 in) diameter.
Apply a locally available weld-through primer only to the immediate weld locations of the inner and outer frame rails.
2. Install and clamp the service replacement inner frame rail in place. Tack weld and verify correct alignment of the frame rail.
3. NOTE: Factory spot welds may be substituted with either resistance spot welds or MIG plug welds. Spot/plug welds should equal factory welds in both location and quantity. Do not place a new spot weld directly over an original weld location. Plug weld hole should equal 8 mm (0.31 in) diameter. Install and clamp the service replacement outer frame rail in place.
- Verify correct alignment of the outer frame rail.
4. Using a MIG welder or resistance spot welder, plug weld along the top and bottom seam of the service replacement rails.
5. Use a dye penetrant or equivalent to determine if any cracks or large voids exist, grind out any defects that exist and repair until the weld is free of defects.
- Dress welds as necessary.
6. Apply corrosion protection. For additional information, refer to Restoring Corrosion Protection Following Repair.
7. MIG plug weld or resistance spot weld a new front bumper reinforcement mounting plate to the front frame rail assembly.
8. Install the subframe.
9. Install the engine mount from the affected side of the vehicle.
10. Install the front strut.
11. Connect the Anti-Lock Brake System (ABS) sensor wire.
12. Install the battery.
13. Install the fender(s).
14. Install the front bumper cover and reinforcement.
15. Install the hood.
