10. Install a set of Underbody Rails (XR3Z-76101W09-AA - Left and XR3Z-76101W08-AA - Right). Refer to Figure 1 to determine where to place
the rails to the underbody. The underbody rails will need to be welded to the underbody of the vehicle by referring to the following:
^
A Mig welder and standard body Gas Metal Arc Welding repair procedure should be used. Remove the paint in the welding area only for
better weld penetration.
^
The welds should have a minimum 5mm weld bead and a minimum total length of 75 mm on both sides of the rail and at both front and rear
ends (Figure 2).
^
Upon completion, the welded area should be treated for corrosion using Super Sealant (F3AZ-19515-SA or equivalent).
^
If this vehicle has an automatic transmission, transfer the attaching shift cable retainer from the body to the bracket that is located on the
underbody rails.
