Removal Procedure

    Important: When the rear rail end is kinked or damaged beyond repair rearward of the rear crossmember, the service part must be cut from an underbody side rail assembly.

    Important: Use the sleeved butt joint method to install rear frame ends.

    Important: When determining the area to perform the sectioning near a riv-nut hole (within the recommended areas), choose a location that centers the sleeve through the hole. This will ensure that riv-nut fasteners remain straight during installation.

  1. Determine sectioning joint location within the recommended area.
  2. Perform sleeved butt-joint sectioning as required.
  3. Apply anti-corrosion materials to all inner surfaces as necessary.
  4. • Do not combine paint systems.
    • Refer to paint manufacturer's recommendations.
  5. After sectioning repairs are completed, attach panels and components as necessary.
