Repair Procedure

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

Important

This procedure is used when front frame rail end is kinked or damaged beyond repair forward of the front crossmember. The service part must be cut from an underbody side rail assembly.

  1. Remove all related panels and components, support powertrain and remove front crossmember bolts as necessary.
  2. Notice: When determining the area to perform the sectioning near a riv-nut 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.

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