Correction code: 10101907102 10101907202 NOTE: Unless explicitly stated in the procedure, the above correction code includes all Collision Repair work required to perform this procedure, including the linked Collision Repair procedures. Do not stack Collision Repair correction codes unless explicitly told to do so. Add any associated mechanical procedures needed to perform this procedure.

Repair Information

  • Review all collision repair general practices and safety documentation and wear the appropriate PPE (Personal Protective Equipment) before beginning this procedure.
  • This procedure can be completed without using a frame bench.
  • This component may be replaced in a single repair as a single complete component, using the ASY, RR WHEELHOUSE OTR (Rear Wheel Arch) service part and the instructions in the Repair Procedure section of this document. Alternatively, any individual section or any combination of sections of the Rear Wheel Arch can be replaced so long as the guidelines from the Sectioning Guidelines are followed.

Sectioning Guidelines

General sectioning guidelines:
  • It is allowable to cut through a clearance hole or a non functional hole (exterior trim hole), as described below.
  • Do not cut within 25 mm. of the center of a bolt hole or stud.
  • Sections do not require fasteners at butt or overlap joints unless specifically indicated.
  • Gaps between panels of overlaid and butt joints should be as small as possible to maximize joint strength.
  • Seal all open seams after structural adhesive has cured.

The image below shows the Rear Wheel Arch (complete). The colored areas indicate if sectioning is allowed. Compare the damaged area of the vehicle's Wheelhouse Outer to the image below, then use the repair criteria corresponding to the color of the highlighted area to find the criteria to use to determine if the damaged area of the component can be sectioned.
