NOTE:
This section explains the procedures after removal of all related parts. For the related parts' removal procedure, refer to the appropriate Service Manual.
The component replacement procedure described here is only for new Honda-supplied parts, as needed, according to the area and the degree of damage on the body.
Check the rear frame position for damage. If necessary, replace the rear floor frame complete. The rear portion of the rear frame cannot be sectioned.
