STANDARD PROCEDURE - FRONT FRAME RAIL TIP REPLACEMENT

CAUTIONThis procedure is designed to replace the front frame rail tips that have been damaged in the crush initiator zones. Prior to any cutting, the vehicle must be mounted on the appropriate frame repair equipment (frame rack), checked with three dimensional measuring equipment, and the necessary pull corrections made without the use of heat. If damage remains in the frame beyond the area covered by this service part after the pull, the frame must be replaced in its entirety. If damage to the front body structure is evident, repair the Front End Sheet Metal (FESM) fender rails as necessary.

Refer to FRAME, WARNING and FRAME, SPECIFICATIONS .

CAUTIONInspect the tire winch assembly for damage. If any one or more of the following are evident, replace the winch assembly. Indications of cracked or bulging plastic. Housing flanges are bent or cracked. If winch was loose before repair. If the rivet heads are separated from the housing in any way.
