Frame and Body Mounting: Notes
The frame consists of 2 steel-channel rails, 10 crossmembers for Explorer Sport Trac or 8 crossmembers for Explorer/Mountaineer including a front crossmember, transmission support crossmember and a rear crossmember (trailer hitch). New side rails and welded crossmembers, including the trailer hitch, are not installed separately. A front frame rail repair kit is available if the front rail is to be repaired and a rear crossmember (hitch) repair kit is available if the rear crossmember or rail is to be repaired.
The 1B crossmember and transmission crossmember are included in assembly to the frame but can be serviced separately. For any frame repair, refer to BODY REPAIRS article.
