This document is a Ford exploded-parts illustration sheet showing four rear bumper assembly configurations for Ford trucks and Broncos: (1) Rear Bumper Flareside, (2) Rear Contour Bumper Bronco Shown – Style Side Typical, (3) Step Bumper Style Side All, and (4) Step Bumper Bronco – All. Each diagram identifies bumpers, inner and outer rear bumper brackets/arms, license plate brackets, stone deflector, foam tape, rear bumper pad, and all attaching hardware (bolts, nuts, U-nuts, screws) with Ford basic and hardware part numbers such as bumper 17775 and 17906, brackets 17787 and 17795 variants, license bracket 13418 and 13406-A, and fasteners N620484-S2, N621945-S2, N605827-S2, N800883-S100, N800974-S100, and N800976-S100. Torque specifications are given throughout: main bumper bracket fasteners torque to 81-122 N·m (60-90 ft-lb), while smaller attaching nuts torque to 23-31 N·m (17-23 ft-lb). A reader can use this sheet to identify part numbers for ordering replacement rear bumper components, understand how the brackets and bumpers assemble to the frame and body, and apply correct fastener torque values when installing flareside, contour, or step rear bumpers on style-side trucks and Broncos.
