This document is an exploded parts diagram showing the front bumper assembly and mounting hardware for Ford Bronco, F-100, F-250, and F-350 trucks. The main illustration depicts the front bumper (part 17757) attaching to the frame assembly via a bracket (17752-3) on F-350 models, using bolt 57482-S2 (torque 40-60 ft. lb.), bolt 383465-S2, bolt 383465 (23472 Bright Black finish), and nut and washer 384695 (torque 17-23 ft. lb.). A top-right inset shows the mounting arrangement applicable to all Bronco, F-100, and F-250 models, with bumper 17757 bolting directly to the frame assembly using bolt 383465 (23472 Bright Black) and nut and washer 384695 torqued to 17-23 ft. lb. A bottom-right detail labeled View A shows the F-350 bracket-to-frame attachment using nut and washer 45350-S2 torqued to 40-60 ft. lb. A reader can learn the part numbers for the front bumper, bracket, and fasteners, the correct torque specifications for each fastener, and how the mounting differs between F-350 trucks (bracket-mounted) and Bronco/F-100/F-250 (direct frame mounting).
