Ford Bronco F-150 F-250 F-350 Front Hub Locknut Wrench Diagram (E9807-A)
Service illustration showing a hex locknut wrench used on the front hub of F-150/Bronco and F-250/F-350 with automatic locking hubs.
This document is a single illustrated page from a Ford service procedure showing the removal or installation of the front wheel bearing locknut on a 4x4 front hub. The line drawing depicts a technician's hands using a large hex locknut wrench on the spindle nut behind the brake rotor, with the wheel studs and hub assembly visible. The callout text specifies the correct special tool by application: a 2-1/2 inch hex locknut wrench is used for the F-150 and Bronco with automatic locking hubs, while a 2-3/4 inch hex locknut wrench is used for the F-250 and F-350 with automatic locking hubs. The figure is identified by the reference code E9807-A. The page contains no torque specifications, part numbers, or step-by-step instructions—its purpose is to identify the required locknut wrench size for each truck model and to show how the tool engages the locknut on the spindle. It is one page of a multi-page front wheel bearing service set (companion scans bearing2 through bearing5 in the same album).
