Ford Bronco/F-150 4x4 Front Hub & Wheel Bearing Exploded Diagram w/ Torque Specs
Exploded parts diagram of the front wheel hub, spindle, and bearings with a numbered item legend and torque specifications.
This document is an exploded parts diagram of a front axle/wheel hub assembly, showing the halfshaft, spindle, wheel bearings, disc brake hub and rotor, lock nuts, thrust washers, and manual locking hub components. Numbered callouts 1 through 22 in the illustration correspond to a legend table listing each part: halfshaft, rolling diaphragm seal (axle), integral spacer needle bearing seal, caged needle bearing, front wheel spindle, spindle rolling diaphragm seal, wheel hub grease seal, inner and outer wheel bearings with bearing cups, front disc brake hub and rotor, pin, inner lock nut, lockwasher, outer lock nut, steel/plastic/splined thrust washers, C-ring, hub body, lock ring, cup, and capscrew. Lettered callouts provide torque specifications: (A) while rotating the front disc brake hub and rotor, tighten the inner lock nut to 68 N·m (50 lb-ft) to seat the wheel bearing, then back the nut off 90 degrees (1/4 turn); (B) tighten the outer lock nut to 217-278 N·m (160-205 lb-ft); (C) tighten the capscrews to 4-6 N·m (35-53 lb-in). The figure carries the reference code E9800-A. A reader can learn assembly order, part names, and the bearing preload/torque procedure for servicing the front hub and wheel bearings.
