F 350 2WD Pickup V8-7.3L DSL (1988)
Wheel Bearing: Adjustments
1. Raise the vehicle until the tire clears the floor and install safety stands.
2. Remove the wheel cover.
3. Remove the grease cap from the hub. Wipe the excess grease from the end of the spindle. Remove the cotter pin and locknut.
4. Loosen the adjusting nut three turns. Attempt to obtain running clearance between the rotor brake surface and the disc pads by rocking the wheel,
hub and rotor assembly in and out several times to push the pads away from the rotor. If running clearance cannot be maintained throughout
bearing adjustment in Steps 5 and 6, the caliper must be removed.
NOTE: Do not pry on the phenolic caliper piston.
5. Tighten the wheel adjusting nut to 30-33 Nm (22-25 ft lbs) while rotating the disc brake rotor in the opposite direction.
6. Back off the adjusting nut 1/8 turn and install the retainer and new cotter pin without additional movement of the adjusting nut. Bearing end play
should be 0.025-0.254mm (0.001-0.010 in). Bend the ends of the cotter pin around the castellated flange of the locknut.
7. Check front wheel rotation. If the wheel rotates properly, reinstall the grease cap and wheel cover. If rotation is noisy or rough, remove and inspect
the bearings. Service as required.
WARNING: Before driving the vehicle, pump the brake pedal several times to restore normal brake pedal travel.
