F 350 2WD Super Duty V8-5.4L SOHC VIN L (2002)
Wheel Bearing: Adjustments
Front Suspension - 4x2
Wheel Bearing Adjustment - F-250, F-350, F-450, F-550
CAUTION: Wheel seals on the front axles must be replaced any time the axle lubricants are changed from factory-installed mineral lube to synthetic
lube or vice versa. If bearings are adjusted too tightly, they will overheat and wear rapidly. An adjustment that is excessively loose can cause pounding
and contribute to uneven tire wear, steering difficulties and inefficient brakes. Check bearing adjustment at regular inspection intervals. New wheel
seals must be installed when the hub is removed. A damaged or worn seal can permit bearing lubricant to reach the brake linings, resulting in
ineffective brake operation and necessitating premature replacement of linings. To check the wheel bearing adjustment, raise the front of the vehicle.
Grasp the tire at the sides, and alternately push inward and pull outward on the tire. If any looseness is felt, adjust the front wheel bearings as follows.
NOTE: Super Duty F-250, F-350 shown, Super Duty F-450, F-550 similar.
1. Remove the hub cap from the hub.
2. Remove the cotter pin and the castellated nut.
3. While rotating the wheel, tighten the adjusting nut to specification as illustrated to seat the bearings.
