F 350 2WD Super Duty V10-6.8L (2009)
Wheel Bearing: Adjustments
Wheel Bearing Adjustment
NOTICE: 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.
NOTICE: 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 the linings.
NOTE: Super Duty F-250, F-350 shown, Super Duty F-450, F-550 similar.
