Wheel Bearing Adjustment - F-250/F-350
Adjustment
NOTE:
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.
NOTE:
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.
