2	Front Differential Carrier Assembly CAUTION: If the bearings are not properly seated into the bearing cups, the washer selection will be inaccurate and the bearing preload will be set too low. Low bearing preload will cause premature failure of the front differential drive pinion gear. Procedure Rotate the differential assembly 10 revolutions to allow the bearings to seat into the cups.
