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 pre-load will be set too low. Low bearing pre-load 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.
