Measure the backlash between differential bevel gear and differential pinion. If backlash is not within specified value, install a suitable washer to adjust. < Ref. to BEVEL PINION GEAR BACKLASH , INSPECTION, Front Differential Assembly . >
NOTE: Be sure the pinion gear teeth contacts adjacent gear teeth during measurement.
