Move side gears up and down, and measure the clearance as shown.
Clearance between side gear and differential case: 0.1 - 0.2 mm (0.004 - 0.008 in)

CAUTION: There must be no resistance and the gears must rotate freely.

If the clearance measured is not within specification, adjust the clearance by changing the thrust washer thickness.
Turn the differential case upside down, and measure the clearance between the side gear and differential case on the other side to the same specifications, adjust using a thrust washer as necessary.
