    1. Clearance between side gear and differential case: 
    2. 0.1 - 0.2 mm (0.004 - 0.008 in) 
  4. If not within specification, adjust the clearance by changing thrust washer thickness.
  5. Turn differential case upside down, and measure the clearance between side gear and differential case on the other side in the same way.
