2. After assembling, using a thickness gauge measure clearance between snap ring and center differential case.

Clearance:
0 - 0.15 mm (0 - 0.OO59 inch)





3. If the measurement is not within the specification, select suitable snap ring.





4. After assembling, set up a ST1 and ST2 to end of viscous coupling shaft. Move viscous coupling up and down, and measure backlash in the axial direction.
