Differential Side Gear Clearance

WARNING: This page is about a different car, the 2008 Infiniti M45 and 2008 Infiniti M35. However, it is still accessible from the selected car via links, so may be relevant.

Assemble the differential parts if they are disassembled. Refer to "DIFFERENTIAL ASSEMBLY ".

Place differential case straight up so that side gear to be measured comes upward.

Using feeler gauge, measure the clearance between side gear back and differential case at 3 different points, while rotating side gear. Average the 3 readings, and then measure the clearance of the other side as well.
Side gear back clearance specification:

0.2 mm (0.008 in) or less.

(Each gear should rotate smoothly without excessive resistance during differential motion.)

CAUTION: To prevent side gear from tilting, insert feeler gauges with the same thickness from both sides.

If the back clearance is outside the specification, use a thicker/thinner side gear thrust washer to adjust. Refer to "SIDE GEAR THRUST WASHER ".
When the back clearance is large:

Use a thicker thrust washer.

When the back clearance is small:

Use a thinner thrust washer.

CAUTION: Select a side gear thrust washer for right and left individually.
