Disassembly and Assembly: Assembly

WARNING: This page is about a different car, the 2019 Infiniti Q50. However, it is still accessible from the selected car via links, so may be relevant.

Install side gear thrust washers with the same thickness as the ones installed prior to disassembly or reinstall the old ones on the side gears.

Install side gears and thrust washers into differential case.
CAUTION:
- Never reuse circular clip.
- Make sure that the circular clip is installed to side gear (side retainer side).
Align 2 pinion mate gears in diagonally opposite positions, then rotate and install them into differential case after installing thrust washer to pinion mate gear.

Measure side gear end play. If necessary, select the appropriate side gear thrust washers.

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

: Refer to Differential Side Gear Clearance .

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. For selecting thrust washer, refer to the latest parts information.

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.

Drive a lock pin into pinion mate shaft, using a punch.
