1. Install the spacer on each side gear, then install the side gears into the center differential case.

NOTE: When installing new side gears, use spacers of a medium thickness (0.66 - 0.73 mm) (0.0260 - 0.0287 inch).





2. Install a washer on the backside of each pinion.
Simultaneously engage all four pinions with the side gears, and install them into position while rotating, then install the pinion shaft holder.





3. Insert the pinion shafts into the pinions.
4. Install the lock pins as indicated in the illustration.





5. Insert the front output shaft into each side gear, then install the snap ring.
6. Install the spacer on each side gear. Next, install the side gears into the center differential case.

NOTE: When installing new side gears, use spacers of a medium thickness (0.66 - 0.73 mm) (0.0260 - 0.028 7 inch).





7. Install the center differential flange on the differential case while aligning the match marks. Secure it temporarily in place using machine screws in four places.





8. Measure the backlash between the side gears and pinions.
Standard value: 0.025 - 0.150 mm (0.0010 - 0.0059 inch)
9. If the backlash does not fall within the standard value range, select other appropriate spacers, replace the existing spacers with them, and measure the backlash once again.

NOTE: Adjust the backlash on each side so that it is equal to the backlash on the other side.
