>>A<< SPACER, SIDE GEAR, WASHER, PINION AND PIN-
ION SHAFT INSTALLATION
1. Mount a spacer on the back surface of the side gear, and 

then install the side gear in the differential case.
NOTE: When a new side gear is to be installed, use a 
medium thickness spacer [0.93 to 1.00 mm (0.0366 to 
0.0395 inch)].

2. Set the washer on the back of each pinion, and put both 

pinions simultaneously in mesh with the side gears. While 
rotating them, install them into position.

3. Insert the pinion shaft.

4. Measure the backlash between the side gear and pinion.

Standard value: 
0.025 

− 0.150 mm (0.0010 − 0.0059 inch)

5. If the backlash is out of the standard value, select a spacer 

and re-measure the backlash.
NOTE: Adjust until the backlash on both sides are equal.
