7. Set the SSTs as shown in Fig. 35 .  

8. Place the measuring probe of the dial gauge at the point where the side bearing is installed in the 

differential carrier and measure at the lowest position. Measure the left and right sides.

9. Add the two (left and right) values obtained by the measurements taken in Step 8 and then divide the total 

by 2 . From this sum, subtract the sum of the number inscribed on the end of the drive pinion divided by 
100 . (If there is no figure inscribed, use 0.) This is the pinion height adjustment value. 

Differential pinion height  

0.038 mm {0.0015 in} or less  

SPACER TABLE 

REAR BEARING ASSEMBLY NOTE 

1. Assemble the spacer selected in the pinion height adjustment to the drive pinion.  

2. Press the drive pinion into the rear bearing using the SSTs and a press. 

NOTE:

When the values obtained by the measurements taken in Step 8, 9 
are 0.06 mm {0.0024 in}, 0.04 mm {0.0016 in} and the tip surface of the 
drive pinion value is 2, the formula is ((0.06+0.04)/2)-(2/100)=0.03. 
Therefore, assemble a spacer 0.03 mm {0.0012} thicker than the 
currently assembled one. The thickness settings are in increments of 
0.015 mm {0.0006}, so choose one closest in thickness and install.
