7. Set the SST as shown in the figure.

8. Place the measuring probe of the dial indicator so that it contacts the place where the side bearing is

installed in the carrier. Then measure the left and right side of the lower position.

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 result, subtract the result obtained by dividing the number inscribed on the end surface of
the drive pinion by 100. (If there is no figure inscribed, use 0.) This is the pinion height adjustment value.

Rear differential pinion height -0.032-0.032 mm {-0.0012-0.0012 in}

NOTE:



For example, the measured results obtained at Step 8 and 9 are 0.06
mm {0.003 in} and 0.04 mm {0.002 in}, and the figure inscribed on the
end of the drive pinion is 2: ((0.06 mm {0.003 in}+0.04 mm {0.002 in}) /
2) - (2/100) = 0.03 mm {0.001 in} (pinion height adjustment value)

Spacer thickness

SPACER THICKNESS SPECIFICATION

10. Assemble the spacer selected for the pinion height adjustment to the drive pinion.

11. Press the bearing inner race (rear bearing) into the drive pinion using the SSTs and a press.

Substitution SST



49 V001 525

Outer diameter: 37.2-50.3 mm {1.47-1.98 in}

Inner diameter: 35.2 mm {1.39 in} or more

Inner depth: 134.3 mm {5.29 in} or more

Plate thickness: 1 mm {0.04 in} or more

Replace with a spacer 0.03 mm {0.001 in} thicker than the currently
used one. Spacer thickness is set at 0.015 mm {0.0006 in}
increments, therefore select the closest spacer thickness and
assemble.



Install the spacer with the chamfer on the SST side.

LOCKNUT ASSEMBLY NOTE

Drive pinion preload adjustment

1. Apply differential oil to a new locknut.

2. Assemble a new collapsible spacer, bearing inner race (front bearing), spacer and locknut to the drive

pinion, and temporarily tighten the locknut.

3. Turn the serrated part of the drive pinion by hand to seat the bearing.

4. Tighten the locknut temporarily tightened in Step 1 from the lower limit of the specified tightening torque

using the SSTs , and make this the specified preload.



If the specified preload cannot be obtained within the specified tightening torque, replace the
collapsible spacer and inspect again.

Tightening torque 240-755 N.m {24.5-76.9 kgf.m, 177-556 ft.lbf}

Rear differential drive pinion preload 1.3-1.8 N.m {13.3-18.2 kgf.cm, 11.5-15.9 in.lbf}

5. Crimp the locknut using a chisel and hammer.
