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.
Pinion height
–0.025—0.025 mm {–0.001—0.001 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)
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), 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

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.

the differential carrier with the spacer installed.
This is value B.
5. The combined thickness of the left and right
adjusting shims is obtained by the following
formula.

2 = B – A + 0.44 mm {0.017 in}
6. If the combined thickness of the previously
installed adjusting shims is between C1 and C2,
use the shims as they are.
7. If the combined thickness of the previously
installed adjusting shims is not between C1 and

around the ring gear, and check that the tooth
contacts showing the red lead coating are the
same as the pattern indicated in the figure.
•If the tooth contact is good, wipe off the
red lead coating.
•If it is not good, adjust the pinion height,
then adjust the backlash.
(4) If toe and flank contact appears as shown in
the figure, replace the spacer with a thinner
one, and move the drive pinion outward.
(5) If heel and face contact appears as indicated
in the figure, replace the spacer with a thicker
one and move the drive the pinion inward.

SUSPENSION CONTROL SYSTEMA6E741601013201Outline
•The self-leveling suspension is a system that adjusts the vehicle height according the amount of vehicle load.
This system will raise the rear of a vehicle, lowered due to a load placed on it, to the designated load level
* after
the vehicle has been driven a certain distance.
•The vehicle height adjustment is performed using a gas-pressurized pump function built into the rear shock
absorber.
•For the vehicle height to return to the designated load level, the vehicle must be driven approx. 5—6 km {3.1—
3.7 miles} in city driving conditions. (Distance will vary due to load and road conditions.)
•A load amount of approx. 140—300 kg {308—660 lb} at the rear axle will cause the vehicle height to be raised,
and any weight over that will prevent the vehicle from returning to the designated load level.
*: Designated load level is defined as the level at which the vehicle is with: a full fuel tank; engine coolant and oil at
specified levels; spare tire, jack and tools in designated positions; and four people, weighing 55 kg {121 lb} each,
riding in the vehicle.

Operation
During leveling operation
•During shock absorber expansion, the inlet check valve opens due to negative pressure created in the pump
chamber, and oil is drawn into the pump chamber from the low-pressure chamber. During shock absorber
contraction, oil pressure in the pump chamber forces the outlet check valve to open, and oil in the pump
chamber flows through the pump cylinder into the high-pressure chamber. Due to this expansion and
contraction while driving, rod reaction force increases, and the vehicle height returns to the designated load
level. Also, similar to a regular shock absorber, damping is performed while driving with the damping valve.
.
Leveling operation completed
•When the vehicle height returns to the designated
load level, the volume of oil in the high-pressure
chamber increases and the piston rises. This
causes the pump chamber and the high-pressure
chamber to be connected at the pump rod notch,
and the expansion or contraction is completed.
