Disassembly

• If the disassembly procedure is complex,

requiring many parts to be disassembled, all parts
should be marked in a place that will not affect
their performance or external appearance, and
identified so that reassembly can be performed
easily and efficiently.

Inspection During Removal, Disassembly

• When removed, each part should be carefully

inspected for malfunction, deformation, damage
and other problems.

Arrangement of Parts

• All disassembled parts should be carefully

arranged for reassembly.

• Be sure to separate or otherwise identify the parts

to be replaced from those that will be reused.

Cleaning of Parts

• All parts to be reused should be carefully and

thoroughly cleaned in the appropriate method.

Warning

• Using compressed air can cause dirt and

other particles to fly out causing injury to
the eyes. Wear protective eye wear
whenever using compressed air.

Reassembly

• Standard values, such as torques and certain

adjustments, must be strictly observed in the
reassembly of all parts.

• If removed, these parts should be replaced with

new ones:

— Oil seals

— Gaskets

— O-rings

— Lock washers

— Cotter pins

— Nylon nuts

• Depending on location:

— Sealant and gaskets, or both, should be

applied to specified locations. When sealant
is applied, parts should be installed before
sealant hardens to prevent leakage.

— Oil should be applied to the moving

components of parts.

— Specified oil or grease should be applied at

the prescribed locations (such as oil seals)
before reassembly.

Adjustment

• Use suitable gauges and testers when making

adjustments.

Rubber Parts and Tubing

• Prevent gasoline or oil from getting on rubber

parts or tubing.

Hose Clamps

• When reinstalling, position the hose clamp in the

original location on the hose and squeeze the
clamp lightly with large pliers to ensure a good fit.

Torque Formulas

• When using a torque wrench-SST or equivalent

combination, the specified torque must be
recalculated due to the extra length that the SST
or equivalent adds to the torque wrench.
Recalculate the torque by using the following
formulas. Choose the formula that applies to you.

A : The length of the SST past the torque wrench drive.
L : The length of the torque wrench.

Vise

• When using a vise, put protective plates in the

jaws of the vise to prevent damage to parts.

Dynamometer

• When inspecting and servicing the power train on the dynamometer or speedometer tester, pay attention to the

following:

— Place a fan, preferably a vehicle-speed proportional type, in front of the vehicle.

— Make sure the vehicle is in a facility with an exhaust gas ventilation system.

— Since the rear bumper might deform from the heat, cool the rear with a fan. (Surface of the bumper must be

below70

°C {158°F} degrees.)

— Keep the area around the vehicle uncluttered so that heat does not build up.

— Watch the water temperature gauge and do not overheat the engine.

— Avoid added load to the engine and maintain normal driving conditions as much as possible.

Note

• When only the front or rear wheels are rotated on a chassis dynamometer or equivalent, the DSC CM

determines that there is a malfunction in the DSC and illuminates the following lights:

— ABS warning light

— Brake system warning light

— DSC indicator light

• If the above lights are illuminated, dismount the vehicle from the chassis dynamometer and turn the

ignition switch to the LOCK position. Then, turn the ignition switch back to the ON position, run the vehicle
at 10 km/h or more and verify that the warning lights go out. In this case, a DTC will be stored in the
memory. Clear the DTC from the memory by following the memory clearing procedure [DSC] in the on-
board diagnostic system. (See04-02-3 ON-BOARD DIAGNOSIS.)

AWD inspection/service
Speedometer tester measurement

Caution

• Install the tension bar (chain wire) to the tie down hook and secure the vehicle to prevent it from

rolling and running off.

• Do not accelerate suddenly from a standstill or accelerate/decelerate rapidly.

Free roller type

1. Align the free rollers with the wheel base and tread, then set them on the floor properly.
2. Drive the vehicle slowly onto the tester roller and

free rollers.

3. Start the engine and accelerate gradually to

inspect the speedometer.

4. After inspection, decelerate gradually with gentle

braking.

Propeller shaft removal type

1. Remove the propeller shaft.

(See03-15-3 PROPELLER SHAFT REMOVAL/
INSTALLATION.)

2. Place the front wheels on the tester roller.
3. Accelerate gradually and inspect the

speedometer.

4. After inspection, decelerate gradually with gentle

braking.

5. Install the propeller shaft.

(See03-15-3 PROPELLER SHAFT REMOVAL/
INSTALLATION.)

Brake tester measurement

1. Place the wheels (front or rear) to be measured

on the tester roller.

2. Shift to the N position/neutral.
3. Activate the tester roller and measure braking

force. If there is a large amount of brake drag
force, the electronic control system coupling may
be affected. Jack up all four wheels to eliminate
the effect of the coupling and rotate each wheel
by hand to verify the rotation condition.
