GENERAL MAINTENANCE
(2006/01- )
1. INSPECT STEERING LINKAGE AND GEAR HOUSING
(a) Check the steering wheel free play.
(b) Check the steering linkage for looseness or
damage.
(1) Check that the tie rod ends do not have
excessive play.
(2) Check that the dust seals and boots are not
damaged.
(3) Check that the boot clamps are not loose.
(4) Check that the steering gear housing is not
damaged.
(5) Check that the connectors are properly
connected to the steering gear housing.
2. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
(1) Jack up the front of the vehicle and place
wooden blocks with a height of 180 to 200 mm
(7.09 to 7.87 in.) under the front tires.
(2) Lower the vehicle until the front coil spring has
about half its ordinary load. Place stands under
the vehicle for safety.
(3) Check that the front wheels are pointing
straight ahead. Use wheel chocks on all 4
wheels.
(4) Using a lever, pry up the end of the lower arm.
Check the amount of play.
Maximum ball joint vertical play:
0 mm (0 in.)
If there is any play, replace the ball joint.
(b) Check the dust cover for damage.
3. INSPECT DRIVE SHAFT BOOTS
(a) Check the drive shaft boots for loose clamps,
grease leakage, kinks or damage.
4. INSPECT AUTOMATIC TRANSAXLE FLUID LEVEL
(a) Visually check the transmission for fluid leakage. If
oil is leaking, find the cause and repair it.
5. INSPECT TRANSFER OIL (for 4WD)
(a) Visually check the transfer for oil leakage. If oil is
leaking, find the cause and repair it.
6. INSPECT REAR DIFFERENTIAL OIL (for 4WD)
(a) For the rear differential oil inspection, refer to the
following procedures (see page DF-3).

PROBLEM SYMPTOMS TABLE
(2006/01- )
HINT:
Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms are
listed in order of probability in the "Suspected Area" column
of the table. Check each symptom by checking the suspected
areas in the order they are listed. Replace parts as
necessary.

ON-VEHICLE INSPECTION
1. CHECK STEERING WHEEL FREE PLAY
(a) Stop the vehicle and align the tires facing straight
ahead.
(b) Turn the steering wheel gently right and left, and
check the steering wheel free play.
Maximum free play:
30 mm (1.18 in.)
If the free play exceeds the maximum, replace the
steering intermediate shaft sub-assembly or
steering gear.

REPAIR
1. CORRECT STEERING OFF CENTER
(a) Check whether the steering wheel is off-center.
(1) Apply masking tape to the top center of the
steering wheel and the upper steering column
cover.
(2) Drive the vehicle in a straight line for 100
meters at a constant speed of 56 km/h (35
mph), holding the steering wheel to maintain
the course.
(3) Draw a line on the masking tape, as shown in
the illustration.
(4) Turn the steering wheel to the center position.
HINT:
Look at the upper surface of the steering
wheel, the steering spokes and the SRS airbag
line to determine the center position.
(5) Draw another line on the masking tape on the
steering wheel, as shown in the illustration.
(6) Measure the distance between the 2 lines on
the masking tape on the steering wheel.
(7) Convert the measured distance to the steering
angle.
HINT:
• Measured distance of 1 mm (0.04 in.) =
Approximately 1 degree steering angle.
• Make a note of the steering angle.
(b) Adjust the steering angle.

POWER STEERING – ELECTRONIC POWER STEERING SYSTEMPS–5
PS
SYSTEM DESCRIPTION
1. DESCRIPTION
The EPS (Electronic Power Steering) system generates
torque through the operation of the motor and the
reduction gear installed on the column shaft in order to
assist steering effort.
The power steering ECU determines directions and the
amount of assisting power in accordance with vehicle
speed signals and signals from the torque sensor built
into the steering column assembly. As a result, the power
steering adjusts the steering effort so that it is lighter
during low speed driving and heavier during high speed
driving.
(a) Power steering ECU:
The power steering ECU calculates assisting power
based on steering torque signals from the torque
sensor and vehicle speed signals from the skid
control ECU.
(b) Torque sensor:
The torque sensor detects the steering effort
generated when the steering wheel is turned and
converts it to an electrical signal.
(c) EPS motor:
The EPS motor is activated by the current from the
power steering ECU and generates torque to assist
the steering effort.
(d) Motor rotation angle sensor:
The motor rotation angle sensor consists of the
resolver sensor, which excels in reliability and
durability. The rotation angle sensor detects the
rotation angle of the motor and outputs it to the
power steering ECU. As a result, it ensures efficient
EPS control.
