ON-VEHICLE SERVICE
WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
Measure the wheel alignment with the vehicle parked on a
level surface.
The front suspension, steering system, and wheels should be
serviced to normal condition prior to measurement of wheel
alignment.
TOE-IN
Standard value:
At the centre of tyre tread 0±2mm
Toe angle (per wheel) 0_00’±05’
1. Adjust the toe-in by undoing the clip and lock nut, and
turning the left and right tie rod turnbuckles by the same
amount (in opposite directions).
NOTE
The toe will move out as the left turnbuckle is turned
toward the front of the vehicle and the right turnbuckle
is turned toward the rear of the vehicle.
2. Install the clip and tighten the lock nut to the specified torque.

3. Confirm that the toe-in is at the standard value.
4. Use a turning radius gauge to check that the steering
angle is at the standard value.

TOE-OUT ANGLE ON TURNS
To check the steering linkage, especially after the vehicle
has been involved in an accident or if an accident is presumed,
it is advisable to check the toe-out angle on turns in addition
to the wheel alignment.
Conduct this test on the left turn as well as on the right turn.

REMOVAL AND INSTALLATION
Caution
1. Before removing the steering wheel and air bag module assembly, refer to GROUP 52B - Service
Precautions and Air Bag Module and Clock Spring. Also, put the front wheels in straight-ahead
position. Failure to do so may damage the SRS clock spring and render the SRS air bag
inoperative, which results serious driver injury.
2. If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to
contact the parts or tools to the caliper because the paint of caliper will be scratched. And
if there is brake fluid on the caliper, wipe out quickly.
3. To prevent bushings from breakage, the parts indicated by * should be temporarily tightened,
and then fully tightened with the vehicle on the ground in the unladen condition.

Caution
1. To prevent the ball joint thread from damage, the tie
rod end mounting nut must be only loosened but not
removed from the ball joint. Be sure to use the special
tool.
2. Support the special tool with a cord to prevent it from
coming off.
AB"FIXTURE/BUSHING/STABILIZER BAR REMOVAL
Carry out the following operations to ensure working space
in order to remove the fixture, the bushing and the stabilizer
bar.
1. Use a transmission jack to hold the crossmember, and
then remove the crossmember mounting nuts and bolts.
2. Lower the crossmember until the fixture, the bushing and
the stabilizer bar can be removed.
Caution
Be careful not to lower the crossmember excessively,
otherwise the power steering return hose bracket may
deform.

ABS <4WD> -General Information35B-2
GENERAL INFORMATION
ABS has been adopted as optional equipment in
RS-IIto maintain directional stability and steering
performance during sudden braking or braking on
slippery road surfaces.
The ABS control method is a 4-sensor, 4-channel
method which provides independent control for all
wheels.
Following system for Lancer EVOLUTION-VII has
been modified from Lancer EVOLUTION-VI Tommi
Makinen Edition.DBy adding lateral G sensor, longitudinal G
sensor and steering wheel sensor, optimized
ABS control at the time of cornering.
DBy inputting parking brake switch signal to
ABS-ECU with pulling parking brake lever, ABS
control has been optimized.
DABS-ECU outputs ABS signal to 4WD-ECU.
DG sensor (lateral), steering wheel sensor and
parking brake switch have been added to the
diagnosis and service data.
DABS-ECU connector has been changed.
EBD CONTROL
In ABS, electronic control method is used by which
the rear wheel brake hydraulic pressure during
braking is regulated by rear wheel control solenoid
valves in accordance with the vehicle’s rate of
deceleration and the front and rear wheel slippage
which are calculated from the each wheel speed
sensor’s signal. EBD control is a control system
which provides a high level of control for both vehicle
braking force and vehicle stability. The system has
the following features:
DBecause the system provides the optimum rear
wheel braking force regardless of the vehicleladen condition and the condition of the road
surface, the system reduces the required pedal
depression force, particularly when the vehicle
is heavily laden or driving on road surfaces
with high frictional coefficients.
DBecause the duty placed on the front brakes
has been reduced, the increases in pad
temperature can be controlled to improve the
wear resistance characteristics of the pad,
during front brakes applying.
DControl valves such as the proportioning valve
are no longer required.
