3A-8 FRONT ALIGNMENT
Toe-in Adjustment
Measurement should be taken with the vehicle on a surface
plate.
If a surface plate is not available, toe-in should be checked
with the vehicle parked on a level floor.
1. Set front wheels to straight ahead position.
2. Align the toe-in gauge with center height of each wheel at front end.
3.
Apply center marks to each wheel, then take measurement
of distance A between the center marks on each wheel.
4. Slowly move the vehicle rearward until the center marks reach the rear end position.
5. Take measurement of distance B between the cente
r
marks at rear end.
The toe-in can be calculated with the following formula.
Toe-in = B - A

To adjust the toe-in angle, loosen the lock nuts (2) on the tie

to keep the steering wheel centered.

3B-6 POWER-ASSISTED STEERING SYSTEM
Steering Column
RTW 53BLF000901
WARNING: TO AVOID DEPLOYMENT WHEN
TROUBLE-SHOOTING THE SRS SYSTEM, DO NOT
USE ELECTRICAL TEST EQUIPMENT, SUCH AS
A
BATTERY-POWERED OR A/C-POWERED
VOLTMETER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN SPECIFIED
IN THIS MANUAL. DO NOT USE A NON-POWERED
PROBE-TYPE TESTER.
INSTRUCTIONS IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PERSONAL
INJURY MAY RESULT.
W hen servicing a vehicle equipped with a Supplemental
Restraint System, pay close attention to all W ARNINGS
and CAUTIONS.
For detailed explanations about SRS, refer to Restraints
section.
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted conveniently on the column.
3. W ith the column mounted lock, the ignition and steering operation can be locked to prevent theft o
f
the vehicle.
The column can be disassembled and reassembled.
However, to insure the energy absorbing action, use
only the specified screws, bolts and nuts as designated,
and tighten them to the specified torque.
Handle the column with care when it is removed from
the vehicle. A sharp blow on the end of the steering
shaft or shift lever, or dropping the assembly could
shear or loosen the fasteners that maintain column
rigidity.

4. Install all the lines and hoses. Fill the system with
new power steering fluid and bleed the system as
described in Bleeding the Power Steering System.
Operate the engine for about 15 minutes.
Remove the pump return line at the pump inlet and
plug the connection on the pump. W hile refilling the
reservoir, check the draining fluid for contamination.
If foreign matter is still evident, replace all lines,
disassemble and clean or replace the powe
r
steering system components. Do not re-use any
drained power steering fluid.
Steering Wheel Free Play Inspection
RTW 73BSH000901
1. W ith the tires in the straight-ahead position, check the amount of steering wheel play by turning the
wheel in both directions until the tires begin to move.
NOTE: The wheel free play should be checked with the
engine running. Free play: 0 - 30 mm (0 - 1.18 in)
2.
Also check the steering wheel for play and
looseness in the mount by moving it back and forth
and sideways. W hen test driving, check for hard
steering, steering shimmy and tendency to pull to
one side.
Front End Alignment Inspection and
Adjustment
Toe-in Adjustment
Toe-in: Refer to Section 3A FRONT ALIGNMENT
1. To adjust the toe-in angle, loosen the lock nuts (2) on the tie rod (1) and turn the tie rod. Turn both rods
the same amount, to keep the steering wheel
centered .
