Vehicle Inspection
There is some noise in all power steering systems. One of the most common is a hissing sound. Hiss is a high
frequency noise similar to that of a water tap being closed slowly. The noise is present in all valves that have a high
velocity steering fluid passing through an orifice. There is no relationship between this noise and steering perfor-
mance. The hissing sound is commonly heard during the following operations:
•Evident at a standstill
• At park with the engine running
• When the steering wheel is at the end of its travel

Removal & Installation
WARNING!
Before servicing the steering column, the airbag system must be disarmed. Failure to do so may result in acci-
dental deployment of the airbag and possible personal injury (See Airbag System Disarming Procedure in Sec-
tion 14 Restraints).
NOTE :
To help maintain alignment of the spiral cable connector during reassembly, apply a small piece of tape to the spiral
cable and the steering column to keep them in alignment.1. Set the front wheels to the straight-ahead position.
2. Disconnect the negative battery cable.
3. Remove the driver airbag (See Driver Airbag Removal & Installation in Section 14 Restraints).
4. Disconnect the spiral cable electrical connector.
5. Remove the steering wheel lock nut (1). (Tighten: Steering wheel lock nut to 25 - 30 N·m)
6. Using the steering wheel puller, remove the steer- ing wheel.
7. Installation is in the reverse order of removal.
Installation Notes:
• The spiral cable could be damaged if installed in an improper position.
• Do not rotate the spiral cable quickly or beyond the limit of turns (this can cause the cable to snap).
• Verify the airbag system is operating properly after the repair is complete.

Steering Wheel Free-Play Inspection
•Set the front wheels to the straight-ahead position with the engine idling (hydraulic system is working).
• Slightly turn steering wheel to the right and left, and before the wheels begin turning, measure the free play of
steering wheel.
Maximum limit: 40 mm.
• If the free play exceeds the limit value, inspect the gap between the steering shaft joint and the steering link-
age. Repair or replace the related parts as necessary. If the free play still exceeds the limit value, turn the
steering wheel to the right position with the engine off. Apply 5 N·m of load to the steering wheel and inspect
the free-play again.
Standard value: Less than 15 mm (steering wheel free play with the engine off)
• If free play exceeds standard value, remove steering gear housing and inspect the gross torque of pinion gear.
Static Steering Force Inspection
•Park the vehicle on a level surface, and turn the steering wheel to the straight-ahead position. Start the engine,
adjust engine speed to 1000 ± 100 RPM.
CAUTION:
After adjusting the engine speed, return it back to standard idle speed.
•Connect a spring scale to the outer circle of steering wheel. Measure the steering force required when turning
the steering wheel leftward and rightward (within 1.5 circles) at the straight-ahead position. If obvious steering
force fluctuation exists, inspect the steering force as necessary.
Standard steering force: Less than 34 N·m
Fluctuation tolerance: Less than 5.9 N·m
• If the measured force exceeds the standard value, see the trouble shooting section for inspection and adjust-
ment.

NOTE :
This test should be performed during a road test.
•Make smooth turns and sharp turns. Check the driving senseto ensure there is no difference between the left
and right turns in terms of steering force and the steering wheel returning to center.
• When the vehicle speed is between 20 to 30 km/h, turn the steering wheel 90° for 1 or 2 seconds and release
the steering wheel. If the steering wheel returns
over 70°, the steering wheel return function can be
considered good.
NOTE :
When rapidly turning the steering wheel, there will be a sense of “heavy”, however, this does not indicate a problem
with the steering system. This is due to insufficient steering fluid supplied to the steering fluid pump during idle
speed.

Description
The steering gear used is the rack-and-pinion type with power assist. It is mounted on the front suspension sub-
frame. The outer ends of the outer tie rods attach to the front knuckles.
NOTE :
The power steering gear should not be serviced or adjusted. If a malfunction or steering fluid leak occurs with the
steering gear, the complete steering gear needs to be replaced.
Operation
The steering wheel turns the pinion. The rack is a long flat bar with geared teeth on one side. The rack teeth mesh
with the teeth on the pinion gear. Rotation of the pinion moves the rack from left to right and right to left. The tie rod
then causes the wheels to turn to the left or right.
