Noise

Hissing Noise in Steering Gear
There is some noise with all power steering systems. One of the most common is a
hissing sound when the steering wheel is turned and the car is not moving. This noise
will be most evident when turning the wheel while the brakes are being applied.
There is no relationship between this noise and steering performance. Do not replace
the valve unless the "hissing" noise becomes extreme. A replaced valve will also
make a slight noise, and is not always a solution for the condition.

Rattling or
chucking noise in
the rack and pinion

Interference with hoses from vehicle body

SERVICE ADJUSTMENT PROCEDURE

CHECKING STEERING WHEEL FREE PLAY

2. Measure the play while turning the steering wheel to the left and right.

Standard value:

Steering wheel free play: 30 mm (1.1 in)

3. If the play exceeds the standard value, inspect the connection between the steering shaft and tie rod ends.

CHECKING STEERING ANGLE

1. Place the front wheel on a turning radius gauge and measure the steering angle.

STEERING ANGLE

STEERING ANGLE SPECIFICATION

2. If the measured value is not within the standard value, adjust the toe and inspect again.

Inner

38.64°

Outer

3. If the starting torque exceeds the upper limit of the standard value, replace the tie rod end.

4. Even if the starting torque is below the lower limit of the standard value, check the play of the ball joint

and replace if necessary.

STEERING WHEEL RETURN

1. The force required to turn the steering wheel and the wheel return should be the same for both moderate

and sharp turns.

2. When the steering wheel is turned 90° and held for a couple of seconds while the vehicle is being driven

at 20-30 kph (12-19 mph), the steering wheel should return at least 20° from its central position when it is
released.

NOTE:

If the steering wheel is turned very quickly, steering may be momentarily
difficult. This is not a malfunction because the oil pump output will be
somewhat decreased.
