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

Reposition

Loose gear box bracket

Retighten

Loose tie rod end and/or ball joint

Retighten

SERVICE ADJUSTMENT PROCEDURE

CHECKING STEERING WHEEL FREE PLAY 

1. Start the engine and with the steering wheel in the straight ahead position.  

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.

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.
