CUSTOMER INTERVIEW
Interview the customer if possible, to determine the c onditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer comments. Refer to RF-30, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that exist when the noise occurs.
 The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain all the facts and conditions that exist w hen the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is
concerned about. This can be accomplished by per forming a test drive with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so that the customer, service advis er, and technician use the same language when describing
the noise.
 Squeak – (Like tennis shoes on a clean floor)
Squeak characteristics include the light contact / fast movement / brought on by road conditions / hard sur-
faces = high-pitched noise / softer surfaces = low-pitched noises / edge to surface = chirping
 Creak – (Like walking on an old wooden floor)
Creak characteristics include firm contact / slow movement/twisting with a rotational movement / pitch
dependent on materials / often brought on by activity.
 Rattle – (Like shaking a baby rattle)
Rattle characteristics include fast repeated contact / vibr ation or similar movement / loose parts/missing clip
or fastener / incorrect clearance.
 Knock – (Like a knock on a door)
Knock characteristics include hollow sounds / someti mes repeating / often brought on by driver action.
 Tick – (Like a clock second hand) Tick characteristics include gentle contacting of light materials / loose components / can be caused by driver
action or road conditions.
 Thump – (Heavy, muffled knock noise) Thump characteristics include softer knock / dull sounds often brought on by activity.
 Buzz – (Like a bumblebee)
Buzz characteristics include high frequency rattle / firm contact.
 Often the degree of acceptable noise level varies depending upon the person. A noise that a technician may
judge as acceptable may be very irritating to a customer.
 Weather conditions, especially humidity and temperat ure, may have a great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when the repair is reconfirmed.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document t he facts and conditions when the noise occurs and any of
customer's comments; refer to SE-103, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that exist when the noise occurs.
 The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain all the facts and conditions that exist when the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is
concerned about. This can be accomplished by performing a cruise test on the vehicle with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
 Squeak – (Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping
 Creak – (Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
 Rattle – (Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
 Knock – (Like a knock on a door)
Knock characteristics include hollow sounding/someti mes repeating/often brought on by driver action.
 Tick – (Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loose components/can be caused by driver
action or road conditions.
 Thump – (Heavy, muffled knock noise) Thump characteristics include softer k nock/dead sound often brought on by activity.
 Buzz – (Like a bumblebee)
Buzz characteristics include high frequency rattle/firm contact.
 Often the degree of acceptable noise level will vary depending up on the person. A noise that a technician may judge as acceptable may be very irritating to the customer.
 Weather conditions, especially humidity and temperat ure, may have a great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when the repair is reconfirmed.

4. Disconnect the spiral cable body side harness connectors (A) and steering angle sensor harness connector (B).
5. Remove the spiral cable fixing screws.
6. Pull out forward the spiral cable and steering sensor.
7. Remove steering angle sensor. Refer to BRC-139, "
Removal and Installation".
CAUTION:
 Never impact the spiral cable.
 Replace the spiral cable if it has been dropped or sustained
an impact.
 Never disassemble the spiral cable.
 Never apply lubricant to the spiral cable.
 Never allow oil, grease, detergent, or water to come in contact with the spiral cable.
INSTALLATION
Note the following item, and install in the reverse order of removal.
CAUTION:
 The spiral cable may snap during steering operation if the
cable is installed in an improper position.
The neutral position is set as follows.
 Carefully turn the spiral cable clockwise to the end position.
Then turn it counterclockwise (a bout 2 and a half turns) and
stop turning at the mark (B) on which the stopper insertion
holes are in the same position.
 The service part is installed in the neutral position by the
stopper and can be set without adjusting after the stopper is
removed.
 Never over turn the spiral cable or go beyond the number of
turns required. (These will cause the cable to snap.)
 Adjust the spiral cable locatin g pin (A) to the steering wheel
locating pin hole (C).

a. Measure pinion rotating torque within ±180 ° of neutral position
of the rack assembly using Tools. Stop the gear at the point
where highest torque is read.
b. Loosen adjusting screw lock nut and adjusting screw and then retighten to 5.4 N·m (0.55 kg-m, 48 in-lb), and then loosen by 20
to 40 °.
c. Measure pinion rotating torque using tools to make sure that the measured value is within the standard. Readjust if the value is
outside the standard. Replace steering gear assembly, if the
value is outside the standard after readjusting, or adjusting
screw rotating torque is 5 N·m (0.51 kg-m, 44 in-lb) or less.
d. Apply thread locking sealant to inner socket and turn pinion fully to left with inner socket installed to gear housing assembly.
e. Install dial gauge at 5 mm (0.20 in) (L) from the edge of gear housing assembly (1), and tooth point.
f. Measure vertical movement of rack assembly when pinion is turned clockwise with torque of 19.6 N·m (2.0 kg-m, 14 ft-lb).
Readjust adjusting screw angle if the measured value is outside
the standard.
 If reading is outside of the specification, readjust screw angle
with adjusting screw.
CAUTION:
 If reading is still outside of sp ecification, or if the rotating torque of adjusting screw is less
than 5 N·m (0.51 kg-m, 44 in-lb), replace steering gear assembly.
 Never turn adjusting scr ew more than twice.
 Replace steering gear assembly when adjusting screw is removed or turned more than twice.
