SERVICE POINTS OF REMOVALM37GBAV1. REMOVAL OF AIR BAG MODULE
(1) Remove the air bag module mounting nut using a
socket wrench from the back side.
(2) To remove the clock spring connector (squib connector)
from the air bag module, force the lock outward and pry
it with a standard screwdriver, as shown in the
illustration at the left, to make sure that no undue force
is exerted to the connector when it is removed.
CautionWait at least 30 seconds after disconnecting the
battery cable before doing any further work. The
SRS system is designed to retain enough voltage todeploy the air bag for a short time even after the
battery has been disconnected, so serious injury
may result from unintended air bag deployment if
work is done on the SRS system immediately afterthe battery cable is disconnected.
(3) The removed air bag module should be stored in a
clean, dry place with the pad cover face up.
2. REMOVAL OF STEERING WHEEL
Remove the steering wheel by using a steering wheel
puller.
CautionDo not hammer on the steering wheel to remove it;
doing so may damage the collapsible mechanism.
SERVICE POINT OF INSTALLATIONM37GDAR2. INSTALLATION OF STEERING WHEEL
Line up the “NEUTRAL” mark of the clock spring with the
mating mark before installing the steering wheel.
CautionIf the clock spring’s mating mark is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal
operation of the SRS and possibly leading to serious
injury to the vehicle’s driver.1

CautionWhen removing the gear box, pull it out carefully
and slowly to avoid damaging the boots.
INSPECTIONM37PCAFGEAR BOX FOR TOTAL PINION TORQUE
Using the special tools, rotate the pinion gear at the rate of one
rotation in approximately 4 to 6 seconds to check the total
pinion torque.
Standard value: 0.6
- 1.3 Nm (5 - 11 in.lbs.)
NOTEMeasure the pinion torque through the whole stroke of the
rack.If the measured value is not within the standard range, first
adjust the rack support cover, and then check the total pinion
starting torque again.
If the total pinion starting torque cannot be adjusted to within
the standard range by adjusting the rack support cover, check
the rack support cover, rack support spring, rack support and
replace any parts necessary.
CHECK THE TIE ROD FOR SWING RESISTANCE
(1) Give
10 hard swings to the tie rod.
(2) Measure the tie rod swing resistance with a spring balance
Standard value: 8
- 18 N (1.8 - 4.0 Ibs.)
[2 - 5 Nm (17 - 43 in.lbs.)](3) If the measured value exceeds the standard value, replace
tie rod assembly.
NOTEEven if the measured value is below the standard value, the
tie rod which swings smoothly without excessive play may
be used.
