INSTALLATION
1) Check that vehicle's front tires are at straight-ahead position and
contact coil is centered. Refer to ªCENTERING CONTACT
COILº in this section.
CAUTION:
These two conditions are prerequisite for installation of
steering wheel. If steering wheel has been installed with-
out these conditions, contact coil will break when steer-
ing wheel is turned.
2) Install steering wheel to steering shaft with 2 lugs on contact coil
fitted in two grooves in the back of steering wheel and also align-
ing marks on steering wheel and steering shaft.
3) Tighten steering shaft nut to specified torque.
Tightening Torque
(a): 33 N
.m (3.3 kg-m, 23.5 lb-ft)
4) Install driver air bag (inflator) module to steering wheel. Refer to
ªDRIVER AIR BAG (INFLATOR) MODULEº in this section.
CONTACT COIL AND COMBINATION SWITCH
ASSEMBLY
CAUTION:
Do not turn contact coil (on combination switch) more than
allowable number of turns (about two and a half turns from
the center position clockwise or counterclockwise respec-
tively), or coil will break.
REMOVAL
1) Remove steering wheel from steering column. Refer to
ªSTEERING WHEELº in this section.
2) Remove steering column hole cover.
3) Remove steering column cover screws (3 pieces).
4) Separate upper cover and lower cover, then remove them.
5) Disconnect all connectors for contact coil and combination
switch assembly.

INSPECTION
Check contact coil and combination switch wire harness for any
signs of scorching, melting or other damage. If it is damaged, re-
place.

2) Disable air bag system. Refer to ªDISABLING AIR BAG SYS-
TEMº under ªSERVICE PRECAUTIONSº in Section 10B.
3) Remove steering wheel and contact coil and combination switch
assembly, if necessary. Refer to ªSTEERING WHEELº and
ªCONTACT COIL AND COMBINATION SWITCH ASSEMBLYº
in this section.
Perform the following procedure if not removing steering wheel
and/or combination switch.
ii) Turn steering wheel so that vehicle's front tires are at straight-
ahead position.
ii) Turn ignition switch to ªLOCKº position and remove key.
4) Remove steering column hole cover.
5) Disconnect all connectors for the following parts.
Contact coil and combination switch
Ignition switch
6) Make alignment marks on shaft joint and shaft (column side) for
a guide during reinstallation.

4) Check steering column lower seal for breakage or deformation.
If found defective, replace.
5) Check steering shaft joints and shaft for any damages such as
crack, breakage, malfunction or excessive play.
If anything is found faulty, replace as steering lower shaft assem-
bly or steering column assembly.
6) Check steering shaft for smooth rotation.
If found defective, replace as column assembly.
7) Check steering shaft and column for bend, cracks or deforma-
tion.
If found defective, replace as column assembly.
INSTALLATION
CAUTION:
After tightening steering column mounting bolts, steering
shaft joint bolts should be tightened.
1) Be sure that front wheels and steering wheel are in straight-
ahead position.
2) If equipped with shift (key) interlock cable, install shift (key) inter-
lock cable to ignition switch.

lock assembly from steering column.
INSTALLATION
1) Position oblong hole of steering shaft in the center of hole in col-
umn.
2) Turn ignition key to ªACCº or ªONº position and install steering
lock assembly onto column.
3) Now turn ignition key to ªLOCKº position and pull it out.
4) Align hub on lock with oblong hole of steering shaft and rotate
shaft to assure that steering shaft is locked.
5) Tighten new bolts until head of each bolt is broken off.
6) Turn ignition key to ªACCº or ªONº position and check to be sure
that steering shaft rotates smoothly. Also check for lock opera-
tion.

Should it have been turned and contact coil (on combina-
tion switch) have got out of its centered position, it needs
to be centered again. Also, turning steering wheel more
than about two and a half turns will break contact coil.
REMOVAL
1) Turn steering wheel so that vehicle's front tires are at straight-
ahead position.
2) Turn ignition switch to ªLOCKº position and remove key.
3) After removing bolt on column side of shaft joint and loosening
bolt on its lower shaft assembly side, move shaft joint to lower
shaft assembly side (in arrow direction in figure).
4) Remove lower shaft assembly lower joint bolt and then remove
lower shaft assembly.
5) Remove shaft joint bolt (lower shaft assembly side) from shaft
joint and then remove shaft joint from lower shaft assembly.

CLEARANCE BETWEEN BOOSTER PISTON ROD AND
MASTER CYLINDER PISTON ADJUSTMENT
The length of booster piston rod is adjusted to provide specified
clearance ªaº between piston rod end and master cylinder piston.
Before measuring clearance, push piston rod several times so as
to make sure reaction disc is in place.
Keep inside of booster at atmospheric pressure for measure-
ment.
1) Set special tool (A) on master cylinder and push pin until con-
tacts piston.
Special Tool
(A): 09950-96010
2) Turn special tool upside down and place it on booster. Adjust
booster piston rod length until rod end contacts pin head.
Special Tool
(A): 09950-96010
Clearance ªbº: 0 mm (0 in.)
NOTE:
Take measurement with booster set vertically and rod at the
center.
3) Adjust clearance by turning adjusting screw of piston rod.
Special Tool
(F): 09952-16010
Reference
When adjusted as above, its negative pressure is applied to boost-
er with engine at idle, piston to piston rod clearance ªaº should be-
come below.
Clearance ªaº: 0.25 ± 0.5 mm (0.010 ± 0.020 in.)
