CHECKING CONDITION OF INSTALLATION
• Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.
• Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
• Check steering gear assembly bolts and nuts for looseness. Refer to PS-15, "
Removal and Installation".
CHECKING STEERING WHEEL PLAY
• Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on the
outer circumference.
• When the measurement value is outside the standard val ue, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL
• Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the correct position.
• Perform neutral position inspection after wheel alignment. Refer to PS-2, "
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"".
• Set vehicle to the straight-ahead position and c onfirm steering wheel is in the neutral position.
• Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if steer-
ing wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position using
Tool as shown.
4. If steering wheel turning force is out of the specification, refer to GI-9, "
How to Follow Trouble Diagnosis".

Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 - 35 mm (0 - 1.38 in)

STEERING WHEEL
CAUTION:
• After installing steering wheel, perform wheel alignment. Refer to FSU-7, "
Wheel Alignment Inspec-
tion".
REMOVAL
NOTE:
When reconnecting spiral cable, secure cable with a tape so that case and rotating part keep aligned. This will
omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer to SRS-34, "
Removal and Installation".
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel.
INSTALLATION
Installation is in the reverse order of removal.
1. Steering wheel 2. Steering column assembly (with mo-
tor, reduction gear, sensor) 3. Bracket
4. EPS control unit 5. Intermediate shaft

• Align spiral cable correctly when installing steering wheel. Make sure spiral cable alignment and centering marks (B) are matched
and in the neutral position. The neutral position is detected by turn-
ing left 2.5 revolutions from the right end position, ending with the
locating pin (A) at the top. Place steering wheel in straight ahead
position, then install it with the locating pin hole (C) directly over
spiral cable locating pin.
• After the work is completed, perform self-diagnosis to make sure no malfunction is detected. Refer to SRS-19, "
SRS Operation
Check".
• Tighten steering wheel lock nut to specification.

CAUTION:
Clean steering gear assembly with kerosene before disassembling.
DISASSEMBLY
1. Loosen outer socket lock nut, and then remove outer socket from inner socket.
2. Remove boot clamp, and then remove boot from inner socket.
CAUTION:
Do not damage inner socket and gear housin g assembly when removing boot. Inner socket and
gear housing assembly must be replaced if inne r socket and gear housing assembly are damaged
because it may allow foreign material to enter.
3. Remove inner socket from rack assembly while holding the flat portion of the rack next to the inner socket using a suitable tool.

4. Measure adjusting screw height “H”, and loosen lock nut (2).
5. Remove adjusting screw (1), retainer (3) and spring (4) from gear housing assembly (5).
INSPECTION AFTER DISASSEMBLY
Joint Cover
Check joint cover protrusion for damage. Replace if there are.
Rack and Pinion Assembly
• Check pinion assembly for damage or wear. Replace as necessary.
• Rotate pinion assembly and check for torque variation or rattle. Replace steering gear as necessary.
Gear Housing Assembly
Check gear housing assembly for damage or scra tches. Replace steering gear as necessary.
Outer Socket and Inner Socket
1. Check ball joint swinging torque.
• Hook Tool at the point shown and pull the spring balance.
Make sure that the spring balance reads the specified value
when ball stud and inner socket start to move. Replace outer
socket and inner socket if they are outside the standard.
2. Ball joint axial end play • Apply an axial load of 490 N (50 kg-f, 111 lb-f) to ball stud.
Measure amount of stud movement using a dial gauge, and
then make sure that the value is within the specified range.
Replace outer socket and inner socket if the measured value
is outside the standard.
ASSEMBLY
1. Apply recommended grease to teeth part and bush part of rack assembly, if necessary.
2. Apply recommended grease to back of rack assembly, if necessary.

3. Install inner socket to rack assembly. Torque to specified value while holding the flat portion of the racknext to the inner socket using a suitable tool.
4. Apply recommended grease to inner socket.
5. Decide on the neutral position for the rack assembly.
6. Apply recommended grease to around retainer (3), then install retainer (3), spring (4) and adjusting screw (1) to gear housing
assembly (5).
7. Apply recommended thread locking sealant to the thread (2 turns thread), and then screw in the adjusting screw (1) until it
reaches height “H” from gear housing assembly (5) measured
before disassembling.
8. Tighten lock nut to (2) the specified torque securing it to prevent adjusting screw (1) from freewheeling condition.
9. Move rack assembly 10 strokes throughout the full stroke so that the parts can fit with each other.
10. Using Tools A and B, measure rotating torque of pinion assem- bly. If the measurement is out side of the specified range, read-
just pinion rotating torque. If the measurement is outside of the
specified range for readjust, replace steering gear assembly.
11. Set dial gauge to the back of rack assembly on the pinion assembly side around the center of stroke. Measure displace-
ment of rack under torsional torque of ± 7.8 N·m (0.80 kg-m, 69
in-lb), and then check if it is within the standard value. If the
measurement is outside the standard value, adjust it again. After
the readjustment, if measurement is still outside the standard
value, replace steering gear assembly.
12. Install boot to gear housing assembly and inner socket. Rack stroke “L” : Refer to
PS-21, "
