Precautions for Steering DiagnosisS6RW0D6100001
Since the problems in steering involve several systems, they must all be considered when diagnosing a complaint. To
avoid using the wrong symptom, always road test the vehicle first. Proceed with the following preliminary inspection
and correct any defects which are found.
1) Inspect tires for proper pressure and uneven wear.
2) Raise vehicle on a hoist and inspect steering system for loose or damaged parts.
3) Spin front wheels. Inspect for out-of-round tires, out-of-balance tires, bent rims, loosen and/or rough wheel
bearings.

Steering Wheel Play CheckS6RW0D6304021
• Check steering wheel for looseness or rattle by
moving it in its shaft direction and lateral direction.
If found defective, repair or replace.
• Check steering wheel for play, holding vehicle in
straight forward condition on the ground with engine
stopped.
If steering wheel play is not within specification,
inspect as follows and replace if found defective.
– Tie-rod end ball stud for wear (Ball stud should
move when more than 0.2 N⋅m (2 kg-cm, 0.44 lb-ft)
torque is applied.)
– Lower ball joint for wear
– Steering shaft joint for wear
– Steering pinion or rack gear for wear or breakage
– Each part for looseness
Steering wheel play
“a”
: 0 – 30 mm (0 – 1.18 in.)
Steering Force CheckS6RW0D6304022
1) Place vehicle on level road and set steering wheel at
straight-ahead position.
2) Check if tire inflation pressure is as specified
referring to the tire placard.
3) Remove driver air bag (inflator) module referring to
“Driver Air Bag (Inflator) Module Removal and
Installation in Section 8B”.
4) Start engine.
5) With engine idling, measure steering force by turning
torque wrench.
Steering force
: Less than 6.4 N⋅m (0.64 kgf-m, 4.6 lb-ft)
6) Install driver air bag (inflator) module referring to
“Driver Air Bag (Inflator) Module Removal and
Installation in Section 8B”.

3) Inspect for proper toe referring to “Front Wheel
Alignment Inspection and Adjustment in Section 2B”.
4) After confirming proper toe, tighten tie-rod end lock
nut to specified torque.
Tightening torque
Tie-rod end lock nut (a): 45 N·m (4.5 kgf-m, 32.5
lb-ft)
5) Tighten wheel bolts to specified torque and lower
hoist.
Tightening torque
Wheel bolt: 85 N·m (8.5 kgf-m, 61.5 lb-ft)
Tie-Rod End InspectionS6RW0D6306004
• Inspect for play in ball joint.
• Inspect for play in rack end ball joint.
In either case, if found defective, replace.
Steering Shaft Joint On-Vehicle InspectionS6RW0D6306005
Check shaft joint for wear, breakage and any other
damage and replace if any defect exists.

Removal
CAUTION!
Be sure to set front wheels (tires) in straight
direction and remove ignition key from key
cylinder before performing the following
steps, otherwise, contact coil of air bag
system may get damaged.

1) Remove steering joint cover.
2) Make alignment marks (1) on pinion shaft (2) and
joint of steering lower shaft (3) for a guide during
reinstallation.
3) Loosen joint bolt (steering column side) (4) and
remove joint bolt (pinion shaft side) (5) and
disconnect steering lower shaft (3) from pinion shaft
(2).
4) Disconnect torque sensor connector and P/S motor
connector from steering gear case.
5) Remove front suspension frame referring to “Front
Suspension Frame, Stabilizer Bar and/or Bushing
Removal and Installation in Section 2B”, and then
