STEERING WHEEL

2. Place front wheels on turning radius gauges and rear wheels on

stands, so that vehicle can be level.

3. Check the maximum inner and outer wheel turning angles for

(RH/LH) road wheels.

• With the engine at idle, turn steering wheel from full left stop to

full right stop and measure the turning angles.

• Check the following items when turning angle is out of the standard.

- Check rack stroke (L).

- If rack stroke is out of specification, replace steering gear

assembly.

• Steering angles are not adjustable. Check steering gear

assembly, steering column assembly, and front suspension

components for wear or damage if any of the turning angles

are different from the specified value. Replace any of them, if

any non-standard condition exists.

STEERING COLUMN ASSEMBLY

• Check each part of steering column assembly for damage or other malfunctions. Replace entire steering col-

umn assembly if any parts are damaged.

• Measure steering column rotating torque using Tool. Replace

steering column assembly if outside the specification.

• Measure the length (L) as shown if vehicle has been involved in a

minor collision. Replace steering column assembly if outside the

specifications.

• Check each part of steering column assembly for damage or other malfunctions. Replace if there are any

abnormal conditions.

• Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel

turning angle.Refer to

ST-5, "Inspection"

• Check tilt mechanism operating range and telescopic mechanism

operating range as shown.

INSPECTION AFTER DISASSEMBLY

BOOT

• Check boot for cracks. Replace if any damage is found.

STEERING GEAR ASSEMBLY HOUSING

• Check steering gear assembly housing for damage and scratches. Replace if there are any abnormal condi-

tions.

OUTER SOCKET AND INNER SOCKET

• Ball joint swinging torque

- Hook a spring balance to the ball stud and inner socket measuring

point (*) and pull the spring balance. Make sure that the spring bal-

ance reads the specified value when ball stud and inner socket

start to move. Replace outer socket and inner socket if they are

outside the specification.

• Ball joint rotating torque

- Make sure that the reading is within the following specified range

using Tool. Replace outer socket if the reading is outside the spec-

ification.

• Ball joint axial end play

- Apply an axial load of 490 N (50 kg, 110 lb.) to ball stud. Measuring

the amount of stud movement using a suitable tool, make sure that

the value is within specification. Replace outer socket (A) and

inner socket (B) if the measured value is outside specification.

INSPECTION AFTER INSTALLATION

• Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.

• Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel

turning angle.

- Steering wheel play: Refer to

ST-5, "Inspection"

.

- Neutral position steering wheel, steering wheel turning force, and front wheel turning angle: Refer to

ST-5,

"Inspection"

.
