INSPECTION

M1372011000367

STEERING GEAR TOTAL PINION
TORQUE CHECK

CAUTION

When holding the steering gear in a vice, secure
its mounting positions. If it is secured in any
other place, the gear housing may become
deformed or damaged.

AC208337AB

MB991006

1. Using special tool preload socket (MB991006),

rotate the pinion gear at the rate of one rotation in
approximately 4 to 6 seconds to check the total
pinion torque.

Standard value:

TOTAL PINION TORQUE: 1.29

− 2.23 N⋅m

Change in torque: 0.92 N

⋅m or less

NOTE: When measuring, remove the bellows
from the rack housing. Measure the pinion torque
through the whole stroke of the rack.

2. If not within the specification, replace the steering

gear and linkage assembly (Refer to

P.37-96

).

TIE ROD SWING RESISTANCE CHECK

1. Give 10 hard swings to the tie rod.

AC000997

2. Measure the tie rod swing resistance [tie rod

swing torque] with a spring balance.

Standard value: 6

− 19 N [1.5 − 4.9 N⋅m]

3. If the measured value exceeds the standard

value, replace the tie rod.

4. If the measured value is below the standard value,

the tie rod can be re-used if it swings smoothly
without excessive play.

TIE ROD END BALL JOINT DUST COVER
CHECK

1. Check the dust cover for cracks or damage by

pushing it with your finger.

2. If the dust cover is cracked or damaged, replace

the tie rod end (Refer to

P.37-96

).

NOTE: Cracks or damage of the dust cover may
damage the ball joint. If it is damaged during serv-
ice work, replace the dust cover (Refer to

P.37-96

).
