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
