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.

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: 0.8 

− 2.1 N⋅m

[Change in torque: 0.6 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.
If the measured value is not within the standard 
range, first adjust the rack support cover, and then 
check the total pinion torque again.
If the total pinion torque cannot be adjusted to within 
the standard range by adjusting the rack support 
cover, check the rack support cover, rack support 
spring, rack support and replace any parts if 
necessary.

TIE ROD SWING RESISTANCE CHECK

1. Give 10 hard swings to the tie rod.

2. Measure the tie rod swing resistance [tie rod 

swing torque] with a spring balance.

− 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.

the tie rod end (Refer to 

P.37-24

).

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