STEERING GEAR TOTAL PINION TORQUE 
CHECK

Required Special Tool:

• MB991006: Preload Socket

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.

• Do not loosen the adjust screw more than 2 rotations.
• If the adjust screw is loosened more than 2 rotations, or 

if it is removed, replace the steering gear assembly.

1. Using special tool 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 

− 1.9 N⋅m (7.1 − 16.8 in-lb)

[Change in torque: 0.7 N

⋅m (6.2 in-lb) 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 the total pinion torque or the change in torque is outside 

the standard value, loosen the rack support cover once and 
retighten it to the specified torque 12 

± 2 N⋅m (107 ± 17 

in-lb). And then loosen the rack support cover 10 degrees, 
and check the pinion torque again.
If the total pinion torque cannot be adjusted to within the 
standard range by adjusting the rack support cover, replace 
the power steering gear.

.

TIE ROD SWING RESISTANCE CHECK

1. Give 10 hard swings to the tie rod.
2. Measure the tie rod swing resistance with a spring scale.

Standard value:

3.7 

− 18.1 N (0.83 − 4.07 lb) <vehicles with 16-inch 

wheels>

3.6 

− 17.8 N (0.81 − 4.00 lb) <vehicles with 17-inch 

wheels>

[Swing torque: 1.0 

− 4.9 N⋅m (8.9 − 43.3 in-lb)]

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.37-38

).
