.

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

).
