>>H<< TOTAL PINION TORQUE
ADJUSTMENT

CAUTION

• Be sure there is no ratcheting or catching

when operating the rack towards the shaft.

• Measure the total pinion torque through the

whole stroke of the rack.

1. Using special tool preload socket (MB991006),

rotate the pinion shaft at the rate of one rotation in
4 to 6 seconds to check the total pinion torque and
the change in torque.

Standard value:

Total pinion torque: 0.8

− 2.1 N⋅m [Change in

torque: 0.6 N

⋅m or less]

CAUTION

When adjusting, set at the highest value of the
standard value range.

NOTE: If the total pinion toque cannot be adjusted
to the standard value within the specified return
angle, check the rack support cover components
and replace any parts if necessary.

2. If the total pinion torque or the change in torque is

outside the standard value, move the rack support
cover 0

− 30°, and adjust the pinion torque again.

>>I<< TAB WASHER/TIE ROD
INSTALLATION

After installing the tie rod to the rack, fold tab washer
end (two locations) to tie rod notch.

>>J<< BELLOWS BAND INSTALLATION

1. Turn the adjusting bolt of special tool boot band

crimping tool (MB991561) to adjust the opening
dimension (W) to the standard value.
NOTE: The dimension (W) is adjusted by
approximately 0.7 mm per one turn.
NOTE: Do not turn the adjusting bolt more than
one turn.

Standard value (W): 2.9 mm
<When more than 2.9 mm>: Screw in the
adjusting bolt.
<When less than 2.9 mm>: Loosen the
adjusting bolt.

CAUTION

• Hold the rack housing, and use special tool to

crimp the bellows band securely.

• Crimp the bellows band until special tool

touches the stopper.

2. Use special tool boot band crimping tool

(MB991561) to crimp the bellows band.

3. Check that crimped width (A) is within the

standard value.

Standard value (A): 2.4

− 2.8 mm

<When more than 2.8 mm>: Readjust the
dimension (W) of step (1) to the value
calculated by the following equation, and
repeat step (2).
W = 5.5 mm

− A [Example: if (A) is 2.9 mm,

(W) is 2.6 mm.]
<When less than 2.4 mm>: Remove the
bellows band, readjust the dimension (W) of
step (1) to the value calculated by the
following equation, and use a new bellows
band to repeat steps (2) to (3).
W = 5.5 mm

− A [Example: if (A) is 2.3 mm,

(W) is 3.2 mm.]

>>K<< TIE ROD END/LOCK NUT
INSTALLATION

Screw in the tie rod end to achieve the right and left
length as illustrated. Lock with the lock nut.
NOTE: The lock nuts must be tightened securely
only after the steering gear is installed to the vehicle
and toe-in is adjusted.

TIE ROD END BALL JOINT DUST COVER
REPLACEMENT

M1372008200402

If the dust cover is damaged accidentally during
service work, replace the dust cover as follows:

1. Apply specified grease to the lip and inside of the

dust cover.

Specified grease:
Multipurpose grease SAE J310, NLGI No.2 or
equivalent

2. Drive in the dust cover with special tool front axle

base (MB990776) until it is fully seated.

3. Check the dust cover for cracks or damage by

pushing it with your finger.
