REMOVAL SERVICE POINTS
ATIE-ROD END AND KNUCKLE DISCONNECTION
Caution
1. In order not to damage the ball joint thread, the tie
rod end mounting nut must be only loosened but not
removed from the ball joint. Be sure to use the special
tool.
2. Tie the special tool with a cord so as not to fall off.
BGEAR BOX ASSEMBLY REMOVAL
Caution
Do not damage the bellows and the tie-rod end dust cover
when removing the gear box assembly.
INSPECTION

Check the rubber parts for cracks and breakage.
GEAR BOX TOTAL PINION TORQUE
Using the special tools, rotate the pinion gear at the rate
of one rotation in approximately 4 to 6 seconds to check
the total pinion torque.
Standard value: 0.9 – 1.7 Nm
[Change in torque: 0.4 Nm]
Caution
When holding the steering gear box assembly in a vice,
secure its mounting positions. If it is secured in any other
places, the gear housing may become deformed or
damaged.
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
starting torque again.

If the total pinion starting 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.
CHECK THE TIE ROD FOR SWING RESISTANCE
1. Give 10 hard swings to the tie rod.
2. Measure the tie rod swing resistance with a spring balance.
Standard value: 5–18 N [1.5–4.9 Nm]
3. If the measured value exceeds the standard value, replace
tie rod.
4. Even if the measured value is below the standard value,
the tie rod which swings smoothly without excessive play
may be used.

2. Apply a coating of the specified fluid to the outside of
the ball bearing. Using the special tools, press the ball
bearing into the valve housing.
Specified fluid:
Automatic transmission fluid
DEXRON or DEXRON II
HSEAL RING INSTALLATION
1. Kneed the seal ring to soften it.
2. Apply the specified fluid to the seal ring, and install to
the rack groove.
Specified fluid:
Automatic transmission fluid
DEXRON or DEXRON II
3. Insert the tapered side of the special tool from the pinion
gear side, and compress the seal ring.
IOIL SEAL INSTALLATION
Use the special tool to press the oil seal into the valve housing.
The upper surface of the oil seal should project outwards
approx. 1 mm from the housing edge surface.
Caution
If the oil seal is flush with or lower than the housing
edge, it will cause oil leaks and require reassembly.
JEND PLUG INSTALLATION
1. Apply the specified sealant to the threaded part of the
end plug.
Specified sealant:
3M ATD Part No.8661 or equivalent
2. Secure the threaded portion of the end plug at two places
by using a punch.
KTOTAL PINION TORQUE ADJUSTMENT
1. Position the rack at its centre. Tighten the rack support
cover to 15 Nm.
2. In neutral position, rotate the pinion shaft clockwise one
turn/4 – 6 seconds with the special tool. Return the rack
support cover 30 – 60 and adjust torque to the standard
value.

3. Using the special tools, rotate the pinion gear at the rate
of one rotation in approximately 4 to 6 seconds to check
the total pinion torque.
Standard value: 0.9 – 1.7 Nm
[Change in torque: 0.4 Nm]
Caution
(1) When adjusting, set the standard value at its
highest value.
(2) Assure no ratcheting or catching when operating
the rack towards the shaft direction.
NOTE
When it cannot be adjusted within the specified return
angle, check or replace the rack support cover
components.
4. After adjusting, lock the rack support cover with lock nut.
LTAB WASHER / TIE-ROD INSTALLATION
After installing the tie-rod to the rack, fold the tab washer
end (2 locations) to the tie-rod notch.
MBELLOWS BAND INSTALLATION
1. Turn the adjusting bolt of the special tool to adjust the
opening dimension (W) to the standard value.
Standard value (W): 2.9 mm

Screw in the adjusting bolt.

Loosen the adjusting bolt.
NOTE
(1) The dimension (W) is adjusted by approx. 0.7 mm
per one turn.
(2) Do not turn the adjusting bolt more than one turn.
