2. If the total rotation torque or torque fluctuation does not
meet the standard values, adjust by returning the rack
support cover within a range of 0 to 30_.
Caution
(1) Adjust around the maximum limit of the standard
values.
(2) See that no ratcheting or catching are present
when operating the rack towards the shaft
direction.
(3) Measure the total pinion torque through the whole
stroke of the rack.
3. If the adjustment is impossible in the given range, check
the components of the rack support cover, and replace
if necessary.
"LATAB WASHER/TIE ROD INSTALLATION
After installing the tie rod to the rack, fold the tab washer
end (2 locations) to the tie rod notch.
"MABELLOWS 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 about 0.7 mm per
one turn.
(2) Do not turn the adjusting bolt more than one turn.
2. Use the special tool to crimp the bellows band.
Caution
(1) Hold the rack housing, and use the special tool
to crimp the bellows band securely.
(2) Crimp the bellows band until the special tool
touches the stopper.

3. See that the crimped width (A) meets the standard value.
Standard value (A): 2.4-2.8 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.]

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.]
"NATIE ROD END/LOCKING NUT INSTALLATION
Screw in the tie rod end until the dimension shown is achieved.
Then, temporarily tighten with the locking nut.
NOTE
The locking nut must be tightened securely only after the
power steering gear box and linkage are installed to the vehicle
and toe-in is adjusted.
"OAGEAR MOUNTING RUBBER INSTALLATION
Install the gear mounting rubber to the rack housing so that
the distance is as shown in the illustration.
TIE ROD END BALL JOINT DUST COVER
REPLACEMENT
Only when the dust cover is damaged accidentally during
service work, replace the dust cover as follows:
1. Apply grease to the inside of the dust cover.
