in.).
(c) Using a brass bar and a hammer, stake the washer.
NOTICE:
Avoid any impact to the rack.
16. INSTALL RH AND LH RACK BOOTS, CLAMPS AND
CLIPS
(a) Make sure that the steering rack hole is not clogged with
grease.
HINT:
If the hole is clogged, the pressure inside the boot will change
after it is assembled and the steering wheel turned.
(b) Install the boot.
NOTICE:
Be careful not to damage or twist the boot.
(c) Install the clamp and clip to the boot.
HINT:
When the rack guide spring cap is toward you, install the clip
and clamp in the positions shown in the illustration.
17. INSTALL RH AND LH TIE ROD ENDS AND LOCK NUTS
(a) Screw the lock nut and tie rod end onto the rack end until
the matchmarks are aligned.
(b) After adjusting toe-in, torque the nut (See page
SA-2).

(a) Install the union seat.
(b) Using SST, install the tube.
SST 09633-00020
Torque: 24 N´m (243 kgf´cm, 18 ft´lbf)
HINT:

Use a torque wrench with a fulcrum length of 300 mm
(11.81 in.).

This torque value is effective in case that SST is parallel
to a torque wrench.
(c) Torque the union bolt over 2 new gaskets.
Torque: 34 N´m (350 kgf´cm, 25 ft´lbf)

(c) Turn the left and right rack ends an equal amount to adjust
the toe-in.
HINT:

Make sure that the lengths of the left and right rack ends
are the same.

Try to adjust the toe-in to the center value.
Rack end length difference:
1.5 mm (0.059 in.) or less
(d) Tighten the tie rod end lock nut.
Torque: 56 N´m (570 kgf´cm, 41 ft´lbf)
(e) Place the boot on the seat and clip it.
HINT:
Make sure that the boots are not twisted.
7. INSPECT WHEEL ANGLE
Turn the steering wheel fully and measure the turning angle.

(30.75°)30°35'
(30.58°)
If the wheel angle are not within the specifications, check to see
if the lengths of the left and right rack ends are the same.
HINT:
If the tie rods lengths are not equal, the wheel angle cannot be
adjusted properly. Reinspect the toe-in after adjusting the tie
rods lengths.

5. ADJUST CAMBER AND TOE-IN
(a) Measure the length of the lower suspension arm No.1 and
No.2, as shown in the illustration.
Length:
(E - F) or (F - E) should be less than 4.0 mm (0.16 in.).
If not, adjust the length of the arms by turning the adjusting cam
as shown, until (E - F) or (F - E) is less than 4.0 mm (0.16 in.).
(b) Measure the camber and toe-in.
If the camber and toe-in are still not within the specification, ad-
just the camber and toe-in with the adjusting cam.
(c) Remove the bolt and disconnect the parking brake cable
bracket.
