ers, caulk it so that the clearance of caulking por-
tion becomes 2mm (0. 079 in) or less.
32) Fix the boot end with small clip.
33) After installing, check that the boot end is in-
stalled to the groove of the tie–rod.

35) Inspect the gearbox as follows:
Holding the “A” tie–rod end, repeat movement from
lock to lock two or three times as quickly as possi-
ble.
Holding the “B” tie–rod end, turn a few times as
slowly as possible.
Finally, make sure that the boot is installed in the
specified position without inflating.
36) Remove the gearbox from ST.

1) Lift-up the vehicle.
2) If a fluid leak is found, clean the fluid completely
from the suspect area, and turn the steering wheel
approx. 30 to 40 times to the left and right from lock
to lock, with the engine running, and check again
for leaks immediately, and also after a few hours
have passed.
3) Cause and solution for oil leakage from “a”
The oil seal is damaged. Replace the valve assem-
bly with a new one.
4) Cause and solution for oil leakage from “b”.
The torsion bar O–ring is damaged. Replace the
valve assembly with a new one.
5) Cause and solution for oil leakage from “c”.
The oil seal is damaged. Replace the valve assem-
bly or oil seal with a new one.
6) Cause and solution for oil leakage from “d”.
The pipe is damaged. Replace the faulty pipe or O-
ring.
7) Cause and solution for oil leakage from “g”.
The hose is damaged. Replace the hose with a
new one.
8) If leak is other than a, b, c, d or g, or if oil is leak-
ing from gearbox, move the right and left boots to-
ward tie-rod end side, respectively, with the
gearbox mounted to the vehicle, and remove fluid
from surrounding portions. Then, turn the steering
wheel from lock to lock about thirty to forty times
with the engine running, and make comparison of
the leaked portion immediately after and several
hours after this operation.
(1) Leakage from “e”
The cylinder seal is damaged. Replace the rack
bushing with a new one.
(2) Leakage from “f”
There are two possible causes. Perform the fol-
lowing step first. Remove the pipe assembly B
from the valve housing, and close the circuit us-
ing ST.
ST 926420000 PLUG
Turn the steering wheel from lock to lock ap-
prox. 30 to 40 times with the engine running,
then inspect the leaked portion immediately af-
ter and several hours after this operation.
•If leakage from “f” is noted again:
The oil seal of pinion & valve assembly is dam-
aged. Replace the pinion & valve assembly with a
new one. Or replace the oil seal and the parts that
are damaged during disassembly with new ones.
•If oil stops leaking from “f”:
The oil seal of rack housing is damaged. Replace
the oil seal and parts that are damaged during dis-
assembly with new ones.
F: ADJUSTMENT
1) Adjust the front toe.
SPECTION, Wheel Alignment.>
Standard of front toe:
IN 3 — OUT 3 mm (IN 0.12 — OUT 0.12 in)
2) Adjust the steering angle of the wheels.
Specification of steering angle:
3) If the steering wheel spokes are not horizontal
when wheels are set in the straight ahead position,
or error is more than 5° on the periphery of the
steering wheel, correctly re-install the steering
wheel.
4) If the steering wheel spokes are not horizontal
with vehicle set in the straight ahead position after
this adjustment, correct it by turning the right and
left tie–rods in the opposite direction from each oth-
er by the same angle.
