NOTE: This repair is only necessary if one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to free the valves in
the valve bodies.
1. Soak a sheet of # 600 abrasive DaDer in ATF for
about 30 minutes.
2. Caretully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may be necessary to use a small
scrawdriv6r to pry the the valve f.66. Bs caloful not
to sciatch th€ bole with th6 scrowdriver.
Remove the #600 paper and tho.oughly wash the
entire valve body in solvent, th€n dry with com-
pressed air.
Coat the valve with ATF then droD it into its bore.
It should droD to the bottom of the bore under its
own weight. lf not, repeat step 4 then retest.
lf the valve still sticks, replace the valve body.
InsDect the valve for anv scuff marks. Use the ATF-
soaked # 600 paper to polish ofl any burrs that are
on the valve. then wash the valve in solvent and drV
it with compressed air,
Roll up halt a sheet ot ATF-soaked paper, and insert
it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits
the bore tightly. then polish the bore by twisting thepaper as you push it in and out.
CAUTION: The valvs body is aluminum and doesn't
require much polishing ro lomovo any bulla.
VALVE BODY
7.Remove the valve. and thoroughly clean it and the
valve body with solvent. Dry all parts with com-pressed air, then reassemble using ATF as alubricant.

Drivcshatt Boot
Check the boots on the driveshaft tor cracks. damage,
leaking grease or loose boot bands.
lf any damage is found, replace the boot and boot
oanos.
Looso SplineE
Turn the driveshaft by hand and moke sure the splines
and joint are not excessively loose.
lf damage is found, replace the joints if necessary.
Twisled or Crscked
Make sure the driveshaft is not tlvisted or cracked.
Replace it if necessary.

1.Loosen the wheel nuts slightly,
Raise the front of ca. and support it with safety
stands in the prope. locations {see section 1).
Remove the wheel nuts and front wheels.
5.
Drain the transmission oil or fluid (see section 13 or
14t.
NOTE: lt is not necessary to drain the transmission
oil or fluid when the left driveshaft is removed.
Raise the locking tab on the spindle nut, then
remove the nut.

INPUT SHAFT
High assist at lower speedsl
When steering resistance is high, such as when driving at low speed, or when turning the wheel with the car stopped, the
diiference in angle created between the input shaft and the valve opens the tluid passage on one side, and closes the fluidpassage on the other side, at each pair of orifices. The fluid pressure lncreases in the side of the power cylinder fed by thelarger fluid passage. This increased pressure pushes on the rack piston, allowing the steering wheel to be turned with light
effon. On the other side of the power cylinder, the return passage opens allowing the steering fluid to return through theinput shaft to the reservoir. The fluid passages to the power cylinder automatically change in size, increasing as the steer-ing resistance increases. In other words, the passages become larger and power assist increases when the steering effort
would normally be high, (for example, when parking or making low speed turns), and the passages become smaller andpower assist decreases when the steering effort would normally be low, (for example, when driving at high speeds or
straight ahead).

Pressure Control
Low assist at higher speedsl
When steering resistance is low, such as when driving at high speeds, or when driving straight ahead. the lnput shaft is
near or in the neutral position, so there is liftle or no flow to any of the power cylinder orifices. Most of the feed pressure
from the pump is bypassed to the reservoir. Because of this, the pressure stays the same in both sides of the power cvlin-
der, resulting in low or no assist.

NOTE: lf an intact airbag assembly has been removed
from a scrapped car or has been found defective or
damaged during transit, storage or service, it should be
deDloyed (see section 23).
