1. DESCRIPTION
The vehicles covered by this manual are equipped
with either a TRW power steering system or a
Japanese PR24SA power steering system.

Both types are similar in construction and appear-
ance.

The power steering is a rack and pinion type
which is mounted on the lower section of the engine
compartment bulkhead by rubber mountings and
brackets.

Hydraulic pressure is supplied to the power
steering gear by a pump driven by a drive belt from
the engine.

The power steering pump has a separate fluid
reservoir located on the righ t side of the bulkhead.

No lubrication of the steering gear or steering
pump is required in service and in the event of the
loss of power assistance, the steering will continue to
operate but will require a greatly increased effort.
However, as the steering gear and pump are lubricated
by the power steering fluid, the cause of the loss of
power steering or fluid loss must be determined and
repaired promptly to prevent damage to the steering
pump and to a lesser extent, the steering gear.

The t i e rod ends and rubb er boots can be renewed
without removing the steering gear from the vehicle.
To renew the integral t i e rod and tie rod ball housings,
the steering gear must be removed.

As specialist knowledge and equipment are re-
quired to overhaul the power steering gear and the

hydraulic pump, it is recommended that these op-
erations be carried out by an authorized dealer.
However, procedures for the removal and installa-
tion of the steering gear and pump are fully de-
scribed in this section.

The steering column is of the energy absorbing
type and is designed to collapse in the event of a
severe front end collision. The energy absorbing com-
ponents are the column tu bes, steering shaft and tilt
bracket breakaway capsules. All these components
should be handled with extr eme care if service opera-
tions are to be carried out on the steering column
assembly.

2. IN CAR ADJUSTMENTS, CHECKS AND
MINOR REPAIRS

If the power steering system becomes partially or
fully inoperative it is most important that the follow-
ing preliminary inspection and testing procedure be
performed prior to undertaking any trouble shooting
or repair operations.

PUMP DRIVE BELT
Inspect the pump drive belt for breakage, glazing
or wear. If any of these characteristics are evident,
renew the belt using only a genuine replacement.

If the belt is loose but still serviceable, adjust it
using the procedure outlined in the Engine Tune-up
section.

NOTE: In most cases a loose drive belt can
be heard squealing when a load is placed on
the pump as the steering wheel is turned or
as the engine speed is increased.

Checking the power steering pump drive belt for
deterioration.

154 Steering —
(2) Remove the air inlet duct from the air
cleaner and throttle body. (3) Position a container or a piece of cloth
beneath the steering pump reservoir and disconnect
the fluid return and power steering pump supply hose
from the reservoir.
(4) Loosen the steering pump drive belt as
described in the Engi ne Tune-up section.
(5) Loosen the return hose clamp and the supply
union and disconnect the hoses from the power
steering pump. Plug the hoses to prevent the loss of
fluid.
(6) Loosen the retaining bolts and withdraw the
pump. (7) Thoroughly clean the exterior of the steering
pump and inspect it for cracks, damage and signs of
leakage.
Installation is a reversal of the removal procedure
with attention to the following points:

(1) Install the pump and retaining bolts.
(2) Install the drive belt and adjust it as de-
scribed in the Engine Tune-up section. (3) Install the hoses to the power steering pump
and tighten securely. (4) Top up the pump reservoir and purge the
power steering system of air as previously described.
TO OVERHAUL

As specialist knowledge and equipment arc re-
quired to overhaul the power steering pump, it is
recommended that this operation be performed by an
authorized dealer or steering specialist.

6. POWER STEERING GEAR ASSEMBLY
Special Equipment Required:
To Renew Tie Rod Ball Housings — Large Still-
sons
TO REMOVE AND INSTAL
The procedures for removing and installing the
power steering gear are similar to those carried out in
the Manual Steering section under the Steering Gear
Assembly heading except fo r the following differences.

(1) Place a container under the pressure and
return pipes that are conn ected to the steering gear
valve housing. Remove the pipes and allow the fluid
to drain into the container. (2) Suitably seal the pipes and the steering gear
to prevent the entry of di rt whilst the pipes are
removed.
(3) Upon removal of the power steering gear,
thoroughly clean the steering gear except the tie rod
ends in a suitable solvent. Be careful not to allow the
solvent to enter the apertu res where the pressure and
return pipes were removed. (4) Check the pipes and co nnections for cracks,
damage or obstructions and renew as necessary.

Installed view of the power steering gear with the
engine removed.
Installation is a reversal of the removal procedure
with attention to the following points:

(1) Install the pressure and return pipes to the
steering gear valve housing and tighten securely. (2) Fill the power steering reservoir to the cor-
rect level and bleed the system as described previously
under the heading In Car Adjustments. Checks and
Minor Repairs. (3) Check all power steering pipe connections
for leaks and repair as necessary. (4) Check, and if necessary, adjust the front
wheel toe in as described in the Front Suspension
section. After adjustment ensure that the rubber boots
are not distorted or twisted and the rubber boot
clamps and clips are facing downward.
TO OVERHAUL

As specialist knowledge and equipment are re-
quired to overhaul the power steering gear, it is rec-
ommended that this opera tion be performed by an
authorized dealer or steering specialist.

TO RENEW TIE ROD BALL HOUSINGS
TRW Steering Gear
The renewal of the tie rod ball housings is the
same as for the manual steering gear. Refer to Part 2.
Manual Steering section.

PR24SA Steering Gear
(1) Remove the power steering gear assembly
from the vehicle as previously described.
(2) Carefully mount the power steering gear in a
vice equipped with soft jaws. Loosen the tie rod end
locknuts without disturbing the location of the tie rod
ends and unscrew the tie rod ends, taking note of the
number of turns required to remove them. Unscrew
and remove the locknuts from the tie rod. (3) Remove the clamps from the rubber boots
and remove the boots.

Front Suspension 163
(2) Ensure that the stabilizer bar links are in
good condition. Renew if necessary.
(3) When installing the stabilizer bar ensure that
the links are installed perpendicular to the control arm
with the ball joint socket face parallel to the end of the
stabilizer bar. (4) Ensure that the brackets are installed with
the flat portion facing towards the front of the vehicle.
Tighten the retaining bolts securely.
7. SUSPENSION AND STEERING ANGLES

ADJUSTMENT
NOTE: Extensive knowledge and special-
ised equipment are required to measure and
correct the suspension and steering angles
with the exception of the front wheel toe in.
Therefore, as it is not a viable proposition
for the average person to carry out a com-
plete wheel alignment, the vehicle should be
taken to a wheel alignment specialist.

Prior to carrying out a wheel alignment, a thor-
ough inspection of the steering linkage, front hub
bearings, ball joints and suspension units should be
carried out. Faulty components should be renewed or
repaired as necessary.

The tread of the front ti res should be examined
for excessive or uneven wear as certain conditions of
tire wear are indicative of damaged or worn compo-
nents in the suspension, stee ring linkage and/or wheels
and bearings. Refer to the heading Tire Wear Trouble
Shooting in the Wheels and Tires section. If the tires
are found to be defective, renew them with serviceable
lyres.

TO CHECK AND ADJUST TOE IN/OUT
NOTE: The vehicle s hould be unladen ex-
cept for the normal amount of fuel and with
the tires inflated to the correct pressures.

(1) With the vehicle on a level floor, raise the
front of the vehicle and s upport it on chassis stands.
(2) Spin each front wheel in turn and using a
piece of chalk, mark a line around the periphery of
each tire as near to the centre as possible. (3) Lower the vehicle to the ground and bounce
the front several times to stabilize the suspension. (4) Set the wheels in the straight ahead position.
(5) Mark the centre chalk line on both tires at a
point approximately 200 mm above the floor and
forward of the suspension. (6) Using a tape measure, measure and record
the distance between the two marked points on the
tire centers.

Diagram indicating the front wheel toe in. Refer to
Specifications for the correct difference between
measurement A and B.
(7) Maintaining the wheels in the straight ahead
position, roll the vehicle forward until the marks are
the same distance from the floor but to the rear of the
suspension. (8) Again using the tape measure, measure and
record the distance between the marks on the tires.
(9) The difference between the front and rear
measurement will give the correct toe in/out reading.
If the larger measurement is at the front, the wheels
are in a toe out position. If the reverse is true, the
wheels are in toe in position. Compare the reading
obtained with the figure given in Specifications.
(10) If adjustment of the to e in/out is necessary,
loosen the tie rod locknuts on both sides. (11) Remove the retaining clips from the small
end of the steering rack rubber boots. (12) Turn the tie rods as required until the correct
toe in/out reading is obtained.
NOTE: It is important to turn each tie rod
equally to maintain the central position of
the steering gear. Ensure that the lengths of
the tie rods are the same.

(13) Tighten the tie rod locknuts to the specified
torque without changing the positions of the adjusters.
(14) Install the retaining clips to the small end
of
the steering rack rubber boots, ensuring that the boots
are not twisted.
