Front Suspension 157


Check the stabilizer bar links for wear and damage.
(3) Incorrect front end alignment: Check and
adjust the alignment as necessary. (4) Defective stabilizer bar mounting rubbers or
worn link ball joints: Renew component as necessary. (5) Weak or broken front coil spring: Renew
both springs as a matching pair. (6) Broken or weak rear coil spring: Renew both
springs as matching pair. (7) Drive shaft bent or distorted: Check and
renew as necessary. (8) Tie rod end worn or damaged: Check and
renew as necessary.
(9) Control arm ball joint worn or damaged:
Check and renew as necessary.
(10) Control arm mounting bolts loose: Tighten
the control arm bolts. (11) Wheel hub bearing worn: Check and renew
as necessary. NOTE: As a quick guide to suspension unit
condition, bounce the front of the vehicle up
and down (one side at a time), the vehicle
should come to rest in a single movement. If
it bounces two or three times before stop-
ping, the suspension unit should be renewed.
If the from of the vehicle is tower on one
side than the other, remove the coil spring
and check its free length against a new
spring. If the spring is found to be unservice-
able it is good practice to install two new
springs as a matching pair. This also applies
to the springs on the rear of the vehicle.

2. DESCRIPTION
The front suspension is an independent type
comprising two Macpherson strut suspension units
mounted vertically on each side of the vehicle. The
lower end of the suspension unit is bolted to the
steering knuckle, which in turn houses the front hub
bearings. The steering knuckle pivots on the control
arm by means of a ball joint.

The control arm pivots at its inner ends on rubber
bushes.

A stabilizer bar is attached to both ends of the
control arms using ball joint links. The stabilizer bar
is attached to the front underbody by brackets and
mounting rubbers.

Each front suspension unit assembly comprises a
tubular shock absorber type suspension unit, sur-
rounded at the upper end by a coil spring. On top of
the coil spring is the upper mounting which attaches
to the underside of the inner mudguard panel. The
piston rod of the suspensi on unit is attached to the
centre of the upper mounting by a rubber mounted
bearing.

When a suspension unit is found to be defective it
is recommended that both suspension units be re-
newed as a pair.

Camber is adjusted by means of a cam on the
upper steering knuckle to suspension unit mounting
bolt.

The kingpin inclination and caster are set in
production and cannot be adjusted. Any variation in
these angles will be caused by worn or damaged
components.

( 1 ) Defective suspension unit or mounting: Re-
new the faulty components.

(2) Loose or worn control arm bushes or pivot
bolts: Check and tighten or renew the worn compo-
nents. (3) Broken coil spring: Renew the coil spring,
preferably in matching pairs. (4) Worn rear hub bearing: Check and renew the
hub bearing as necessary. (5) Loose or worn stabilizer bar bushes: Check
and tighten or renew the worn components.
NOTE: As a quick guide to suspension unit
condition, bounce the vehicle up and down
(one side at a time) and observe if the vehicle
comes to rest in a single movement If the
vehicle bounces two or three times before
coming to rest the susp ension unit is suspect.
If suspect, remove the suspension unit and
check for fractures and leaks. If the
suspension unit is found to be unserviceable,
it is good practice to install two new
suspension units as a matching pair.

To check the control arm bushes or pivot
bolts, insert a lever between the suspect unit
and its mounting and lever the unit back
and forth checking for excessive movement.

Check the coil springs visually for breaks.
If the spring is found to be unserviceable, it
is good practice to install two new coil
springs as a matching pair.

Rear hub bearing noise can be diagnosed
by raising and supporting the rear of the
vehicle, spinning one wheel at a time and
listening for a rumbling noise.

2. DESCRIPTION
The independent type rear suspension consists of
a suspension unit, a knuckle assembly which incorpo-
rates the stub axle, inboard control arms and a
stabilizer bar.

The suspension unit consists of a sealed, oil filled
shock absorber, enclosed at the upper end by a coil
spring on which an upper mounting assembly is
located and attached to the body.

The shock absorber piston rod is attached to the
centre of the suspension unit upper mounting assem-
bly.

The lower end of the suspension unit is attached
to the knuckle assembly to which the brake caliper
and/or the brake backing plate is mounted.

The control arms are attached to the knuckle
assembly at the outer end, and the crossmember at the
inner end.

The stabilizer bar is attached to the knuckle
assembly and mounted to the underbody. As well as
reducing body roll when cornering it also secures the
knuckle assembly, preventing fore and aft movement.

Adjustment of the toe out is provided by a
graduated cam mounted on the rear control arm inner
pivot bolt. Each graduation on the cam is equivalent
to 2 mm adjustment.

Camber is set in production and cannot be
adjusted. If the camber is not within Specifications,
inspect the suspension components and renew the
damaged or worn components as necessary.

side and the other lead to the negative side. If there is
any indication of leakage the ohmmeter will show a
reading other than infinity. Repair or renew the brush
holder if leakage is evident.

(2) Check the brushes for adequate length.
Brushes should be renewed when their length is below
Specifications. They should be a free sliding fit in the
brush holders.

NOTE: Due to the difficulty involved in
removing and installing the brushes in the
Bosch starter motor, it is recommended that
the brush holder be renewed as an assembly.

(3) Check that the commutator is free from
pitting and burning. Clean with a petrol moistened
cloth and polish with a strip of fine glass paper.

A badly worn commutator may be repaired by
mounting in a lathe, spi nning at high speed, and
taking a light cut with a very sharp tool. After turning,
undercut the insulation between the segments.

(4) Check the armature for short circuit using an
ohmmeter.

Place one of the test lead s on the armature shaft
or core and move the other lead around the circum-
ference of the commutator. If the ohmmeter shows a
reading at any point the armature is faulty and should
be renewed.

Check the drive assembly clutch pinion teeth
for wear, scoring or chipping. A clutch in good
condition should take up the drive in one direction
only. It should rotate easily and smoothly in the
non-drive direction and the assembly should move
smoothly along the armature or drive shaft helical
splines.
Check the armature shaft bushes for wear
and renew as necessary. The old bushes must be
removed and the new ones pressed into the end
brackets using a polished mandrel of the exact diam-
eter of the armature shaft. NOTE: The new bushes must not be reamed
to size, as reaming will impair the porosity
of the bushes and cause early failure. New
bushes should be allowed to stand immersed
in clean light engine oil for one hour before
installation.

To Assemble
Assembly is a reversal of the dismantling proce-
dure with attention to the following points:

Lubricate the helix of the drive shaft lightly
with graphite grease and install the drive assembly
to
the drive shaft. Install the stop collar and snap ring, slide the
stop collar over the snap ring to lock the snap ring in
position.
Lubricate the bushes in both end brackets
sparingly with engine oil. Install the engaging lever and gear set into the
drive end bracket. Install the centre rear bracket and the engag-
ing lever seal into the drive end bracket.
Slide the brush holder assembly into position
on the commutator ensuring that the brush holders
are correctly positioned in the anchor points. Install the commutator end bracket to
the
armature, install the shims and C clip. Check that the armature end float is satisfac-
tory and adjust as necessary using shims of the correct
thickness.
Align the slot in the commutator end bracket
with the cut out on the wiring seal and install the
armature end cover to the commutator end bracket.
Install the cover retaini ng screws but do not tighten.
Ensure that the permanent magnets in the
yoke have not picked up any debris and slide the yoke
over the armature ensuring that the wiring seal locates
correctly in the slot in the yoke.

12. VEHICLE CLEANING
CLEANING THE EXTERIOR
In order to remove dirt and road grime and thus
preserve paint finish, vehicles in continuous use
should be washed at least once a week.

Before washing the paintwork, it is good policy to
first hose all dirt from the underbody and clean out
the drain holes in the doors and sill panels.

Hose the vehicle to remove as much grit as
possible and wash using a clean chamois or sponge,
ensuring that the chamois or sponge is free from dirt
or grit which could scratch the paint surface.

Avoid washing the vehicle in bright sunlight with
high temperature as this will give the paintwork a
streaky watermarked finish.

If necessary, wash the vehicle using a reputable
brand Wash and Wax liquid. The Wash and Wax
liquid will restore the paint luster and leave the
paintwork with a protective coating of wax.

After a period it may become necessary to polish
the vehicle in order to remove built up foreign matter
and give the paintwork maximum protection from
industrial fall-out and salt from sea air etc. Before
polishing the paintwork, always wash the surface to
remove as much road grime as possible. When
polishing follow the polishing instructions which come
with the polish.

NOTE: Grease, oil or tar on the paint
surface can be removed with a little kerosene
or white spirits. To prevent staining, wash
and polish the affected area as soon as the
grease, oil or tar is removed.

CLEANING VINYL TRIM
To maintain the vinyl interior trim in good
condition it should be regularly vacuumed to remove
loose dirt and then wiped with a dry or damp cloth.

If the trim is soiled or stained, the following
cleaning procedure is recommended:

Using warm water, cheese cloth and a mild
soap, thoroughly wash the affected areas.
Repeat the operation using damp cheese
cloth only.
To complete the cleaning operation wipe the
trim over with a dry piece of cheese cloth.
NOTE: If the interior trim is badly soiled or
stained, wash with a reputable brand of
upholstery cleaner care fully following the
makers instructions.

CLEANING CLOTH TRIM
Loose dirt and dust on cloth trim should be
removed with a vacuum cleaner or a very soft brush.
Do not use a whisk brush or any other type of coarse
brush or damage to the cloth could result. If the fabric
is soiled the following cl eaning procedure is recom-
mended.

Sponge the fabric ligh tly with warm water
containing a little detergen t and household ammonia.
After sponging, rub the fabric lightly. If
soiling is still apparent, re peat the sponging operation.
Use a clean dry cloth to soak up excess fluid.
