1983 FIAT UNO steering wheel

Note: Before diagnosing steering faults, be
sure that trouble is not due to incorrect or
uneven tyre pressures, inappropriate tyre
combinations, or braking system or
suspension defects.

check that the tyres are correctly inflated, that
the front wheels are not buckled, the hub
bearings are not worn or incorrectly adjusted
and that the steering linkage is in good order,
without slackness or wear at the joints.
2Wheel alignment consists of four factors:
Camber, is the angle at which the road
wheels are set from the vertical when viewed
from the front or rear of the vehicle. Positive
camber is the angle (in degrees) that the wheels
are tilted outwards at the top from the vertical.
Castor, is the angle between the steering
axis and a vertical line when viewed from each
side of the vehicle. Positive castor is indicated
when the steering axis is inclined towards the
rear of the vehicle at its upper end.
Steering axis inclination, is the angle when
viewed from the front or rear of the vehicle
between vertical and an imaginary line drawn
between the upper and lower suspension
strut mountings.
Toe,is the amount by which the distance
between the front inside edges of the
roadwheel rims differs from that between the
rear inside edges.
3If the distance between the front edges is
less than that at the rear, the wheels are said
to toe-in. If the distance between the front
inside edges is greater than that at the rear,
the wheels toe-out.
4Camber and castor are set during
production of the car and are not adjustable.
Any deviation from specification will be due tocollision damage or to gross wear in the
components concerned.
5To check the front wheel alignment, first
make sure that the lengths of both tie-rods are
equal when the steering is in the straight-ahead
position. Measure between the locknut at the
balljoint and the ball cup at the end of the rack
housing by passing a thin rod under the rack of
the gaiter. If adjustment is required, release the
locknut and turn the tie-rod.
6Obtain a tracking gauge. These are
available in various forms from accessory
stores or one can be fabricated from a length
of steel tubing suitably cranked to clear the
sump and bellhousing and having a setscrew
and locknut at one end.
7With the gauge, measure the distance
between the two wheel inner rims (at hub
height) at the rear of the wheel. Push the
vehicle forward to rotate the wheel through
180º (half a turn) and measure the distance
between the wheel inner rims, again at hub
height, at the front of the wheel. This last
measurement should differ from (be less than)
the first by the appropriate toe-in according to
the Specification (see Specifications Section).
8Where the toe-in is found to be incorrect,
release the tie-rod balljoint locknuts and turn
the tie-rods equally. Only turn them a quarter
of a turn at a time before re-checking the
alignment. Viewed from the centre line of the
car, turning the tie-rod clockwise will
decrease the toe-in.
9Make sure that the gaiter outboard clip isreleased otherwise the gaiter will twist as the
tie-rod is rotated.
10Always turn both rods in the same
direction when viewed from the centre line of
the vehicle otherwise the rods will become
unequal in length. This would cause the
steering wheel spoke position to alter and
cause problems on turns with tyre scrubbing.
11On completion, tighten the tie-rod balljoint
locknuts without altering their setting. Check
that the balljoint is at the centre of its arc of
travel and then retighten the gaiter clip.
9 Steering column lock-
removal and refitting
1
1Remove the steering wheel and column
shrouds as described in Section 5, also the
steering column combination switch.
2Unscrew and remove the steering column
mounting bolts and lower the column to
expose the lock shear bolts.
3Drill out the bolts or extract them using an
extractor.
4Refer to Chapter 4 for details of separation
of the ignition switch from the lock section.
5When fitting the new lock, tighten the shear
bolts until their heads break off.
6Bolt up the column, fit the combination
switch, shrouds and steering wheel and
tighten all nuts and bolts to the specified
torque.

“splitter” tool. If such a tool is not available,
support the base of the brake disc and drive
the balljoint taper pin downwards, but screw
on the nut to protect the threads.
4Remove the hub carrier.
5Refitting is a reversal of removal, use a new
driveshaft nut and tighten all nuts and bolts to
the specified torque. Stake the driveshaft nut
after tightening.
6 Track control arm-
removal and refitting
3
1Raise the front of the car and support it
securely.
2Unless a special tool is available to press
the track control arm balljoint from the hub
carrier, the driveshaft will have to be
disconnected as described in Chapter 7,
Section 2, paragraphs 1 to 8 to provide more
space to enable the balljoint taper pin to be
driven from the hub carrier. This should now
be done as described in the preceding
Section (photo).
3Unbolt the inboard end of the track control
arm. This is retained by a pivot bolt and a
clamp (photo).
4As previously explained, a worn balljoint or
flexible pivot bushes will necessitate renewal
of the track control arm complete. Note that itmay, however, be possible to obtain a
replacement balljoint through a motor factor.
5Refitting is a reversal of removal. Tighten all
nuts and bolts to the specified torque. Use a
new driveshaft nut and stake it into the
driveshaft groove after tightening.

Vacuum servo unit and master
cylinder - general
54Access to the vacuum servo unit and the
master cylinder can only be obtained after the
cooling system expansion tank has been
released and moved aside (photo).
Antiskid system - description
55This system is available as an option on
the Turbo ie models only.
56The purpose of the system is to prevent
the wheel(s) locking during heavy brake
applications. This is achieved by automatic
release of the brake on a roadwheel which is
about to lock up, after which the brake is
re-applied. This cycle is carried out many
times per second under heavy braking,
retaining full steering control to avoid any
hazards.
57The main components of the system are
shown in Fig. 13.102. The control module
processes the signals received from the
sensors, and compares them with
deceleration values of the roadwheel and the
slip values of the tyre, which are stored in the
module memory.
58When reference values are exceeded and
wheel lock is imminent, the control module
signals the pressure modulators, which in turn
decrease the brake hydraulic pressure.
59Vehicle road speeds are also taken into
account by the module’s electronic circuits.
60In order to retain optimum system
performance, the tyres and wheels shouldalways be of the type originally fitted by the
vehicle manufacturer.
61Maintenance of the system should be
limited to checking the security of all electrical
and hydraulic connections. Individual compo-
nents are not repairable, and must be
renewed complete if faulty.15 Electrical system

adjustment procedures are the same as those
outlined for the previous model units in
Chapter 9, but ensure that the load
compensation lever is turned to the “O”
(normal load setting) position before making
any adjustments.
Headlamp unit removal - later
models
32The removal and refitting procedures
described in Chapter 9 also apply to the later
headlamp type, but note that later units are
secured in position by three retaining screws.
Headlamp dim-dip system -
description
33On later models, the wiring circuit has
been modified to prevent the car being drivenon parking lamps only in built-up areas.
34Headlamp intensity is reduced by the
transformer located at the front of the engine
compartment (photo).
35Any attempt to start the car with parking
lamps only on will automatically cause the
headlamps to switch on with a low-intensity
