6 Steering rack-
removal and refitting

1Set the steering in the straight-ahead
mode.
2Working inside the car, disconnect thesteering shaft lower coupling by unscrewing
and removing the pinch-bolt (photo).
3Disconnect the tie-rod end balljoints from
the steering arms as described earlier in this
Chapter.
4Unscrew and remove the rack clamp
mounting bolts and withdraw the steering
gear from the car crossmember (photo).
5Refitting is a reversal of removal, but on
completion check the front wheel alignment
as described in Section 8.
7 Steering gear- overhaul
4
1A worn steering gear should not be
overhauled, but a new or factory
reconditioned unit fitted.
2After a high mileage, the following
adjustment may be needed however.
Rack damper - adjustment
3The slipper in the rack housing presses the
rack into mesh with the pinion. This cuts out
any backlash between the gears. Also, due to
its pressure, it introduces some stiffness into
the rack, which cuts out excessive reaction
from the road to the steering wheel.
4In due course, wear reduces the pressures
exerted by the slipper. The pressure is
controlled by the cover plate and a spring.
5The need for resetting of the slipper is not
easy to detect. On bumpy roads, the shockinduced through the steering will give a feeling
of play, and sometimes faint clonking can be
heard. In extreme cases, free play in the
steering may be felt, though this is rare. If the
steering is compared with that of a new rack
on another car, the lack of friction damping is
quite apparent in the ease of movement of the
steering wheel of the worn one.
6Centralise the steering rack. Do this by
counting the number of turns lock-to-lock and
then turning the steering wheel from one lock
through half the number of turns counted.
7Take the cover plate off the damping
slipper, remove the spring and shims, and refit
the cover plate.
8Screw in the cover plate bolts just enough
to hold the slipper against the rack.
9Measure the gap between the cover plate
and the rack housing using feeler blades.
10Select shims from the thicknesses
available (0.10, 0.125 and 0.30 mm) to provide
a shim pack thicker than the gap by between
0.05 and 0.13 mm.
11Remove the cover plate, fit the spring and
bolt on the cover plate with the selected shims.

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

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

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.
7 Front crossmember-
removal and refitting
3
1Raise the front of the car, support securely
with axle stands placed under the
side-members or sill jacking points.
2Remove the front roadwheels.
3Unscrew the nuts from the tie-rod end
balljoint taper pins and then using a balljoint
“splitter” tool disconnect the balljoints from
the steering arms on the hub carrier.
4Unscrew the bolts which hold the inboard
track control arms to the body members, and
also withdraw the pivot bolt from the body
bracket.
5Support the weight of the engine/
transmission using a hoist or support bar
across the top of the engine compartment as
described in Chapter 6.
6Disconnect the lower (central) engine/
transmission flexible mounting from the floor
pan.
7Unscrew the steering rack mounting boltsand remove them. Leave the steering rack
hanging loose.
8Remove the front crossmember mounting
bolts and manoeuvre it from the car.
9Refitting is a reversal of removal. Tighten all
nuts and bolts to the specified torque wrench
settings and on completion, check the front
wheel alignment as described in Chapter 10.
8 Rear shock absorber-
removal and refitting
3
1Open the tailgate and remove the cover
from the shock absorber top mounting which
is located within the luggage area (photo).
2Hold the flats on the spindle with an
open-ended spanner and then unscrew the
self-locking nut.
3Working under the car, disconnect the
shock absorber lower mounting.
4Withdraw the unit from under the wing.
5The shock absorber can be tested as
described in Section 2.
6Refitting is a reversal of removal. Tighten
mounting nuts and bolts to the specified
torque.
9 Rear coil spring-
removal and refitting
3
1Raise the rear of the car and support it
securely on axle stands placed under the
side-members or sill jacking points.
2Remove the roadwheel.
3Place a jack under the brake drum and
support the suspension trailing arm.
4Disconnect the shock absorber lower
mounting and then lower the trailing arm jack
until the coil spring can be withdrawn.
5Refitting is a reversal of removal. If the
spring is being changed, make sure that it is
of the same colour code as the original and
that its lower coil is correctly located up
against its stop in the spring pan.
6Tighten the shock absorber lower mounting
bolt to the specified torque.

1 General description
The Uno is an all steel, welded Hatchback
of unitary construction available in three- or
five-door versions.
Various levels of trim and equipment are
available depending upon model.
Factory fitted options include a sunroof,
central door locking and electrically-operated
front windows.
2 Maintenance-
bodywork and underframe
1
The general condition of a vehicle’s
bodywork is the one thing that significantly
affects its value. Maintenance is easy, but
needs to be regular. Neglect, particularly after
minor damage, can lead quickly to further
deterioration and costly repair bills. It is
important also to keep watch on those parts
of the vehicle not immediately visible, for
instance the underside, inside all the wheel
arches, and the lower part of the engine
compartment.The basic maintenance routine for the
bodywork is washing - preferably with a lot of
water, from a hose. This will remove all the
loose solids which may have stuck to the
vehicle. It is important to flush these off in
such a way as to prevent grit from scratching
the finish. The wheel arches and underframe
need washing in the same way, to remove any
accumulated mud, which will retain moisture
and tend to encourage rust. Paradoxically
enough, the best time to clean the underframe
and wheel arches is in wet weather, when the
mud is thoroughly wet and soft. In very wet
weather, the underframe is usually cleaned of
large accumulations automatically, and this is
a good time for inspection.
Periodically, except on vehicles with a wax-
based underbody protective coating, it is a
good idea to have the whole of the
underframe of the vehicle steam-cleaned,
engine compartment included, so that a
thorough inspection can be carried out to see
what minor repairs and renovations are
necessary. Steam-cleaning is available at
many garages, and is necessary for the
removal of the accumulation of oily grime,
which sometimes is allowed to become thick
in certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-applied; the dirt can then be simply hosed off.
Note that these methods should not be used
on vehicles with wax-based underbody
protective coating, or the coating will be
removed. Such vehicles should be inspected
annually, preferably just prior to Winter, when
the underbody should be washed down, and
any damage to the wax coating repaired.
Ideally, a completely fresh coat should be
applied. It would also be worth considering
the use of such wax-based protection for
injection into door panels, sills, box sections,
etc, as an additional safeguard against rust
damage, where such protection is not
provided by the vehicle manufacturer.
After washing paintwork, wipe off with a
chamois leather to give an unspotted clear
finish. A coat of clear protective wax polish
will give added protection against chemical
pollutants in the air. If the paintwork sheen
has dulled or oxidised, use a cleaner/polisher
combination to restore the brilliance of the
shine. This requires a little effort, but such
dulling is usually caused because regular
washing has been neglected. Care needs to
be taken with metallic paintwork, as special
non-abrasive cleaner/polisher is required to
avoid damage to the finish. Always check that
the door and ventilator opening drain holes
and pipes are completely clear, so that water

can be drained out (photos). Brightwork
should be treated in the same way as
paintwork. Windscreens and windows can be
kept clear of the smeary film which often
appears, by the use of proprietary glass
cleaner. Never use any form of wax or other
body or chromium polish on glass.
3 Maintenance-
upholstery and carpets
1
Mats and carpets should be brushed or
vacuum-cleaned regularly, to keep them free
of grit. If they are badly stained, remove them
from the vehicle for scrubbing or sponging,
and make quite sure they are dry before
refitting. Seats and interior trim panels can be
kept clean by wiping with a damp cloth. If they
do become stained (which can be more
apparent on light-coloured upholstery), use a
little liquid detergent and a soft nail brush to
scour the grime out of the grain of the
material. Do not forget to keep the headlining
clean in the same way as the upholstery.
When using liquid cleaners inside the vehicle,
do not over-wet the surfaces being cleaned.
Excessive damp could get into the seams and
padded interior, causing stains, offensive
odours or even rot.
4 Minor body damage-
repair
3
Note:For more detailed information about
bodywork repair, Haynes Publishing produce
a book by Lindsay Porter called “The Car
Bodywork Repair Manual”. This incorporates
information on such aspects as rust treatment,
painting and glass-fibre repairs, as well asdetails on more ambitious repairs involving
welding and panel beating.
Repairs of minor scratches in
bodywork
If the scratch is very superficial, and does
not penetrate to the metal of the bodywork,
repair is very simple. Lightly rub the area of
the scratch with a paintwork renovator, or a
very fine cutting paste, to remove loose paint
from the scratch, and to clear the surrounding
bodywork of wax polish. Rinse the area with
clean water.
Apply touch-up paint to the scratch using a
fine paint brush; continue to apply fine layers
of paint until the surface of the paint in the
scratch is level with the surrounding
paintwork. Allow the new paint at least two
weeks to harden, then blend it into the
surrounding paintwork by rubbing the scratch
area with a paintwork renovator or a very fine
cutting paste. Finally, apply wax polish.
Where the scratch has penetrated right
through to the metal of the bodywork, causing
the metal to rust, a different repair technique
is required. Remove any loose rust from the
bottom of the scratch with a penknife, then
apply rust-inhibiting paint to prevent the
formation of rust in the future. Using a rubber
or nylon applicator, fill the scratch with
bodystopper paste. If required, this paste can
be mixed with cellulose thinners to provide a
very thin paste which is ideal for filling narrow
scratches. Before the stopper-paste in the
scratch hardens, wrap a piece of smooth
cotton rag around the top of a finger. Dip the
finger in cellulose thinners, and quickly sweep
it across the surface of the stopper-paste in
the scratch; this will ensure that the surface of
the stopper-paste is slightly hollowed. The
scratch can now be painted over as described
earlier in this Section.
Repairs of dents in bodywork
When deep denting of the vehicle’s
bodywork has taken place, the first task is to
pull the dent out, until the affected bodywork
almost attains its original shape. There is little
point in trying to restore the original shape
completely, as the metal in the damaged area
will have stretched on impact, and cannot be
reshaped fully to its original contour. It isbetter to bring the level of the dent up to a
point which is about 3 mm below the level of
the surrounding bodywork. In cases where the
dent is very shallow anyway, it is not worth
trying to pull it out at all. If the underside of the
dent is accessible, it can be hammered out
gently from behind, using a mallet with a
wooden or plastic head. Whilst doing this,
hold a suitable block of wood firmly against
the outside of the panel, to absorb the impact
from the hammer blows and thus prevent a
large area of the bodywork from being
“belled-out”.
Should the dent be in a section of the
bodywork which has a double skin, or some
other factor making it inaccessible from
behind, a different technique is called for. Drill
several small holes through the metal inside
the area - particularly in the deeper section.
Then screw long self-tapping screws into the
holes, just sufficiently for them to gain a good
purchase in the metal. Now the dent can be
pulled out by pulling on the protruding heads
of the screws with a pair of pliers.
The next stage of the repair is the removal
of the paint from the damaged area, and from
an inch or so of the surrounding “sound”
bodywork. This is accomplished most easily
by using a wire brush or abrasive pad on a
power drill, although it can be done just as
effectively by hand, using sheets of abrasive
paper. To complete the preparation for filling,
score the surface of the bare metal with a
screwdriver or the tang of a file, or
alternatively, drill small holes in the affected
area. This will provide a really good “key” for
the filler paste.
To complete the repair, see the Section on
filling and respraying.
Repairs of rust holes or gashes
in bodywork
Remove all paint from the affected area,
and from an inch or so of the surrounding
“sound” bodywork, using an abrasive pad or a
wire brush on a power drill. If these are not
available, a few sheets of abrasive paper will
do the job most effectively. With the paint
removed, you will be able to judge the severity
of the corrosion, and therefore decide
whether to renew the whole panel (if this is
possible) or to repair the affected area. New
body panels are not as expensive as most
people think, and it is often quicker and more
satisfactory to fit a new panel than to attempt
to repair large areas of corrosion.
Remove all fittings from the affected area,
except those which will act as a guide to the
original shape of the damaged bodywork (eg
headlight shells etc). Then, using tin snips or a
hacksaw blade, remove all loose metal and
any other metal badly affected by corrosion.
Hammer the edges of the hole inwards, in
order to create a slight depression for the filler
paste.
Wire-brush the affected area to remove the
powdery rust from the
surface of the remaining metal. Paint the

affected area with rust-inhibiting paint, if the
back of the rusted area is accessible, treat
this also.
Before filling can take place, it will be
necessary to block the hole in some way. This
can be achieved by the use of aluminium or
plastic mesh, or aluminium tape.
Aluminium or plastic mesh, or glass-fibre
matting, is probably the best material to use
for a large hole. Cut a piece to the
approximate size and shape of the hole to be
filled, then position it in the hole so that its
edges are below the level of the surrounding
bodywork. It can be retained in position by
several blobs of filler paste around its
periphery.
Aluminium tape should be used for small or
very narrow holes. Pull a piece off the roll, trim
it to the approximate size and shape required,
then pull off the backing paper (if used) and
stick the tape over the hole; it can be
overlapped if the thickness of one piece is
insufficient. Burnish down the edges of the
tape with the handle of a screwdriver or
similar, to ensure that the tape is securely
attached to the metal underneath.
Bodywork repairs - filling and
respraying
Before using this Section, see the Sections
on dent, deep scratch, rust holes and gash
repairs.
Many types of bodyfiller are available, but
generally speaking, those proprietary kits
which contain a tin of filler paste and a tube of
resin hardener are best for this type of repair. A
wide, flexible plastic or nylon applicator will be
found invaluable for imparting a smooth and
well-contoured finish to the surface of the filler.
Mix up a little filler on a clean piece of card
or board - measure the hardener carefully
(follow the maker’s instructions on the pack),
otherwise the filler will set too rapidly or too
slowly. Using the applicator, apply the filler
paste to the prepared area; draw the
applicator across the surface of the filler to
achieve the correct contour and to level the
surface. As soon as a contour that
approximates to the correct one is achieved,
stop working the paste - if you carry on too
long, the paste will become sticky and begin
to “pick-up” on the applicator. Continue to
add thin layers of filler paste at 20-minute
intervals, until the level of the filler is just
proud of the surrounding bodywork.
Once the filler has hardened, the excess
can be removed using a metal plane or file.
From then on, progressively-finer grades of
abrasive paper should be used, starting with a
40-grade production paper, and finishing with
a 400-grade wet-and-dry paper. Always wrap
the abrasive paper around a flat rubber, cork,
or wooden block - otherwise the surface of
the filler will not be completely flat. During the
smoothing of the filler surface, the wet-and-
dry paper should be periodically rinsed in
water. This will ensure that a very smooth
finish is imparted to the filler at the final stage.At this stage, the “dent” should be
surrounded by a ring of bare metal, which in
turn should be encircled by the finely
“feathered” edge of the good paintwork.
Rinse the repair area with clean water, until all
of the dust produced by the rubbing-down
operation has gone.
Spray the whole area with a light coat of
primer - this will show up any imperfections in
the surface of the filler. Repair these
imperfections with fresh filler paste or
bodystopper, and once more smooth the
surface with abrasive paper. Repeat this
spray-and-repair procedure until you are
satisfied that the surface of the filler, and the
feathered edge of the paintwork, are perfect.
Clean the repair area with clean water, and
allow to dry fully.
The repair area is now ready for final
spraying. Paint spraying must be carried out
in a warm, dry, windless and dust-free
atmosphere. This condition can be created
artificially if you have access to a large indoor
working area, but if you are forced to work in
the open, you will have to pick your day very
carefully. If you are working indoors, dousing
the floor in the work area with water will help
to settle the dust which would otherwise be in
the atmosphere. If the repair area is confined
to one body panel, mask off the surrounding
panels; this will help to minimise the effects of
a slight mis-match in paint colours. Bodywork
fittings (eg chrome strips, door handles etc)
will also need to be masked off. Use genuine
masking tape, and several thicknesses of
newspaper, for the masking operations.
Before commencing to spray, agitate the
aerosol can thoroughly, then spray a test area
(an old tin, or similar) until the technique is
mastered. Cover the repair area with a thick
coat of primer; the thickness should be built
up using several thin layers of paint, rather
than one thick one. Using 400-grade wet-and-
dry paper, rub down the surface of the primer
until it is really smooth. While doing this, the
work area should be thoroughly doused withwater, and the wet-and-dry paper periodically
rinsed in water. Allow to dry before spraying
on more paint.
Spray on the top coat, again building up the
thickness by using several thin layers of paint.
Start spraying at one edge of the repair area,
and then, using a side-to-side motion, work
until the whole repair area and about 2 inches
of the surrounding original paintwork is
covered. Remove all masking material 10 to 15
minutes after spraying on the final coat of
paint.
Allow the new paint at least two weeks to
harden, then, using a paintwork renovator, or
a very fine cutting paste, blend the edges of
the paint into the existing paintwork. Finally,
apply wax polish.
5 Major body damage-
repair

1Major repair to the body should be left to
your Fiat dealer or specialist body repairer.
2Special jigs and alignment gauges are
required without which steering and
suspension characteristics may be incorrect
after the repairs are completed.

3With the help of an assistant, support the
weight of the bonnet, unbolt the hinges and
lift the bonnet from the car.
4Refitting is a reversal of removal, but do not
fully tighten the hinge bolts until the bonnet
has been gently closed and its alignment
checked. If the gap between the bonnet and
the front wings is not equal on both sides,
release the hinge bolts and move the bonnet
within the elongation provided at the bolt
holes.8 Bonnet lock and release
1
1The bonnet lock is operated by a remote
control lever inside the car through a cable
(photo).
2When closing the bonnet, the spring-loaded
striker should enter the lock centrally. If it
does not, release the lock bolts and slide the
lock as necessary (photo).3Engagement of the striker in the lock should
be adjusted for depth in order that the surface
of the bonnet is level with the front wings. To
do this, release the striker locknut and turn the
striker in or out by inserting a screwdriver in
its slot.
4In conjunction with the striker adjustment,
screw the bonnet rubber buffers in or out as
necessary to provide secure rattle-free
closure of the bonnet (photo).
5If the lock must be removed, first withdraw
the radiator grille as described in Section 6.
6To renew the release cable, unclip and
lower the release lever under the facia panel.
7Disconnect the cable from the lever and
then slip it from the lock operating arm.
Withdraw the cable.
8Refit the new cable by reversing the
removal operations.
9 Front bumpers-
removal and refitting

1Remove the radiator grille as described in
Section 6 to expose the two upper bumper
fixing screws. Remove them (photos).
2Working inside at the lower edge of the
bumper remove the three fixing bolts.
3Finally, unscrew the side bracket fixing
bolts and lift the bumper away.
4Refitting is a reversal of removal.

front and rear ends.
6Open the bonnet and support it. Then
unscrew and remove the row of fixing screws
from the inner top edge of the wing.
7The wing joints will have to be cut round
with a sharp knife to release the mastic seal
before the wing can be lifted away.
8Clean the body mating flanges in readiness
for fitting the new wing.
9Apply a bead of mastic to the body flanges
and offer the new wing into position.
10Refit the fixing screws.
11Apply protective coating to the underside
of the wing and refinish the outer surface to
match the bodywork. 12Refit the headlamp, parking lamp and
