Models before August 1989
1Remove the stub axle carrier as described
in the previous Section.
2Screw the wheel nuts onto the studs to
protect the threads. Clamp the stub axle
carrier in a vice by means of the studs and
nuts; do not overtighten.
3Remove the dust cap from the hub nut,
carefully levering it free (see illustration). A
new cap and a new hub nut will be required for
reassembly.
4Undo the hub nut. This nut is very tight. The
right-hand hub nut has a left-handthread,
therefore it is undone in a clockwisedirection.
5Remove the ABS rotor from below the hub
nut.
6Lift the carrier off the stub axle, tapping it
with a mallet if necessary to free it. Remove
the bearing inner race from the carrier.
7Prise the oil seal out of the carrier and
recover the bearing outer race.8Drive the bearing tracks out of the stub axle
carrier using a blunt drift and a hammer. Be
careful not to mark the bearing seats.
9Clean all old grease and debris from the
stub axle carrier.
10New bearing components are matched in
production and must only be fitted as a set.
Only the manufacturer’s approved
components should be used in order to obtain
the required long service life and freedom from
adjustment.
11Drive the new bearing tracks into the
carrier, preferably using a suitable diameter
tube to seat them. Make sure the tracks are
fully seated.
12Work some clean grease into the bearing
races. Use high melting-point lithium-based
grease (to Ford spec. SAMIC-9111A or
equivalent). Make sure all the spaces between
the rollers are filled; do not pack grease into
the space between the inner and outer
bearings however.
13Fit the bearing outer race. Grease the lips
of a new oil seal and fit it to the stub axle
carrier, lips facing inwards. Seat the seal with
a pipe or large socket and a mallet.
14Offer the carrier to the stub axle, tapping it
home if necessary. Fit the bearing inner race
over the stub axle.
15Refit the ABS rotor, dished face
uppermost.
16Fit a new hub nut (left-hand thread on the
right-hand hub) and tighten it to the specified
torque.17Fit a new dust cap and seat it by tapping
round the rim (see illustration).
18Refit the stub axle carrier.
Models from August 1989
19Modified front wheel bearing assemblies
were fitted to all models after 1989. The
modified bearings are of similar design, but
are interference fit type bearings. This was to
reduce the amount of endfloat present at the
wheel hub and to improve bearing preload
tolerances. This was achieved by increasing
the diameter of the stub axle, thus causing the
axle to be an interference fit in the bearing.
Note that the modified bearings can be fitted
to earlier models which were originally
equipped with non-interference fit front wheel
bearings. Note: Due to the design of the
interference fit bearings, a suitable heavy duty
bearing puller and a hydraulic press and
several suitable mandrels will be required to
remove the originalbearing and install the new
one.
20Interference fit front wheel bearings can be
removed and refitted as described above,
noting the following points.
a)It will be necessary to press or draw the
stub axle out of the carrier using a
hydraulic press or a suitable bearing
puller.
b)Draw the outer bearing off the stub axle
using a suitable bearing puller.
c)Press new bearing tracks into the hub
carrier using a suitable tubular spacer
which bears only on the tracks outer edge.
d)Pack the new outer bearing with Ford
grease (SAM-1C9111-A) and press the
bearing into the carrier.
e)Press a new seal into position in the
carrier and pack all cavities with the
specified grease.
f)Position the hub carrier over the stub axle
and press the carrier onto the axle using a
suitable tubular spacer which bears only
on the bearing track outer edge.
g)Pack the new inner bearing with the
specified grease then press the bearing
onto the stub axle, using a suitable tubular
spacer, whilst rotating the hub carrier to
ensure that the bearing is correctly seated.
h)Whilst tightening the hub nut to the
specified torque, rotate the hub carrier to
ensure that the bearing preload is correct
and bearings are correctly seated. Once
the nut is tightened to the specified
torque, rotate the hub carrier 20 times to
settle the bearings in position then
recheck that the hub nut is tightened to
the specified torque. Pack the inner
bearing with the specified grease and fit a
new dust cap.

1Raise the vehicle on ramps or on a hoist, so
that the weight is still on the wheels.
2Remove the lower arm pivot nut and bolt
(see illustration).
3Remove the anti-roll bar end nut, dished
washer and plastic cover. Note which way
round these components are fitted.
4Now raise and support the vehicle so that
the front wheels are off the ground.
5Remove the split pin from the lower arm
balljoint nut. Back off the nut a few turns,
break the taper with a balljoint separator, then
remove the nut and free the balljoint from the
stub axle carrier.
6Pull the lower arm off the anti-roll bar and
remove it.
7If the balljoint is defective, the whole arm
must be renewed. The dust boot can be
renewed separately if required.
8The anti-roll bar bushes (compliance
bushes) can be removed by cutting off their
flanges with a chisel, then pressing or tapping
out the remains. Fit new bushes by tapping
them home with a tube or socket.
9The pivot bush can be pressed out using a
bench vice and a couple of large sockets or
suitable pieces of tube. The new pivot bush
should be lubricated with soap or glycerine
(notoil or grease) before being fitted in a
similar fashion. Do not keep the new bush
compressed in the tube for longer than
necessary, in case it becomes permanently
distorted.
10Commence refitting by offering the arm to
the anti-roll bar. Make sure that the shallow
dished washer and the plastic cover are fitted
on the inboard side of the bar (furthest from
the nut).
11Refit the balljoint to the stub axle carrier.
Tighten the castellated nut to the specified
torque and secure it with a new split pin.
12Fit the pivot end of the arm into the
crossmember and secure it with the pivot nut
and bolt. Jacking the vehicle up or down to
vary the loading on the wheels may help to get
the holes lined up. Do not tighten the pivot nut
and bolt yet.
13Lower the vehicle back onto its wheels.14Fit the deep dished washer and the plastic
cover over the end of the anti-roll bar. Fit the
nut and tighten it to the specified torque.

of the anti-roll bar to the lower arms. Recover
the plastic covers and deep dished washers.
5Remove one lower arm pivot nut and bolt.
Prise the lower arm out of the crossmember
and work the anti-roll bar free from it.
6Pull the anti-roll bar out of the other lower
arm and remove it. Recover the other
compliance bush covers and washers.
7Refit by reversing the removal operations,
but do not finally tighten any fastenings until
the weight of the vehicle is back on the
wheels. Tighten in the following order:
a)Anti-roll bar clamps
b)Anti-roll bar-to lower arm nuts
c)Lower arm pivot nut and bolt
8Make sure that the anti-roll bar clamp
bushes are not twisted on completion.
Compliance bushes
1These are described in Section 18. It is not
strictly necessary to remove the lower arms to
renew these bushes, though obviously access
is not good with the arms installed.
Clamp bushes
2Although it is possible to remove and refit
the clamp bushes without removing the anti-
roll bar, since the bushes are split, this is not
recommended by the makers.
3Remove the anti-roll bar as described in the
previous Section.4Slide the clamp bushes off the anti-roll bar,
if necessary prising them open a little first.
5Lubricate the new bushes with glycerine or
soap and slide them into position with the split
facing forwards.
6Refit the anti-roll bar.
1Slacken the front wheel nuts, raise and
support the vehicle and remove the front
wheel.

3Fit spring compressors to the strut.
Compress the spring until it is no longer
tensioning the strut. Make sure that the
compressors are secure (see illustration).
4Hold the piston rod with a hexagon key and
remove the piston rod nut. Also remove the
dished retainer.
5Remove the top mount, the bearing and the
spring upper seat(see illustration).
6Carefully lift off the compressed spring.
Place it where it will not be knocked or jarred.
7Remove the shock absorber gaiter and
bump stop.
8Examine all components for wear and
damage and renew as necessary. The shock
absorber must be renewed if it is leaking, or if
it shows uneven resistance when “worked”
with its lower end clamped in a vice. In theory
springs and shock absorbers should be
renewed in pairs in order to maintain balanced
handling characteristics.
9Commence reassembly by sliding the bump
stop onto the shock absorber piston rod. Refit
the gaiter.
10Make sure that the spring seats are clean,
then fit the compressed spring to the lower
seat.
11Refit the spring upper seat, the bearing
(small hole upwards) and the top mount.
12Refit the dished retainer and the piston rod
nut. Hold the piston rod and tighten the nut.13Carefully release the spring compressors.
Make sure that the ends of the spring are
correctly located in the spring seats.
14Spread the stub axle carrier again. Slide it
onto the strut, remove the spreader and refit
the pinch-bolt. Tighten the pinch-bolt to the
specified torque.
15Refit the strut to the vehicle.

Models from 1987
16From 1987, the tab washer which secures
the guide plate centre bolt on each side has
been deleted. A self-locking bolt and plain
washer are used instead.
17The new bolt and washer should be fitted
to earlier models if the old bolt has been
removed for any reason. The tab washer
should be discarded.
18The tightening torque for the new bolt
remains the same as that given for the original.
1Remove the wheel trim. Apply the
handbrake and chock the front wheels.

disconnect the air line from the shock
absorber.
4Unbolt the shock absorber top mounting
(see illustration).
5Unbolt the shock absorber lower mounting
(see illustration). Pull the shock absorber out
of the lower mounting bracket and remove it.
6Refit by reversing the removal operations.
Tighten the shock absorber mountings to the
specified torque. On models with ride height
control, use new O-rings on the air line union.
The ride height control system is an optional
extra, designed to keep the rear suspension
height constant regardless of vehicle load.
This is obviously useful if heavy loads are often
carried, or if the vehicle is used for towing.
The main components of the system are a
height sensor, a compressor and two special
rear shock absorbers. The compressor
supplies air to the shock absorbers, so
“pumping up” the rear suspension, when so
commanded by the height sensor. Other
components include the connecting pipes,
electrical wiring and a compressor relay. The
relay is mounted behind the glovebox.
Variations in vehicle height are not
recognised by the system for approximately
20 seconds, in order to prevent responses to
temporary changes such as those induced by

REF•14Glossary of Technical Terms
GGapThe distance the spark must travel in
jumping from the centre electrode to the side
electrode in a spark plug. Also refers to the
spacing between the points in a contact
breaker assembly in a conventional points-
type ignition, or to the distance between the
reluctor or rotor and the pickup coil in an
electronic ignition.
GasketAny thin, soft material - usually cork,
cardboard, asbestos or soft metal - installed
between two metal surfaces to ensure a good
seal. For instance, the cylinder head gasket
seals the joint between the block and the
cylinder head.
GaugeAn instrument panel display used to
monitor engine conditions. A gauge with a
movable pointer on a dial or a fixed scale is an
analogue gauge. A gauge with a numerical
readout is called a digital gauge.
HHalfshaftA rotating shaft that transmits
power from the final drive unit to a drive
wheel, usually when referring to a live rear
axle.
Harmonic balancerA device designed to
reduce torsion or twisting vibration in the
crankshaft. May be incorporated in the
crankshaft pulley. Also known as a vibration
damper.
HoneAn abrasive tool for correcting small
irregularities or differences in diameter in an
engine cylinder, brake cylinder, etc.
Hydraulic tappetA tappet that utilises
hydraulic pressure from the engine’s
lubrication system to maintain zero clearance
(constant contact with both camshaft and
valve stem). Automatically adjusts to variation
in valve stem length. Hydraulic tappets also
reduce valve noise.
IIgnition timingThe moment at which the
spark plug fires, usually expressed in the
number of crankshaft degrees before the
piston reaches the top of its stroke.
Inlet manifoldA tube or housing with
passages through which flows the air-fuel
mixture (carburettor vehicles and vehicles with
throttle body injection) or air only (port fuel-
injected vehicles) to the port openings in the
cylinder head.
JJump startStarting the engine of a vehicle
with a discharged or weak battery by
attaching jump leads from the weak battery to
a charged or helper battery.
LLoad Sensing Proportioning Valve (LSPV)A
brake hydraulic system control valve that
works like a proportioning valve, but also
takes into consideration the amount of weight
carried by the rear axle.
LocknutA nut used to lock an adjustment
nut, or other threaded component, in place.
For example, a locknut is employed to keep
the adjusting nut on the rocker arm in
position.
LockwasherA form of washer designed to
prevent an attaching nut from working loose.
MMacPherson strutA type of front
suspension system devised by Earle
MacPherson at Ford of England. In its original
form, a simple lateral link with the anti-roll bar
creates the lower control arm. A long strut - an
integral coil spring and shock absorber - is
mounted between the body and the steering
knuckle. Many modern so-called MacPherson
strut systems use a conventional lower A-arm
and don’t rely on the anti-roll bar for location.
MultimeterAn electrical test instrument with
the capability to measure voltage, current and
resistance.
NNOxOxides of Nitrogen. A common toxic
pollutant emitted by petrol and diesel engines
at higher temperatures.
OOhmThe unit of electrical resistance. One
volt applied to a resistance of one ohm will
produce a current of one amp.
OhmmeterAn instrument for measuring
electrical resistance.
O-ringA type of sealing ring made of a
special rubber-like material; in use, the O-ring
is compressed into a groove to provide the
sealing action.
Overhead cam (ohc) engineAn engine with
the camshaft(s) located on top of the cylinder
head(s).Overhead valve (ohv) engineAn engine with
the valves located in the cylinder head, but
with the camshaft located in the engine block.
Oxygen sensorA device installed in the
engine exhaust manifold, which senses the
oxygen content in the exhaust and converts
this information into an electric current. Also
called a Lambda sensor.
PPhillips screwA type of screw head having a
cross instead of a slot for a corresponding
type of screwdriver.
PlastigageA thin strip of plastic thread,
available in different sizes, used for measuring
clearances. For example, a strip of Plastigage
is laid across a bearing journal. The parts are
assembled and dismantled; the width of the
crushed strip indicates the clearance between
journal and bearing.
Propeller shaftThe long hollow tube with
universal joints at both ends that carries
power from the transmission to the differential
on front-engined rear wheel drive vehicles.
Proportioning valveA hydraulic control
valve which limits the amount of pressure to
the rear brakes during panic stops to prevent
wheel lock-up.
RRack-and-pinion steeringA steering system
with a pinion gear on the end of the steering
shaft that mates with a rack (think of a geared
wheel opened up and laid flat). When the
steering wheel is turned, the pinion turns,
moving the rack to the left or right. This
movement is transmitted through the track
rods to the steering arms at the wheels.
RadiatorA liquid-to-air heat transfer device
designed to reduce the temperature of the
coolant in an internal combustion engine
cooling system.
RefrigerantAny substance used as a heat
transfer agent in an air-conditioning system.
R-12 has been the principle refrigerant for
many years; recently, however, manufacturers
have begun using R-134a, a non-CFC
substance that is considered less harmful to
the ozone in the upper atmosphere.
Rocker armA lever arm that rocks on a shaft
or pivots on a stud. In an overhead valve
engine, the rocker arm converts the upward
movement of the pushrod into a downward
movement to open a valve.
